CraftOil hydraulic equipment · Stock and service in Ukraine · Technical assistance with equipment selection

The CraftOil 3 kW dual-flow hydraulic power unit with foot-pedal control is designed for industrial workstations that require reliable hydraulic operation throughout a production shift. It combines a three-phase 380 V electric motor, a two-line hydraulic circuit for compatible double-acting cylinders, electromagnetic directional control and a 30-litre oil reservoir.

With a specified maximum pressure of 70 MPa (700 bar), a first-stage flow rate of 14 L/min and a second-stage flow rate of 2.8 L/min, this hydraulic power pack is intended for demanding applications such as cable lug crimping, hydraulic pressing, cable cutting and other compatible industrial hydraulic operations.

The foot pedal controls the hydraulic flow through an electromagnetic valve, allowing operators to keep their hands available for positioning and securing the workpiece. The three-phase motor is suitable for facilities with an appropriate 380 V electrical supply.

This configuration is particularly worth considering for cable-processing plants, electrical installation companies, production workshops and service departments where hydraulic tools are used repeatedly throughout the working day.

Why choose a 3 kW, 380 V hydraulic power unit with a foot pedal?

For repetitive industrial work, the motor power, electrical supply and control method all matter. This configuration combines a three-phase motor with foot-pedal operation to support an organised production workflow.

1. Three-phase power for industrial applications

A 380 V three-phase motor is designed for facilities with a suitable three-phase electrical supply. Compared with a single-phase configuration of similar rated power, it generally offers balanced operation across the phases and does not require the same single-phase starting-capacitor arrangement.

The supplied reference current for this configuration is approximately 6–7 A per phase. Actual current depends on the motor, load, supply conditions and starting characteristics; the electrical installation must be selected and checked by a qualified electrician.

Important: A three-phase supply is required for this version. If your facility only has a 220 V single-phase supply, ask CraftOil about the corresponding single-phase model.

2. Foot-pedal control for repetitive work

When positioning a cable lug under a crimping tool, an operator may need both hands to keep the cable and die aligned. Foot-pedal control allows the hydraulic function to be operated without reaching for a manual lever.

Potential benefits include:

• Easier workpiece positioning during repeated operations

• Less movement between the work area and the hydraulic control

• A more convenient workflow at high-volume workstations

• Consistent operation when used with the correct tooling and procedure

The actual cycle time depends on the connected cylinder, its displacement, the operating pressure and the task.

3. Electromagnetic flow control

The foot pedal operates the electromagnetic directional valve, which controls hydraulic flow. In this configuration, the motor can run while the operator uses the pedal to control the hydraulic function, subject to the unit’s operating instructions and thermal limits.

This can reduce the need to start and stop the motor for every individual operation. However, continuous operation should not be assumed to be appropriate under all conditions. At high idle-flow rates, hydraulic oil can heat up, so the operating cycle and oil temperature must be monitored.

4. Dual-flow operation for compatible double-acting cylinders

The dual-flow circuit supplies the cylinder’s two working chambers in the required sequence, allowing powered extension and powered retraction when used with a compatible double-acting cylinder and the correct valve arrangement.

This is useful when:

• The cylinder has two hydraulic ports

• The piston must retract under hydraulic pressure

• The application requires a controlled return stroke

• A spring-return mechanism is unsuitable for the task

The correct hose arrangement and directional-valve configuration must be confirmed before connection. The term “dual-flow” alone does not establish compatibility with every hydraulic cylinder.

Hydraulic flow rate and estimated cycle time

The pump has two specified flow stages:

• First stage: 14 L/min at 2 MPa (20 bar)

• Second stage: 2.8 L/min at 70 MPa (700 bar)

The higher first-stage flow supports faster movement under low-pressure conditions, while the lower second-stage flow corresponds to the high-pressure stage.

The following table shows idealised filling-time estimates based on the supplied second-stage flow rates for different power-unit configurations. These figures are mathematical estimates, not guaranteed real-world cycle times.

Actual extension and retraction times depend on the effective cylinder area, stroke, working pressure, hydraulic circuit, oil viscosity and system losses. For a double-acting cylinder, both chamber volumes and the flow required for the return stroke must be considered.

The foot pedal can also reduce unnecessary operator movement. Any productivity improvement depends on the existing workstation and production process.

Technical specifications

Electrical protection, conductor cross-section and connection requirements must be confirmed by a qualified electrician in accordance with the motor nameplate, manufacturer’s documentation and local electrical regulations.

Is the 30-litre oil tank sufficient?

Reservoir capacity is an important factor when selecting a hydraulic power unit. The tank must accommodate the oil required by the connected equipment while maintaining a suitable reserve and providing sufficient thermal capacity for the operating cycle.

As a preliminary sizing guideline, reserving approximately 20–30% of the nominal tank capacity leaves around 21–24 L for planning purposes in a 30 L reservoir. This is an estimate, not a guaranteed maximum cylinder displacement. The usable oil volume and the actual requirement depend on the cylinder, hose volume, circuit design and the manufacturer’s instructions.

There is also a thermal consideration. A traditional preliminary rule of thumb for reservoir sizing is approximately three to five times the pump’s high-flow rating. If the relevant flow is 14 L/min, this gives a reference range of approximately 42–70 L. This is not a universal design requirement, but it indicates why oil temperature deserves attention when using a 30 L tank under intensive operating conditions.

For demanding production cycles:

• Monitor the hydraulic oil temperature.

• Avoid leaving the unit running unnecessarily when no work is being performed.

• Check the reservoir level before operation.

• Follow the specified duty cycle and maintenance instructions.

• Ask CraftOil to review the operating cycle if the station will run for long periods or under heavy load.

The three-phase motor does not eliminate hydraulic heat generation. Thermal performance depends on the complete hydraulic system, not only on the motor type.

Pressure gauge: 1,000 bar scale, 700 bar operating limit

The supplied glycerine-filled pressure gauge has a scale up to 1,000 bar, while the hydraulic power unit’s specified maximum pressure is 700 bar.

Glycerine helps damp needle vibration and can make pressure readings easier to observe in vibrating environments. The gauge scale provides a measurement range beyond the unit’s specified operating pressure.

A 1,000 bar gauge does not increase the permitted working pressure to 1,000 bar. The power unit, cylinders, hoses, couplings, adapters and connected tools must all be rated for the intended operating pressure. Never exceed the lowest applicable pressure rating in the system.

Standard package contents

The standard package includes:

• Dual-flow hydraulic power unit, 3 kW, 380 V

• Foot-pedal control

• Electric motor control unit

• 2 m high-pressure hydraulic hose

• Quick-release coupling

• Glycerine-filled pressure gauge, scale up to 1,000 bar

• Pressure gauge adapter

• Operating instructions

Hydraulic oil is not included. The reservoir capacity is 30 L, but the actual filling quantity depends on the system and the specified oil level. Contact CraftOil for help selecting an appropriate hydraulic oil.

Applications: what can this hydraulic power pack operate?

Subject to pressure, flow, cylinder displacement and circuit compatibility, the unit may be suitable for:

• Cable lug crimping presses

• Hydraulic cable cutters

• Busbar bending machines

• Hydraulic presses, including cable-processing presses

• Double-acting hydraulic cylinders

• Hydraulic jacks designed for the appropriate circuit

• Pipe-bending equipment

• Bearing and pulley pullers

• Other compatible hydraulic tools rated for the required pressure and flow

The maximum pressure rating alone is not enough to establish compatibility. Before connecting equipment, verify the cylinder type, number of hydraulic ports, required oil volume, return method, operating pressure and connection specifications.

Who should consider this model?

The 3 kW, 380 V dual-flow power unit with foot-pedal control is especially relevant to:

• Cable manufacturing plants

• Electrical installation companies with production-scale workloads

• Industrial workshops with a three-phase power supply

• Cable assembly and crimping stations

• Service and repair departments with repeated hydraulic operations

• Production facilities where the operator benefits from keeping both hands on the workpiece

For occasional use or equipment with modest hydraulic requirements, a lower-power configuration may be sufficient. CraftOil can help you compare the available options.

Compare CraftOil hydraulic power-unit configurations

CraftOil offers different combinations of motor supply and operator control. The following comparison uses the supplied specifications.

How to select the right version

Do you have a three-phase supply? If yes, the 380 V version may be suitable. If your facility has only a single-phase 220 V supply, consider the corresponding 220 V model.

Does your cylinder have two hydraulic ports? A compatible dual-flow circuit may be required for powered extension and retraction. Confirm the circuit and valve arrangement before ordering.

Are both hands occupied during production? Foot-pedal control can improve workstation ergonomics when the workpiece needs manual positioning.

What is the required oil volume? Compare the actual cylinder displacement and circuit volume with the usable reservoir capacity. A nominal 30 L tank does not automatically guarantee compatibility with every cylinder up to a particular volume.

Compatibility with CraftOil hydraulic presses

CraftOil manufactures hydraulic presses rated at 50 and 70 tonnes and works with hydraulic equipment in its own workshop. This practical experience helps us discuss the requirements of a press installation, rather than relying on catalogue descriptions alone.

When enquiring about a power unit, provide the following information:

• The hydraulic press or tool model

• The cylinder’s number of ports and whether it is single- or double-acting

• Cylinder displacement or relevant cylinder dimensions

• Required working pressure

• Number of operations per shift

• Whether a three-phase electrical supply is available

• Expected operating cycle and workload

Based on these details, CraftOil can help assess the required configuration and identify whether a 3 kW, 380 V unit is appropriate or whether a simpler option may be sufficient.

Which hydraulic oil should you use?

The exact oil specification must be checked in the equipment manual. The supplied product information lists the following oil types for consideration:

• Industrial hydraulic oil with ISO VG 32 or ISO VG 46 viscosity

• HLP 32 or HLP 46 hydraulic oil

• I-20A or MGE-46V equivalents, where approved for the specific unit and operating conditions

These products should not be treated as automatically interchangeable. Select oil according to the manufacturer’s instructions, ambient temperature, operating temperature and hydraulic-system requirements.

Oil filling and maintenance

• Fill the reservoir to the level specified by the manufacturer.

• Use clean hydraulic oil and suitable filtration when filling.

• Check the oil level before the first start.

• Keep the oil clean to reduce the risk of valve malfunction.

• Monitor oil temperature during intensive operation.

• Inspect for leaks and deterioration.

• Follow the manufacturer’s oil-change interval and maintenance schedule.

The supplied source information gives approximately one year as a preliminary oil-change interval, or earlier if the oil becomes dark or develops a burnt smell. Actual service intervals should follow the manufacturer’s manual and operating conditions.

First start-up: checking three-phase motor rotation

With a three-phase motor, the direction of rotation depends on the phase sequence. Incorrect rotation can prevent the pump from developing pressure and may cause inadequate lubrication or damage.

For this reason, the first connection must be performed by a qualified electrician in accordance with the motor and power-unit documentation.

Before commissioning:

1. Verify the oil level and confirm that the unit is correctly filled.

2. Check the electrical connections, protective earth and required protective devices.

3. Perform the initial rotation check strictly according to the manufacturer’s procedure.

4. If the unit does not develop pressure, stop operation immediately and have the phase sequence checked.

5. Do not continue running the pump if rotation is incorrect or the pump is not properly supplied with oil.

Do not change electrical phase connections while the equipment is energised. Any correction must be carried out by a qualified electrician with the power isolated and secured.

Safety and operating recommendations

High-pressure hydraulic equipment requires careful installation and operation.

• Have the three-phase electrical connection completed by a qualified electrician.

• Use protective earthing and electrical protection appropriate to the installation.

• Verify the motor’s rotation direction during commissioning.

• Position the foot pedal to prevent accidental activation and keep its cable away from walkways.

• Inspect hydraulic hoses, fittings and couplings before operation.

• Confirm the A and B line connections before pressurising a double-acting cylinder.

• Never disconnect a quick coupling while the hydraulic circuit is pressurised.

• Wear appropriate eye protection and follow the instructions for the connected tool.

• Never exceed the specified pressure rating of the cylinder, hoses, couplings or accessories.

• The unit weighs approximately 52 kg; use suitable lifting equipment or a two-person handling procedure as appropriate.

Follow the operating manual and all applicable workplace and electrical safety requirements.

Frequently asked questions

What is the advantage of the foot-pedal version over the lever-operated version?

The foot pedal allows the operator to control the hydraulic function while keeping both hands available for workpiece positioning. The motor and valve operate according to the unit’s control arrangement and operating instructions. This can be useful in repetitive production, but the appropriate operating cycle must be followed to avoid unnecessary oil heating.

Why choose 380 V instead of 220 V?

The 380 V version uses a three-phase motor. For a similar rated power, three-phase motors generally distribute the electrical load across three phases and do not use the same single-phase starting-capacitor arrangement. The correct choice depends on the electrical supply available at the facility.

Can this model be connected to a single-phase 220 V supply?

No. This version is specified for 380 V three-phase power. If you only have a single-phase supply, ask CraftOil about the corresponding 220 V configuration.

What should I do if the pump does not develop pressure after connection?

Stop the unit and have the electrical connection and motor rotation checked by a qualified electrician in accordance with the manufacturer’s commissioning procedure. Incorrect phase sequence is one possible cause, but other hydraulic or electrical issues may also prevent pressure from developing.

Can the motor run all day?

The appropriate duty cycle depends on the unit’s design, operating conditions and oil temperature. Although the motor may be able to run for extended periods, unnecessary idle operation can heat the oil. Use the manufacturer’s operating instructions and monitor the hydraulic system during intensive production.

What is the maximum connected cylinder volume?

There is no universal maximum cylinder volume that can be established from the 30 L reservoir capacity alone. The usable oil volume, cylinder displacement, hose volume, return-side requirements and thermal operating conditions must all be considered. CraftOil can help review the application if you provide the cylinder specifications.

What hydraulic oil is required?

Use the oil grade specified in the equipment manual. ISO VG 32 or VG 46 hydraulic oils are listed as possible options in the supplied product information, but the final choice must be confirmed for the specific unit and operating conditions.

What is the warranty period?

The specified warranty period is three months. Contact CraftOil for the applicable warranty conditions and service support.

· Available from stock in Kharkiv, Ukraine · Warranty and service in Ukraine · Same-day dispatch when in stock

The CraftOil HHB-700D3 three-outlet hydraulic power unit is designed for industrial workstations where several hydraulic tools need to remain connected and be selected as required. Its three hydraulic outlets allow operators to switch between connected tools using the directional valve instead of repeatedly disconnecting and reconnecting hydraulic hoses.

The unit features electromagnetic flow control operated by a foot pedal, allowing the operator to keep both hands available for positioning and securing the workpiece.

With a maximum operating pressure of 70 MPa (700 bar), a 0.75 kW electric motor, a 7-litre oil reservoir and 220 V single-phase power supply, the HHB-700D3 is a practical solution for cable-processing stations, hydraulic assembly workstations, service centres and industrial applications that use multiple high-pressure hydraulic tools.

Key specifications

• Maximum pressure: 700 bar (70 MPa)

• Hydraulic outlets: 3

• Flow control: electromagnetic directional valve with foot pedal

• Motor power: 0.75 kW

• Power supply: 220 V, single-phase

• Oil reservoir capacity: 7 L

• Weight: 30 kg

• Pump type: two-stage hydraulic pump

Why choose a three-outlet hydraulic power unit?

At a cable-processing workstation, operators may use a cable crimping press, a hydraulic cable cutter and a punching tool during the same shift. With a single-outlet hydraulic power unit, changing tools may require releasing pressure, disconnecting a quick coupling, connecting another tool and restoring the operating setup.

The HHB-700D3 allows up to three hydraulic lines to remain connected. The operator selects the required line using the directional valve, reducing the need for repeated hose changes.

Practical advantages

1. Less downtime when changing tools

Keeping several tools connected reduces the time spent disconnecting and reconnecting hoses. The actual time saved depends on the tools, workstation layout and number of changes per shift. At a workstation with ten changes per shift, avoiding several minutes per change can add up to approximately half an hour of saved time.

2. Fewer repeated coupling operations

Quick couplings are subject to mechanical wear every time they are connected and disconnected. Reducing unnecessary coupling cycles can help extend their service life.

3. Reduced exposure to dirt

Disconnecting hydraulic couplings can expose connection surfaces to dust and other contaminants. Keeping connections protected and unused outlets capped helps maintain hydraulic oil cleanliness.

4. Less oil leakage during tool changes

Repeated disconnection can result in small oil spills. Keeping tools connected can reduce this source of leakage and help maintain a cleaner workstation.

5. A more organised workstation

Three permanently connected hydraulic lines can make a multi-tool workstation easier to organise, provided that each line is clearly labelled and the hoses are routed safely.

Important operating limitation: The HHB-700D3 has one hydraulic pump. Its three outlets provide three connected hydraulic lines, not three independent pumps. The hydraulic supply is switched between the lines; the unit is not designed to power three tools simultaneously. Confirm the required circuit and valve configuration before ordering.

Foot-pedal control: keep your hands on the workpiece

When crimping a cable lug or positioning a component under a hydraulic press, the operator often needs both hands to hold and align the workpiece. Foot-pedal control lets the operator activate the hydraulic function without reaching for a manual lever.

Benefits include:

• Improved positioning: the operator can keep the workpiece aligned as the hydraulic tool begins its stroke.

• Convenient operation: foot control can be useful in repetitive work where both hands are occupied.

• A more practical workstation layout: the control pedal can be positioned near the operator while the hydraulic unit remains in a suitable location.

Actual cycle time depends on the connected tool, workpiece, required pressure and operating procedure. The foot pedal and electromagnetic valve are additional electrical components and require inspection and maintenance. CraftOil can advise on replacement parts available in Ukraine, including pedals and valve coils.

Typical connection configurations

The three-outlet design can be useful in several types of workstation:

• Three cable crimping tools for different cable lug sizes or conductor cross-sections, selected one at a time.

• A hydraulic press, cable cutter and hydraulic punching tool at the same workstation.

• A configuration with a double-acting cylinder on an appropriate hydraulic circuit and a single-acting tool on another line, subject to valve and circuit compatibility.

• A primary tool and a pre-connected standby tool, allowing a quicker changeover if the primary tool needs servicing.

The correct configuration depends on the connected equipment, cylinder type, number of ports, return mechanism, hose connections and required hydraulic circuit. Confirm compatibility with CraftOil before purchase.

Technical specifications

The gauge scale extends to 1,000 bar, while the power unit’s specified maximum pressure is 700 bar. The higher gauge scale does not increase the unit’s operating pressure rating.

Oil reservoir capacity and hydraulic tool compatibility

The HHB-700D3 has a 7-litre oil reservoir. Reservoir capacity alone does not establish compatibility with every cylinder or hydraulic tool.

As a preliminary sizing guideline, allowing a 20–30% oil reserve suggests considering connected equipment with a working oil requirement of approximately 5.5 litres or less. This is an estimate, not a universal compatibility limit. The actual requirement depends on usable reservoir volume, cylinder displacement, hose volume, the hydraulic circuit and the manufacturer’s operating instructions.

When several tools are connected, check the oil requirement of the largest cylinder and verify the complete hydraulic system before use. Contact CraftOil if you need help checking the configuration.

220 V power supply and generator operation

The HHB-700D3 uses a 0.75 kW motor and a 220 V single-phase power supply. It is intended for use with a suitable, properly installed electrical supply.

For generator operation, a generator in the 1.5–2 kW range may be a preliminary starting point for consideration, but suitability must be confirmed against the motor’s starting current, generator continuous and surge ratings, voltage stability and any other connected loads. Do not select a generator based on motor rated power alone.

Use a properly grounded supply and follow the operating manual and local electrical safety requirements.

Why is the pressure gauge rated up to 1,000 bar?

The HHB-700D3 is specified for a maximum pressure of 700 bar, while the supplied glycerine-filled pressure gauge has a scale up to 1,000 bar.

The wider scale provides additional range on the gauge. Glycerine helps damp needle vibration and makes the pressure reading easier to observe in conditions where vibration is present.

Important: The gauge does not increase the permitted pressure of the power unit or connected tools. All hydraulic components—including cylinders, hoses, couplings, adapters and tools—must be rated for the pressure and operating conditions of the system.

Package contents

The standard package includes:

• HHB-700D3 hydraulic power unit

• Foot-pedal control

• Electric motor control unit

• 2 m high-pressure hydraulic hose

• Quick-release coupling

• Glycerine-filled pressure gauge, scale up to 1,000 bar

• Pressure gauge adapter

• Operating instructions

• Factory packaging

Please note: The standard package includes one hydraulic hose. To keep three tools connected, additional compatible hoses and quick couplings may be required. Tell us which tools you plan to use when ordering, and CraftOil can help configure the required accessories.

Hydraulic oil is not included and must be selected according to the equipment manual and operating conditions.

Compatible hydraulic equipment and applications

The HHB-700D3 may be suitable for compatible hydraulic equipment designed for the unit’s operating specifications, including:

• Cable lug crimping presses

• Hydraulic cable cutters

• Hydraulic punching tools

• Hydraulic presses

• Hydraulic power cylinders

• Hydraulic jacks

• Busbar bending machines

• Pipe benders

• Bearing and pulley pullers

• Other compatible hydraulic tools rated for the required pressure and circuit configuration

The maximum pressure rating alone does not guarantee compatibility. Check the tool’s required flow, oil displacement, cylinder action, return mechanism, connection type and pressure rating before connecting it.

Who is the HHB-700D3 best suited for?

This model is particularly worth considering for:

• Industrial production workstations using several hydraulic tools

• Cable-processing and electrical installation workshops

• Service and repair centres

• Assembly and maintenance teams

• Workshops that frequently change between different hydraulic tools during a shift

If you use only one hydraulic tool and rarely change equipment, a simpler single-outlet model may be more economical. Ask CraftOil to compare the available options before ordering.

Choosing the right CraftOil hydraulic power unit

The following comparison is based on the supplied model specifications.

How to choose

One tool at the workstation: Consider the HHB-700A, a single-outlet model with foot-pedal control.

Two tools: Compare the dual-outlet models and choose according to the required control method and hydraulic circuit.

Three tools connected with changeover between lines: Consider the HHB-700D3, provided that its outlet arrangement and valve configuration match your equipment.

Hands occupied during operation: A foot-pedal model may be more convenient, depending on the workstation and operating procedure.

Double-acting cylinders: Confirm the number of cylinder ports and the required directional-valve and return configuration before ordering. The number of outlets alone does not establish compatibility with a double-acting cylinder.

Compatibility with CraftOil hydraulic presses

CraftOil manufactures hydraulic presses rated at 30 and 50 tonnes. Our experience working with hydraulic equipment in our own workshop helps us understand the practical requirements of press operation and equipment selection.

Before recommending a power unit, we can help you review:

• Which hydraulic tools will be connected

• How many hydraulic ports each cylinder has

• Whether the tools use single-acting or double-acting cylinders

• The oil displacement required by the largest cylinder

• The number of tool changes per shift

• Whether additional hoses, couplings or adapters are needed

This helps ensure that the selected power unit and connection arrangement are suitable for your actual workstation.

Which hydraulic oil should you use?

The exact hydraulic oil specification must be confirmed in the equipment manual. The supplied product information lists the following options for consideration:

• Industrial hydraulic oil with ISO VG 32 or ISO VG 46 viscosity

• HLP 32 or HLP 46 hydraulic oils

• I-20A or MGE-46V equivalents, where approved for the unit and operating conditions

Do not assume that all oils listed above are interchangeable in every application. Select the oil according to the manufacturer’s instructions, operating temperature and system requirements.

Oil capacity and cleanliness

• Check the usable oil volume against the displacement of the connected cylinder and the complete hydraulic circuit.

• Fill the system using clean oil and appropriate filtration.

• Keep unused quick couplings protected with suitable caps.

• Inspect the oil condition and follow the service intervals specified in the manual.

• Do not mix different hydraulic oils unless the manufacturers confirm compatibility.

Contamination can cause hydraulic valve components to stick or operate incorrectly. Keeping the oil clean is especially important for a system with an electromagnetic directional valve.

The oil change interval should follow the manufacturer’s maintenance instructions and the actual operating conditions. Discoloured oil, a burnt smell or other signs of deterioration warrant inspection.

Safety and operating recommendations

High-pressure hydraulic systems require careful handling. Before operating the HHB-700D3:

1. Label all three hydraulic lines. Use matching labels on the power unit outlets and corresponding hoses to reduce the risk of selecting the wrong line.

2. Check the active line before each operation. Make sure the connected tool is correctly installed and ready for use.

3. Protect unused outlets. Fit suitable caps to prevent dust and debris entering the hydraulic connections.

4. Route hoses safely. Keep hoses away from walkways, sharp edges, moving parts and areas where they could be crushed.

5. Position the foot pedal carefully. Prevent accidental activation and keep its cable out of walkways.

6. Inspect hoses and couplings. Cracks, bulges, leaks or damaged fittings require attention before operation.

7. Never disconnect a quick coupling under pressure. Depressurise the system according to the manufacturer’s procedure first.

8. Wear suitable eye protection and follow the safety instructions for the connected hydraulic tool.

9. Use a properly grounded electrical supply and inspect electrical cables and controls.

10. Respect the pressure rating of every component. The 700 bar maximum applies to the power unit; it does not mean that every connected tool can safely operate at 700 bar.

Always follow the operating manual and the safety requirements applicable to your equipment and workplace.

Frequently asked questions

Can the HHB-700D3 operate three hydraulic tools at the same time?

No. The unit has one pump, and its hydraulic supply is switched between the three connected lines. The advantage is that tools can remain connected without repeatedly changing hoses. The unit does not provide three independent hydraulic supplies for simultaneous operation.

Why use three outlets instead of reconnecting a quick coupling?

Keeping tools connected reduces repeated coupling operations, helps limit contamination at connection points and can reduce the time spent changing tools. It also helps reduce small oil spills and wear caused by frequent connection and disconnection.

How many hydraulic hoses are included?

One 2 m high-pressure hose is included in the standard package. Additional compatible hoses and quick couplings may be required to keep three tools connected.

What is the maximum connected cylinder volume?

The 7 L reservoir suggests a preliminary planning estimate of approximately 5.5 L of working oil volume when allowing a 20–30% reserve. This is not a guaranteed compatibility limit. Check cylinder displacement, usable oil volume, hoses and the hydraulic circuit before use.

Can it run from a standard 220 V outlet?

The unit is designed for a 220 V single-phase supply. The electrical installation must be suitable for the motor and comply with the operating manual and local electrical safety requirements.

Can it run from a generator?

Potentially, subject to generator suitability. A 1.5–2 kW generator is only a preliminary estimate; starting current, surge capacity, voltage stability and other loads must be checked.

What should I do with unused hydraulic outlets?

Protect unused outlets with suitable caps to help prevent dust and debris from entering the hydraulic system.

What if the foot pedal does not operate the valve?

Stop operation and inspect the system according to the manufacturer’s troubleshooting procedure. Possible causes include a cable, electrical connection or solenoid-coil issue. Do not work on electrical components while the unit is energised. Contact CraftOil for service guidance and spare-part availability.

What is the warranty period?

The specified warranty period is three months. Contact CraftOil for warranty conditions and current service arrangements.

• 1.7 L/min high-pressure flow: helps reduce cylinder filling time compared with the specified 0.75 kW models.

• 7.9 L/min first-stage flow: supports faster initial movement when operating conditions allow.

• 10-litre oil reservoir: suitable for a range of compatible hydraulic tools, subject to their oil-volume requirements.

• Single-flow design: a straightforward solution when powered cylinder retraction is not required.

• 220V single-phase supply: suitable for compatible electrical installations.

• Service support in Ukraine: technical consultations and spare parts available through CraftOil, subject to stock availability.

Who Should Choose the DB150-D1?

The DB150-D1 is intended for applications where the hydraulic cylinder operates in one direction under pump pressure and returns through its designed mechanical mechanism or the weight of the load.

Typical users include:

• Electrical installation teams with regular cable crimping operations.

• Manufacturing workshops and assembly facilities.

• Hydraulic service centres.

• Repair and maintenance workshops.

• Industrial contractors performing repeated hydraulic operations.

• Production teams that need to reduce waiting time between working cycles.

If your tool requires hydraulic pressure in both directions, choose a compatible dual-flow power unit instead.

Single-Flow or Dual-Flow: Which Hydraulic Power Unit Do You Need?

Before choosing a hydraulic power pack, check the cylinder’s hydraulic circuit and the tool manufacturer’s specifications.

Single-acting cylinder: hydraulic pressure drives the working stroke. The cylinder returns by a spring, gravity or another designed return mechanism. A compatible single-flow unit such as the DB150-D1 may be suitable.

Double-acting cylinder: hydraulic pressure is required to drive the cylinder in both directions. This requires a compatible dual-flow power unit, such as the DB150-S2 or DB150-D2, subject to the tool’s specifications.

A cylinder with one hydraulic port is commonly single-acting, while one with two ports is commonly double-acting. However, port count alone should not replace checking the manufacturer’s documentation.

The DB150-D1 is a practical choice when your equipment does not need a powered return stroke. You get the higher specified flow rate of the 1.5 kW model without paying for a dual-flow circuit that your application does not use.

What Does the 1.5 kW Motor Mean for Working Speed?

For hydraulic equipment, the time required to extend a cylinder depends on the oil volume needed for the stroke and the actual flow delivered by the pump at the operating pressure.

The supplied specifications list a high-pressure flow rate of 1.7 L/min for the DB150-D1, compared with 0.9 L/min for the specified 0.75 kW models.

Using those nominal flow rates, the approximate filling times for different cylinder oil volumes are:

These are theoretical estimates based on the stated flow rates. Actual cycle time depends on operating pressure, cylinder characteristics, hydraulic losses, valve configuration and the return stroke.

For a team performing dozens of similar operations per shift, a shorter working stroke can improve overall productivity. The actual time saved depends on the equipment and work process.

Why Choose a Single-Flow Hydraulic Circuit?

The DB150-D1 uses a single-flow hydraulic configuration for applications that do not require powered cylinder retraction.

Potential advantages include:

• Straightforward hydraulic layout: no dual-flow circuit is needed when the connected cylinder is single-acting.

• A configuration matched to the application: avoid paying for a hydraulic function your tool does not require.

• Simplified troubleshooting: fewer circuit functions can make fault diagnosis more straightforward.

• Practical maintenance: routine service focuses on the components actually used by the system.

The best configuration is the one that matches your tool. If powered retraction is required, a dual-flow model is necessary regardless of the motor power or reservoir size.

Technical Specifications — CraftOil DB150-D1

Specifications are based on the supplied product information. Confirm the exact control configuration and operating requirements against the documentation for the specific unit before purchase.

Is the 10-Litre Reservoir Suitable for Your Hydraulic Tool?

Reservoir capacity is an important part of selecting a hydraulic power unit. The pump needs enough usable oil to complete the required cylinder stroke while maintaining a suitable oil level in the tank.

As a preliminary selection guideline, the DB150-D1’s 10-litre reservoir may suit equipment with an approximate working oil displacement of up to 8 litres. This is not a universal hydraulic design limit. The actual requirement depends on the cylinder displacement, hose volume, hydraulic circuit and usable reservoir capacity.

For equipment requiring more oil, consider a power unit with a larger reservoir, such as a 30-litre model.

Before connecting the DB150-D1 to a press or other hydraulic system, confirm:

• Whether the cylinder is single-acting.

• The oil volume required for the complete working stroke.

• The hydraulic pressure and flow requirements.

• The usable oil capacity needed for safe operation.

A reservoir that is too small for the system can lead to air entering the hydraulic circuit, unstable operation and potential equipment damage.

Electrical Supply: 220V Operation

The DB150-D1 is specified for a 220V single-phase electrical supply. The stated approximate current draw is 7 A.

Before operation, make sure the electrical circuit, socket, protective devices and grounding are suitable for the equipment.

For safe and reliable operation:

• Use a suitable power cable with an appropriate conductor cross-section.

• Avoid thin or excessively long extension leads that may cause voltage drop.

• Do not operate the unit with an extension cable tightly coiled, as this can increase heat build-up.

• Ensure proper grounding and electrical protection.

• Follow the manufacturer’s electrical installation instructions.

A generator may be suitable if its continuous output, starting capacity and voltage stability meet the motor’s requirements. Confirm generator compatibility before use rather than relying on nominal wattage alone.

Why Does the Pressure Gauge Read up to 1,000 Bar?

The DB150-D1 is specified for a maximum operating pressure of 700 bar, while the supplied glycerine-filled pressure gauge has a scale extending to 1,000 bar.

The higher gauge scale does not increase the power unit’s maximum working pressure. The 700 bar limit remains applicable, and all connected cylinders, hoses, fittings, couplings and tools must be rated for the intended operating pressure.

Glycerine helps dampen needle vibration, making pressure readings easier to observe during operation.

Package Contents

The CraftOil DB150-D1 package includes:

The CraftOil HHB-700A single-flow hydraulic power unit is designed for professionals who need convenient foot-pedal control without paying for a dual-flow hydraulic system they do not require.

With a maximum working pressure of 70 MPa (700 bar), a 0.75 kW electric motor and a 7-litre oil reservoir, this electro-hydraulic power pack is suitable for compatible single-acting hydraulic tools used in cable installation, electrical assembly, workshop operations and equipment maintenance.

The electromagnetic directional valve is controlled by a foot pedal, allowing the operator to keep both hands available for positioning the workpiece and hydraulic tool. The power unit operates from a standard 220V single-phase electrical supply and weighs approximately 25 kg.

The HHB-700A is a practical choice for repetitive hydraulic operations where hands-free control improves convenience, positioning and workflow.

Key Benefits of the HHB-700A Hydraulic Power Pack

• 700 bar maximum pressure: for hydraulic tools rated for the required working pressure.

• Foot-pedal control: activate the hydraulic function without reaching for a manual control lever.

• Single-flow hydraulic circuit: a straightforward solution for compatible single-acting cylinders.

• 7-litre oil reservoir: suitable for a wider range of compact and medium-volume hydraulic tools than many smaller portable units, subject to oil-volume requirements.

• 0.75 kW electric motor: designed for operation from a compatible 220V single-phase supply.

• Two-stage hydraulic pump: high flow at the first stage and lower flow at high pressure.

• Service support in Ukraine: technical consultations and spare parts available through CraftOil, subject to stock availability.

How Does the HHB-700A Work?

The HHB-700A uses a single-flow hydraulic circuit with electromagnetic valve control operated by a foot pedal.

When the pedal activates the hydraulic function, the pump supplies oil to the connected single-acting cylinder. When the hydraulic pressure is released, the cylinder returns through its designed return mechanism, typically a spring or the weight of the load, depending on the tool.

This configuration is commonly used with hydraulic equipment that requires pressure in one direction and does not need a powered return stroke.

Typical examples include compatible cable crimping tools, hydraulic punching tools and single-acting presses.

Important: The HHB-700A does not provide a powered return stroke for a double-acting cylinder. If your tool requires hydraulic pressure to extend and retract the cylinder, choose a compatible dual-flow power unit instead.

How to Check Whether You Need a Single-Flow or Dual-Flow Unit

Look at the hydraulic cylinder and check the tool manufacturer’s specifications.

• One hydraulic port: the tool may be designed for single-acting operation, making the HHB-700A a possible match.

• Two hydraulic ports: the tool may require a dual-flow power unit, such as the HHB-700AB or DB075-D2, depending on its control and performance requirements.

The number of ports is a useful preliminary check, but it is not a substitute for confirming the cylinder’s hydraulic circuit and operating instructions.

Why Choose Foot-Pedal Control?

In repetitive work, both hands are often needed to position the tool and workpiece. A manual lever may require the operator to release the component, reach for the control and then reposition everything for the next cycle.

The HHB-700A’s foot pedal is designed to make this workflow more convenient.

Practical Advantages

1. More consistent positioning

The operator can keep their hands on the cable, connector or workpiece while activating the hydraulic function. This can help reduce unwanted movement during repetitive operations.

2. Convenient repetitive operation

Foot-pedal control is useful when performing the same hydraulic operation many times throughout the day. Actual cycle time depends on the connected tool, working pressure, stroke and operator workflow.

3. Better attention to the workpiece

The operator can concentrate on alignment and positioning instead of repeatedly reaching for a control mounted on the power unit.

4. Flexible teamwork

Where two-person operation is appropriate, one person can position the tool while the other operates the foot pedal.

An Honest Note About Electromagnetic Controls

The foot pedal and electromagnetic valve add electrical components that can require maintenance or replacement. A manual directional lever has fewer electrical control components.

In return, the pedal offers convenient hands-free activation. CraftOil can provide technical guidance, and commonly needed parts such as pedals and electromagnetic valve coils are available in Ukraine, subject to stock availability.

HHB-700A Compared with Other CraftOil Hydraulic Power Units

The HHB-700A is positioned for users who need foot-pedal control but do not require dual-flow operation.

Specifications are based on the supplied product information. Confirm the exact configuration for the model and production batch before ordering.

Why Does the HHB-700A Weigh Less Than the DB075-D2?

The HHB-700A weighs approximately 25 kg, while the dual-flow DB075-D2 weighs approximately 32 kg. The difference reflects their different configurations.

If your tool only requires single-flow operation, the HHB-700A provides foot-pedal control without the need for a dual-flow hydraulic circuit.

If your cylinder requires powered movement in both directions, choose a compatible dual-flow model instead.

Which Model Should You Choose?

Choose the HHB-700A if:

• Your tool uses a compatible single-acting cylinder.

• You want foot-pedal control.

• Repetitive operations make hands-free activation useful.

• The 7-litre reservoir meets your system’s oil-volume requirements.

Choose the HHB-700AB if:

• Your tool requires dual-flow operation.

• You prefer the specified manual-valve and remote-control configuration.

Choose the DB075-D2 if:

• You need dual-flow operation with foot-pedal control.

• Your tool’s hydraulic and electrical requirements match this model.

Choose the DYB-63A if:

• Your tool uses a compatible single-acting cylinder.

• You prefer manual-lever control over a foot pedal.

The right choice depends on the cylinder’s hydraulic circuit, oil displacement, pressure and flow requirements, as well as how frequently the tool will be used.

Technical Specifications — CraftOil HHB-700A

Confirm the exact motor-control configuration, oil specification and operating requirements against the documentation supplied with the unit.

What Can the 7-Litre Oil Reservoir Operate?

Reservoir capacity is an important factor when selecting a hydraulic power unit. The pump needs enough usable oil to complete the required cylinder stroke while maintaining a safe oil level in the tank.

As a preliminary selection guideline, a 7-litre reservoir may suit equipment with an approximate working oil displacement of up to 5.5 litres. This is not a universal limit: the actual requirement depends on the cylinder displacement, hose volume, hydraulic circuit and usable reservoir capacity.

For larger cylinders, a power unit with a 10-litre or 30-litre reservoir may be more appropriate.

Before connecting the HHB-700A to a press or another hydraulic system, confirm that the cylinder is single-acting and calculate the required oil volume.

Electrical Supply and Generator Operation

The HHB-700A uses a 0.75 kW electric motor and a 220V single-phase power supply.

The supplied product information gives an approximate current draw of 4 A. A suitable household electrical outlet may be sufficient, provided the supply, protective devices, grounding and wiring are in good condition.

The unit may also be suitable for generator operation. A generator in the 1.5–2 kW range is a preliminary option to consider, but compatibility depends on the generator’s continuous output, motor starting current, voltage stability and any other connected loads.

For safe operation:

• Check the generator’s continuous and starting power ratings.

• Allow the generator to stabilise before starting the power unit.

• Avoid overloading the generator with other equipment.

• Ensure proper electrical grounding and follow the relevant electrical safety instructions.

Why Is the Pressure Gauge Rated up to 1,000 Bar?

The HHB-700A is specified for a maximum operating pressure of 700 bar, while its glycerine-filled pressure gauge has a scale extending to 1,000 bar.

The higher gauge scale does not increase the power unit’s maximum working pressure. The 700 bar limit remains applicable, and every connected component must be rated for the intended pressure.

Glycerine helps dampen needle vibration, which can make the pressure reading easier to observe during operation.

The CraftOil QQ-700-2 dual-flow hydraulic power unit is designed for professionals who need high hydraulic pressure, controlled cylinder movement and portability at the job site. Weighing approximately 15 kg, this compact electro-hydraulic power pack combines a two-stage pump, a 2-litre oil reservoir, electromagnetic directional control and a foot pedal.

With a maximum working pressure of 70 MPa (700 bar) and a 1.2 kW electric motor, the QQ-700-2 is intended for compatible double-acting hydraulic tools used in electrical installation, cable maintenance, equipment servicing and industrial field work.

Unlike a single-flow hydraulic pump, the QQ-700-2 can supply hydraulic oil to both sides of a compatible double-acting cylinder. This allows the operator to control both the working stroke and the return stroke under hydraulic pressure, rather than relying solely on a return spring.

The foot pedal helps keep the operator’s hands available for positioning the workpiece, cable or tool. Combined with its compact design and standard 220V single-phase power supply, the QQ-700-2 is a practical option for mobile service teams and installation crews.

Key Benefits of the QQ-700-2 Hydraulic Power Pack

• Dual-flow hydraulic operation: designed for compatible double-acting cylinders with two hydraulic ports.

• Foot-pedal control: allows hands-free activation of the hydraulic control system.

• 700 bar maximum pressure: suitable for hydraulic tools rated for the required pressure.

• Portable design: approximately 15 kg for easier transportation between job sites.

• Two-stage pump: provides a high-flow first stage and a lower-flow high-pressure stage.

• 220V single-phase power: operates from a compatible electrical supply.

• Compact 2 L oil reservoir: reduces overall size and weight for mobile applications.

• Service support in Ukraine: spare parts and technical consultations available through CraftOil.

Why Choose a Dual-Flow Hydraulic Pump for Field Work?

At a workshop, an operator may have room to reposition equipment or disassemble a tool. At a remote installation site, a stuck hydraulic tool can quickly interrupt the entire job.

A dual-flow hydraulic power unit is designed to address applications where the cylinder needs hydraulic pressure in both directions.

Example: A Cable Cutter with a Jammed Blade

If a cable cutter blade becomes stuck while cutting a particularly difficult cable, a single-flow system with spring return may not be able to retract the blade under the existing load.

A compatible dual-acting hydraulic system can apply pressure to the return side of the cylinder, helping retract the blade without relying solely on a spring.

The same principle can be useful with compatible hydraulic pullers, clamping equipment and other tools that require powered cylinder retraction.

How to check your tool: look at the hydraulic cylinder. A cylinder with one hydraulic port is generally configured for single-acting operation; a cylinder with two ports is generally configured for double-acting operation. Always confirm the tool manufacturer’s specifications and hydraulic circuit before selecting a power unit.

Why Use a Foot Pedal?

The QQ-700-2 features foot-pedal control for situations where the operator needs both hands to position and support the work.

Practical advantages include:

• Hands available for positioning: hold the cable, align a crimping die or position the workpiece while activating the hydraulic system.

• More convenient operation: the operator does not need to reach for a control lever on the power unit for every operation.

• Useful in restricted work areas: a foot pedal may be easier to operate than a control mounted on the pump, depending on the installation layout.

• Efficient teamwork: one person can position the tool while another operates the pedal, where the job requires two operators.

Foot-pedal operation does not replace safe work procedures. Position the pedal where it cannot be activated accidentally, keep the cable away from walkways and moving equipment, and ensure the operator can stop the process safely.

Important: Check the Foot Pedal’s Environmental Protection Rating

On construction sites, in cable pits and outdoors, the foot pedal may be exposed to dust, moisture and rain. Before ordering, ask CraftOil to confirm the pedal’s IP protection rating and cable length for the specific production batch.

If your application requires continuous operation in wet conditions, confirm that the equipment is suitable for that environment before purchase. A hydraulic power unit with a manual directional valve may be a more appropriate option for some applications.

Compact Design: What You Should Know About the 2-Litre Oil Tank

The 2-litre reservoir is one of the main design trade-offs of a lightweight portable hydraulic power unit. It helps reduce the size and weight of the equipment, but it also limits the volume of oil available to operate a hydraulic cylinder.

As a preliminary selection guideline, the QQ-700-2 is intended for compatible tools with an approximate working oil displacement of up to 1.5 litres. The actual suitability must be checked against the usable reservoir capacity, cylinder displacement, hose volume, operating stroke and hydraulic circuit.

These figures are guidelines, not universal hydraulic design limits. The required oil volume must be calculated for the actual cylinder and system. Allowance is needed for the oil remaining in the reservoir, hoses and other components.

If the reservoir cannot supply the oil required for the cylinder stroke, the pump may draw air into the system. This can lead to erratic movement, unstable operation and potential equipment damage.

Is the QQ-700-2 Suitable for a Large Hydraulic Press?

Not necessarily. A compact 2-litre power unit may be unsuitable for hydraulic presses with large cylinders, including CraftOil’s Ukrainets oil presses, if their required oil displacement exceeds the unit’s usable oil capacity.

Before connecting the QQ-700-2 to a press or another large hydraulic cylinder, provide the cylinder specifications to CraftOil for a compatibility check.

Oil Temperature and Duty Cycle

A small reservoir has less oil available to absorb and dissipate heat than a larger tank. For this reason, the QQ-700-2 is best considered for intermittent hydraulic cycles rather than automatically assumed suitable for continuous operation throughout a full shift.

For reliable operation:

• Allow cooling breaks between demanding sequences of operations.

• Monitor oil temperature and reservoir level.

• Use the correct hydraulic oil grade specified for the unit.

• Avoid operating with insufficient oil or a system that draws air.

• Follow the manufacturer’s instructions for duty cycle and maintenance.

The right power unit depends not only on maximum pressure, but also on required oil flow, oil displacement, operating frequency and the tool’s hydraulic circuit.

Technical Specifications — CraftOil QQ-700-2

Technical specifications are based on the supplied product data. Confirm the exact configuration, control arrangement and operating requirements against the documentation for the specific unit before purchase.

Can the QQ-700-2 Run from a Generator?

Yes, provided the generator is compatible with the power unit’s electrical requirements.

The motor’s stated current draw is approximately 6 A at 220V. A generator rated at 2 kW may be a starting point for consideration, but suitability cannot be guaranteed from the nominal power rating alone. Motor starting current, generator surge capacity, voltage stability and other connected loads must also be considered.

For field operation:

• Check the generator’s continuous and starting power ratings.

• Start the power unit only when the generator is operating stably.

• Avoid running other high-load equipment from the same generator at the same time unless its capacity has been verified.

• Ensure proper electrical grounding and follow the electrical safety instructions for both devices.

This makes the QQ-700-2 a potential option for sites where a suitable mains connection is unavailable, subject to verification of the power supply.

Why Does the Pressure Gauge Read up to 1,000 Bar?

The QQ-700-2 is specified for a maximum operating pressure of 700 bar, while the supplied glycerine-filled pressure gauge has a scale extending to 1,000 bar.

The higher gauge scale does not increase the power unit’s maximum pressure. The 700 bar limit still applies, and the connected tool, cylinder, hoses, fittings and couplings must all be rated for the intended operating pressure.

Glycerine helps dampen needle vibration, making the pressure reading easier to observe in conditions where the equipment experiences vibration.

Frequently Asked Questions

What is the difference between the QQ-700 and QQ-700-2?

The QQ-700-2 is designed for dual-flow hydraulic operation and includes foot-pedal control. It can operate compatible double-acting cylinders, which require hydraulic pressure for both extension and retraction. The QQ-700 is a single-flow model and is lighter, at approximately 10 kg compared with 15 kg.

Why would I need a dual-flow hydraulic pump for field work?

A dual-flow pump can provide powered movement in both directions for a compatible double-acting cylinder. This can be useful when a cable cutter blade, puller or other tool needs controlled retraction rather than relying only on a return spring.

Will the QQ-700-2 work with my hydraulic press?

That depends on the cylinder’s oil displacement, working pressure, required flow rate and hydraulic connections. The 2-litre reservoir is intended for compact equipment; the approximate 1.5-litre working-volume figure is only a preliminary selection guideline. Contact CraftOil with your cylinder specifications before connecting the unit to a press.

Can I use the QQ-700-2 with a generator?

Potentially, yes. The stated motor current is approximately 6 A at 220V. A generator rated at 2 kW may be a starting point, but its continuous and starting power capacity, voltage stability and other connected loads must be checked.

Is the foot pedal waterproof?

The protection rating should be confirmed for the specific pedal supplied. Contact CraftOil to check its IP rating and cable length. Do not assume the pedal is suitable for rain, standing water or continuous wet-environment use without confirmation.

Can the QQ-700-2 operate continuously for a full shift?

Continuous-duty suitability should not be assumed. The compact 2-litre reservoir has limited capacity for heat dissipation, so demanding applications may require pauses and temperature monitoring. Follow the manufacturer’s duty-cycle instructions.

What hydraulic oil does the QQ-700-2 require?

The supplied product information lists ISO VG 32 or ISO VG 46 hydraulic oils and certain stated equivalents. Confirm the exact grade in the operating manual for your unit before filling the reservoir.

· Just 10 kg · 1.2 kW electric motor · 2 L oil reservoir · 700 bar maximum pressure · 220V single-phase power

The CraftOil QQ-700 compact hydraulic power unit is designed for mobile service work, installation projects and maintenance tasks where portability matters as much as hydraulic performance.

Weighing approximately 10 kg, the QQ-700 is significantly lighter than many larger hydraulic power units. Its compact design makes it easier to transport between job sites, carry into buildings and store in a service vehicle.

Despite its small size, the QQ-700 delivers a maximum operating pressure of 70 MPa (700 bar). Its two-stage hydraulic pump provides a higher flow rate at low pressure and switches to a lower flow rate as pressure rises, helping balance cylinder movement speed with high-pressure operation.

Powered by a 1.2 kW electric motor and designed for a 220V single-phase supply, the QQ-700 is intended for compatible compact hydraulic tools and equipment with suitable oil-volume requirements.

Best suited for: mobile electrical installation teams, field-service engineers, maintenance technicians and workshops that need a lightweight hydraulic power source for intermittent operations.

Why choose the QQ-700 portable hydraulic power pack?

• Lightweight design: approximately 10 kg for easier transport between work locations.

• 700 bar maximum operating pressure: suitable for compatible equipment rated for the intended pressure.

• 1.2 kW electric motor: a compact power configuration for mobile hydraulic applications.

• Two-stage hydraulic pump: higher flow at lower pressure and reduced flow at high pressure.

• Compact 2 L oil reservoir: reduces overall size and weight, with a corresponding limit on system oil-volume requirements.

• 220V single-phase supply: convenient where a suitable mains connection is available.

• Remote control: allows the operator to activate the unit without reaching directly to its housing.

• Quick-release hydraulic coupling: helps simplify connection to compatible hydraulic tools.

• Glycerine-filled pressure gauge: helps damp pointer vibration and improves readability.

• Service support in Ukraine: assistance with model selection, operation and replacement parts, subject to availability.

The QQ-700 is designed around mobility rather than maximum reservoir capacity. It is therefore important to check the oil requirements and duty cycle of your equipment before ordering.

A compact hydraulic power unit for field service

Large hydraulic power units can be difficult to move between job sites, especially where access is limited or equipment must be carried upstairs. At approximately 10 kg, the QQ-700 offers a practical alternative for applications where a smaller, portable unit is sufficient.

Where portability makes a difference

On-site electrical installation.
Transport the hydraulic power unit to compatible cable-processing tools used at installation sites and substations.

Maintenance and repair work.
Use a compact hydraulic power source for suitable service tools without moving a larger workshop unit.

Construction and installation projects.
The lightweight design can be convenient where equipment must be carried between work areas.

Restricted workspaces.
The compact format can simplify placement in workshops or service locations where floor space is limited.

Mobile service vehicles.
The unit is easier to transport and store than heavier power units, provided it is secured correctly during transit.

Portability does not remove the need for safe positioning, suitable electrical power, clean hydraulic oil and a compatible cylinder or tool.

Compact design with a 2 L oil reservoir: what you need to know

The QQ-700’s 2-litre reservoir is its main sizing limitation. The station should be selected according to the oil volume required by the connected hydraulic equipment, not pressure rating alone.

A preliminary sizing estimate is to allow an oil reserve of around 20–30%. Under that simplified assumption, a 2 L reservoir might suit a system requiring approximately 1.5 L of usable oil.

This is a preliminary estimate, not a guaranteed maximum cylinder volume. The correct selection depends on the usable reservoir capacity, the cylinder’s geometry and stroke, the oil needed in each working chamber, the return arrangement and the manufacturer’s filling requirements.

Comparing reservoir capacities

These are preliminary estimates based on an assumed 20–30% reserve. They are not certified cylinder-volume limits or substitutes for the manufacturer’s sizing instructions.

What happens if the reservoir is too small?

If the hydraulic system requires more oil than the power unit can safely supply, the oil level may fall below the required level during operation. This can cause air to enter the system, unstable pressure, jerky cylinder movement and potential equipment damage.

Before connecting a cylinder, confirm the required oil volume and the manufacturer’s minimum operating level.

The QQ-700 is intended for compact hydraulic tools and smaller systems. A large cylinder or press may require a power unit with a larger reservoir.

Need to power a larger hydraulic cylinder? Contact CraftOil with your equipment model, cylinder stroke and oil-volume requirements. We can help you assess whether a 7 L, 10 L or 30 L reservoir would be more suitable.

Thermal considerations: designed for intermittent operation

A small oil reservoir offers a weight advantage, but it also contains less oil to absorb and distribute heat generated during hydraulic operation.

The QQ-700 is best considered for intermittent operating cycles rather than assumed continuous-duty production. The appropriate duty cycle depends on operating pressure, cycle frequency, ambient temperature and the connected equipment.

For safer operation:

• Monitor oil temperature during repeated cycles.

• Follow the manufacturer’s temperature and duty-cycle limits.

• Allow cooling pauses when required.

• Check the oil level regularly.

• Stop operation if the unit shows abnormal heating, noise or unstable hydraulic movement.

For long production shifts or frequent heavy-load operation, a larger power unit may be a better choice. A larger reservoir can provide more oil capacity, although continuous-duty suitability still needs to be assessed against the actual workload and cooling arrangements.

Can the QQ-700 run from a generator?

The supplied specifications state that the QQ-700 has a 1.2 kW motor and an approximate operating current of 6 A. This makes generator operation a potential option for field work where mains power is unavailable.

A generator rated at 2 kW or more may be a starting point for assessment, but rated wattage alone does not guarantee compatibility. The generator must support the motor’s starting current, the actual electrical load and any other connected equipment.

Before use:

• Check the motor nameplate and generator specifications.

• Confirm the generator’s continuous output and surge capacity.

• Start and stabilise the generator according to its manufacturer’s instructions before activating the hydraulic unit.

• Avoid overloading the generator with other consumers.

• Follow the grounding and electrical-safety requirements for the generator and work site.

For reliable operation, confirm the generator’s suitability with its manufacturer or a qualified electrician.

220V power supply

The QQ-700 is specified for a 220V single-phase supply. Its stated approximate current is 6 A, although actual current can vary with motor characteristics and operating conditions.

A suitable mains connection may be convenient for mobile service work, but check the following before use:

• The supply voltage and frequency match the motor nameplate.

• The socket, cable and protective devices are suitable for the motor.

• Extension leads are correctly rated and fully uncoiled where required.

• Electrical grounding and protection meet local requirements.

• Cables are kept away from water, sharp edges and moving machinery.

Do not assume that every household socket or portable generator is suitable without checking the equipment requirements.

Technical specifications

Specifications are based on the supplied product information. Confirm the exact control arrangement, flow rates and electrical requirements for the current production batch before purchase.

Understanding the two-stage hydraulic pump

The QQ-700 uses a two-stage pump to provide different flow rates at different pressure levels.

First stage: 5 L/min

At lower pressure, the pump delivers a higher flow rate, allowing a compatible cylinder to move more quickly when resistance is relatively low.

Second stage: 0.7 L/min

At high pressure, the pump operates at a lower flow rate to develop the force required for demanding hydraulic operations.

The high-pressure flow rate specified for the QQ-700 is lower than that listed for some larger power units. This is part of the model’s compact configuration and should be considered when comparing expected cycle times.

Actual flow and movement speed depend on operating pressure, cylinder displacement, load and the hydraulic circuit.

Pressure gauge: 1000 bar scale, 700 bar maximum pressure

The QQ-700 is supplied with a glycerine-filled pressure gauge with a scale extending to 1000 bar. The power unit’s maximum operating pressure remains 700 bar.

A gauge with a scale above the unit’s operating limit does not increase the pressure rating of the pump, hoses, cylinder or connected tool.

Glycerine filling helps reduce pointer oscillations caused by vibration, making pressure readings easier to observe in many working environments.

Always operate within the lowest pressure rating of all connected hydraulic components.

Package contents

The supplied package includes:

• CraftOil QQ-700 hydraulic power unit

• 2 m high-pressure hydraulic hose

• Quick-release hydraulic coupling

• Glycerine-filled pressure gauge, 0–1000 bar scale

• Pressure-gauge adapter

• Remote control

• Operating instructions

• Factory packaging

Hydraulic oil is not included. The reservoir capacity is 2 L. Use the manufacturer’s filling instructions to determine the correct filling quantity and oil level.

Confirm the supplied coupling type and compatibility with your hydraulic tool before ordering.

Compatible applications

The QQ-700 may be suitable for compact hydraulic tools that meet its pressure, flow, oil-volume and connection requirements.

Potential applications include:

• Cable lug and terminal crimping tools

• Hydraulic cable cutters

• Hydraulic punching tools

• Bearing and pulley pullers

• Small hydraulic cylinders

• Compact hydraulic presses

• Compatible busbar bending tools

• Other hydraulic tools with suitable oil-volume requirements and a maximum working pressure within the unit’s rating

Compatibility must be verified for each tool. A tool’s pressure rating alone is not enough to establish suitability. Its cylinder displacement, oil demand, return arrangement, required flow and hydraulic connections must also match the power unit.

Is the QQ-700 suitable for a CraftOil hydraulic press?

Not every hydraulic press is suitable for this compact power unit. For example, a press with a large cylinder may require substantially more oil than a 2 L reservoir can safely supply.

Before connecting the QQ-700 to a CraftOil press, provide the press model and cylinder specifications. CraftOil can help assess the required pressure, flow rate and oil volume and advise whether a larger power unit is necessary.

Who should choose the QQ-700?

This compact hydraulic power unit is worth considering for:

• Mobile electrical installation teams

• Field-service engineers

• Maintenance technicians

• Installation crews working at substations and construction sites

• Workshops with occasional hydraulic tasks

• Users who need to transport equipment frequently

• Operators using compact tools with modest oil-volume requirements

When is a larger hydraulic power unit a better choice?

Consider a larger reservoir and a different pump configuration if:

• Your cylinder requires more oil than the QQ-700 can safely supply.

• You operate a large hydraulic press.

• Your production involves frequent, sustained hydraulic cycles.

• Your application requires a higher high-pressure flow rate.

• The equipment manufacturer specifies a larger reservoir or different pump characteristics.

The QQ-700 prioritises low weight and portability. It should not be selected simply because it has a 700 bar pressure rating.

Compare CraftOil hydraulic power units

The table below compares the supplied specifications for several CraftOil power-unit models.

Oil-volume figures are preliminary estimates, not guaranteed equipment compatibility limits. Verify each model’s specifications and intended hydraulic circuit before ordering.

Three questions to choose the right model

1. How much oil does your hydraulic tool require?
The QQ-700 has a 2 L reservoir. If your system requires more usable oil than the unit can safely supply, consider a larger model.

2. Will you transport the power unit frequently?
If portability is essential, the QQ-700’s approximate 10 kg weight is a significant advantage. For a stationary workshop, a heavier unit with a larger reservoir may be more appropriate.

3. Is the work intermittent or continuous?
The QQ-700 is best considered for intermittent work within the manufacturer’s limits. For sustained production, assess a larger reservoir and a power unit designed for the intended duty cycle.

Recommended hydraulic oil

Use an industrial hydraulic oil that meets the power unit manufacturer’s requirements.

The supplied product information lists ISO VG 32 and ISO VG 46 hydraulic oils as possible options, including compatible HLP 32/HLP 46 products and equivalents. Products such as I-20A or MGE-46V should only be used if their suitability is confirmed against the equipment manual and operating conditions.

Oil maintenance for mobile hydraulic equipment

• Oil grade: follow the manufacturer’s manual and operating-temperature requirements.

• Filling quantity: the reservoir capacity is 2 L; the actual filling quantity must follow the specified oil level.

• Oil cleanliness: use clean filling equipment and suitable filtration.

• Dust protection: avoid leaving the filling port open in dusty work areas.

• Oil-level checks: inspect the level regularly, especially when using the unit in the field.

• Temperature: monitor heating during repeated cycles and observe the manufacturer’s limits.

• Oil changes: follow the recommended maintenance schedule and inspect the oil for contamination, abnormal darkening or a burnt smell.

• Mixing oils: do not mix different products unless compatibility has been confirmed.

Because the reservoir is small, a modest oil loss or contamination can have a noticeable effect. Carrying a sealed container of the correct hydraulic oil may be useful for field-service work.

Transport and storage tips

To help protect the QQ-700 between job sites:

• Transport and store the unit in the orientation specified by the manufacturer.

• Secure the unit in the vehicle so it cannot tip over or move during transit.

• Ensure the filling cap is properly secured.

• Keep the hydraulic hose in a loose loop and avoid sharp bends.

• Protect couplings from dust and dirt.

• Place the power unit on a stable, level surface during operation.

• Keep the unit away from loose soil, sand and other contaminants.

• Check the oil level and inspect the hose and connections before starting work.

Always follow the manufacturer’s instructions for transporting the unit and preventing oil leakage.

Safety and operation

High-pressure hydraulic equipment must be used by trained personnel.

• Inspect the hydraulic hose before every use. Replace it if cracks, bulges, leaks or other damage are found.

• Never exceed the pressure rating of the power unit or connected equipment.

• Never disconnect a quick-release coupling while the hydraulic system is pressurised.

• Wear suitable eye protection and follow the tool manufacturer’s safety instructions.

• Keep hands clear of moving components and pinch points.

• Place the power unit on a stable surface, away from dust and loose debris.

• Monitor oil temperature during repeated operations and allow cooling pauses when required.

• Ensure the power supply or generator is suitable for the motor.

• Follow all grounding and electrical-safety requirements.

• Isolate the electrical supply and release hydraulic pressure before maintenance.

Important: 700 bar is the power unit’s maximum stated operating pressure, not a guarantee that every connected tool, cylinder, hose or fitting can withstand that pressure.

Frequently Asked Questions

1. How much does the QQ-700 hydraulic power unit weigh?

The supplied specification lists an approximate weight of 10 kg, making it suitable for applications where portability is important.

2. What is the maximum operating pressure?

The QQ-700 is rated for a maximum operating pressure of 70 MPa, equivalent to 700 bar. Its pressure gauge has a scale up to 1000 bar, but this does not increase the unit’s pressure rating.

3. What is the oil reservoir capacity?

The reservoir capacity is 2 L. The suitable cylinder or tool must be selected according to the usable oil capacity and the manufacturer’s operating requirements.

4. What size hydraulic cylinder can it operate?

There is no universal cylinder-size limit based on reservoir capacity alone. As a preliminary estimate, a 2 L reservoir may suit a system requiring approximately 1.5 L of usable oil, but the actual compatibility depends on the cylinder’s geometry, stroke, oil requirements and system configuration.

5. Can the QQ-700 run from a generator?

Potentially, yes. The supplied information lists a 1.2 kW motor with an approximate operating current of 6 A. A generator rated at 2 kW or more may be a starting point, but its continuous output and motor-starting capability must be checked before use.

6. Can I use the QQ-700 throughout an entire production shift?

The model is best considered for intermittent operation within the manufacturer’s limits. Its small reservoir has less capacity to absorb and distribute heat than larger tanks. For sustained production, assess a larger power unit.

7. What are the pump flow rates?

The supplied specifications list 5 L/min at the first stage and 0.7 L/min at the second stage. Confirm these values against the current product specification before ordering.

8. Which hydraulic oil should I use?

The supplied information lists ISO VG 32 and ISO VG 46 hydraulic oils as possible options. Follow the manufacturer’s manual to confirm the correct grade for the operating conditions.

· 14 L/min first-stage flow · 2.8 L/min high-pressure flow · 30 L oil reservoir · 700 bar maximum pressure · 220V single-phase power supply

The CraftOil 3 kW double-acting hydraulic power unit with foot-pedal control is designed for demanding workshop and industrial applications where efficient hydraulic movement, repeatable operation and convenient operator control are important.

Powered by a 3 kW electric motor, this hydraulic power pack features a two-stage pump, a 30-litre oil reservoir and an electromagnetic directional valve operated by a foot pedal. Its double-acting hydraulic circuit supplies oil alternately to ports A and B, allowing compatible hydraulic cylinders to extend and retract under hydraulic pressure.

With a maximum operating pressure of 70 MPa (700 bar), a first-stage flow rate of 14 L/min and a high-pressure flow rate of 2.8 L/min, this model is suitable for compatible hydraulic equipment used in cable processing, metalworking, industrial maintenance and repetitive production operations.

The foot pedal allows the operator to activate the hydraulic system while keeping both hands available for positioning or supporting the workpiece.

CraftOil provides equipment selection assistance, service support in Ukraine and delivery arrangements for domestic and international customers.

Why choose the CraftOil 3 kW hydraulic power pack?

• Powerful 3 kW electric motor: designed for demanding hydraulic applications and repetitive work cycles.

• High first-stage flow rate: 14 L/min for faster cylinder movement when operating conditions allow.

• 2.8 L/min high-pressure flow: supports hydraulic movement under higher resistance.

• Double-acting hydraulic circuit: enables powered extension and retraction of compatible cylinders.

• Foot-pedal control: keeps the operator’s hands available for positioning the workpiece.

• 30 L oil reservoir: provides substantial oil capacity for compatible hydraulic systems.

• 700 bar maximum operating pressure: for equipment rated to work within this pressure limit.

• Two-stage hydraulic pump: combines higher flow at lower pressure with lower flow at high pressure.

• Glycerine-filled pressure gauge: helps reduce pointer vibration for easier pressure monitoring.

• 220V single-phase motor configuration: requires an electrical supply designed for the motor’s actual current and starting requirements.

This configuration is worth considering for production environments where hydraulic equipment operates repeatedly throughout a shift. Actual productivity depends on the cylinder, load, required pressure, cycle sequence and operating conditions.

How the 3 kW motor, double-acting circuit and foot pedal improve workflow

Each part of this hydraulic power unit addresses a different aspect of the work process.

The combined effect can be useful in repetitive production, but no single specification guarantees a particular cycle time. The final result depends on the connected equipment and the actual working sequence.

Foot-pedal control for repetitive industrial operations

The foot pedal operates the electromagnetic directional valve, allowing the operator to activate the hydraulic system without reaching for a manual control lever.

This is particularly useful when both hands are needed to hold a cable terminal, position a die or support a workpiece.

Key advantages

Hands remain available for positioning.
The operator can hold or align a component while controlling the hydraulic movement with a foot.

Fewer repeated hand movements.
The operator does not need to move between the work area and a manual lever for every cycle.

Convenient for repetitive production.
Foot control can improve workflow when the same hydraulic operation is performed many times during a shift.

Potentially more consistent positioning.
Keeping the workpiece supported during activation can help reduce unwanted movement.

Electromagnetic valve control.
The directional valve is activated electrically through the foot pedal rather than by manually moving a lever.

Important: train operators to work at the correct speed

The 3 kW configuration can deliver higher flow than smaller power units. Depending on the cylinder and load, the piston rod may move faster during the low-pressure stage.

Operators should become familiar with the movement speed before starting production. For precise positioning, use controlled pedal inputs where the equipment design permits, and follow the machine manufacturer’s operating instructions.

• Begin with supervised test cycles.

• Keep hands clear of pinch points and moving parts.

• Confirm that the workpiece and tooling are securely positioned.

• Make sure the pedal cannot be activated accidentally.

• Train new operators before allowing routine production work.

The purpose of this guidance is to help users operate the equipment confidently and safely, not to suggest that the foot pedal alone guarantees greater accuracy.

Double-acting hydraulic circuit: powered extension and retraction

The unit has two working hydraulic lines, designated A and B. The directional valve switches the oil supply between the two working chambers of a compatible hydraulic cylinder.

• Extension: oil is directed to the appropriate cylinder chamber to extend the piston rod.

• Retraction: the valve switches the oil supply to the other chamber, allowing the rod to retract under hydraulic pressure.

• Controlled movement in both directions: the cylinder does not have to rely solely on a return spring or gravity for its return stroke.

The actual direction of movement depends on the cylinder design and the hose connections.

How do you know whether you need a double-acting power unit?

A double-acting hydraulic power unit may be required when:

• The cylinder is designed with two hydraulic working ports.

• The piston rod must retract under hydraulic pressure.

• The connected machine requires powered movement in both directions.

• The application involves a controlled return stroke under load.

• The equipment manufacturer specifies a double-acting hydraulic circuit.

Check compatibility before connecting the hoses. Two ports can be a useful initial indication, but the cylinder documentation must confirm the port functions and required hydraulic circuit.

Technical specifications

The values above are based on the supplied product information. Confirm the precise configuration, electrical requirements and connections before purchase.

Two-stage pump: high flow and high pressure

The two-stage pump operates with different flow rates depending on the pressure required by the hydraulic system.

First stage: 14 L/min

At relatively low pressure, the pump provides a higher flow rate to move the cylinder more quickly when resistance is low.

Second stage: 2.8 L/min

As pressure increases, the pump switches to a lower flow rate to develop the force required for more demanding operations.

This design balances faster movement at lower pressure with the ability to perform high-pressure hydraulic work.

Example: filling a 0.5 L cylinder chamber

At a theoretical flow rate of 2.8 L/min, delivering 0.5 litres of oil would take approximately 11 seconds.

For comparison, a flow rate of 1.7 L/min would require approximately 18 seconds for the same theoretical volume.

These are simplified calculations, not guaranteed cycle times. Actual movement time depends on the operating pressure, pump behaviour, cylinder geometry, hose restrictions and other system characteristics.

30 L oil reservoir: capacity and thermal considerations

The 30-litre reservoir provides substantial oil capacity, but reservoir size must be matched to the complete hydraulic system and its duty cycle.

Two separate factors should be considered.

1. Required oil volume

The reservoir must contain enough usable oil to supply the cylinder throughout its working stroke while maintaining the oil level required by the manufacturer.

As a preliminary estimate, a reserve of 20–30% may be useful when assessing the relationship between reservoir capacity and system oil volume. This is not a universal sizing rule or a guaranteed cylinder-volume limit. For a double-acting cylinder, calculate the oil requirements for both chambers and account for the piston rod, stroke length and system layout.

2. Heat generated during operation

During repeated hydraulic cycles, some input energy is converted into heat. A 30 L reservoir should not automatically be assumed suitable for every continuous-duty application at a pump flow of 14 L/min.

For intensive or prolonged operation, assess the duty cycle, operating pressure, ambient temperature and cooling requirements. Monitor oil temperature and follow the manufacturer’s limits. Depending on the application, scheduled pauses or additional cooling may be necessary.

For continuous production: contact CraftOil with your cycle rate and cylinder specifications so the power unit can be assessed for your actual operating conditions.

220V electrical supply: installation requirements

The 3 kW motor requires more electrical capacity than a typical smaller hydraulic power unit.

At 220V, the motor may draw approximately 15–18 A under the assumptions supplied, with a higher current possible during startup. Actual current depends on the motor’s nameplate, efficiency, power factor and operating conditions.

For this reason, do not assume that every standard socket or extension lead is suitable.
