CraftOil QQ-700 Compact Hydraulic Power Unit — 700 Bar

Description

CraftOil QQ-700 Compact Hydraulic Power Unit — 700 Bar

· 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:

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.
