Description

HHB-700D3 Three-Outlet Hydraulic Power Unit with Foot Pedal

· 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

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.
