· In stock in Kharkiv, Ukraine · Warranty and service in Ukraine · Same-day dispatch when available in stock

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.
