CraftOil DB075-D2 Double-Acting Hydraulic Power Unit with Foot Pedal

Description

CraftOil DB075-D2 Double-Acting Hydraulic Power Unit with Foot Pedal

Hands-free positioning. Electromagnetic hydraulic control. High-pressure performance for repetitive operations.

The CraftOil DB075-D2 is a double-acting electric hydraulic power unit designed for applications where the operator needs to keep both hands available to position and hold a workpiece.

Instead of operating a manual directional-valve lever, the operator controls the hydraulic function using a foot pedal connected to an electromagnetic valve system. This arrangement is particularly useful for repetitive operations such as cable lug crimping, where accurate workpiece positioning and consistent operating procedures matter.

The unit combines a two-stage hydraulic pump, a 0.75 kW electric motor, a 7-litre oil reservoir and a double-acting hydraulic circuit. It is designed for a 220 V single-phase electrical supply and has a specified maximum operating pressure of 70 MPa (700 bar).

The DB075-D2 is a practical choice for electrical installation teams, cable-processing workshops and production areas where similar hydraulic operations are repeated throughout the working day.

CraftOil provides technical assistance and spare-parts support in Ukraine.

Key Benefits of the DB075-D2

• Foot pedal control: allows the operator to control the hydraulic function while keeping both hands available for the workpiece and tooling.

• Electromagnetic directional valve: switches the hydraulic flow without requiring manual operation of a valve lever.

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

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

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

• 0.75 kW electric motor: designed for applications compatible with the unit’s specified flow and power.

• 7 L oil reservoir: suitable for compatible hydraulic circuits within the tank’s usable oil capacity.

• 220 V single-phase supply: designed for connection to a suitable electrical outlet and circuit.

• Glycerine-filled pressure gauge: helps dampen needle vibration and improve readability.

• Service support in Ukraine: assistance with troubleshooting and replacement components, subject to availability.

Why Choose a Foot-Pedal Hydraulic Power Unit?

During repetitive work, an operator may need to hold a cable, position a connector and align the tooling before starting the hydraulic stroke. With a manually operated directional valve, the operator may need to move a hand away from the work area to operate the control.

The DB075-D2 uses a foot pedal for hydraulic control, helping keep both hands available for positioning the workpiece.

Practical Advantages

1. Improved workpiece positioning

The operator can maintain a grip on the cable or component while initiating the hydraulic operation. This can help reduce unwanted movement between positioning and the start of the stroke.

2. More efficient repetitive operations

The foot pedal removes the need to reach for a manual valve lever during each cycle. The actual time saved depends on the work process, tooling and operator technique.

3. Convenient operation for cable processing

The configuration is particularly relevant to cable lug crimping and similar repetitive operations where accurate positioning is important.

4. Electromagnetic valve actuation

The directional valve is operated electromagnetically rather than by a manually moved lever. This changes the control method, although overall system response still depends on the hydraulic circuit and connected equipment.

An Honest Note About the Trade-Offs

The DB075-D2 weighs 32 kg, compared with approximately 25 kg for the specified manually operated models with similar hydraulic performance.

The additional weight reflects the electromagnetic control arrangement. The pedal, cable and solenoid valve also introduce electrical components that require inspection and maintenance.

The pedal should be positioned to prevent accidental activation, and its cable must be routed away from walkways and moving equipment.

Our recommendation: if you perform repetitive operations in batches and need both hands available to position the workpiece, the DB075-D2 is worth considering. For occasional operations, a manual-valve model such as the HHB-700AB may be a more economical choice.

Double-Acting Hydraulic Circuit

The DB075-D2 is designed for compatible double-acting hydraulic cylinders.

A double-acting cylinder uses two hydraulic ports. Oil is directed alternately to the piston side and rod side, allowing controlled movement in both directions.

The unit’s two working lines, A and B, support hydraulic extension and retraction through a compatible directional-valve arrangement.

When Do You Need a Double-Acting Hydraulic Power Unit?

Choose a double-acting power unit when:

• Your cylinder requires hydraulic connections to both working chambers.

• The rod must retract under hydraulic pressure rather than relying only on a spring or gravity.

• You need controlled movement in both directions.

• Your equipment requires a powered return stroke.

• You operate compatible hydraulic presses, pipe benders, pullers or other double-acting machinery.

Quick compatibility check: two hydraulic ports often indicate a double-acting cylinder, but the port count alone is not conclusive. Confirm the cylinder type, connection functions, pressure rating and required valve configuration in the equipment documentation.

If you are unsure, send CraftOil a photograph of the cylinder, its identification plate and its hydraulic connections. We can help you assess compatibility before purchase.

Technical Specifications

Confirm the product nameplate and manual for the exact electrical, hydraulic and installation requirements.

Hydraulic Flow Rate and Working Cycle

The DB075-D2 uses a two-stage pump with the following specified delivery rates:

• First stage: 5 L/min at a stated pressure of 2 MPa.

• High-pressure stage: 0.9 L/min at a stated pressure of 70 MPa.

The first stage provides a higher flow rate at lower pressure. At the high-pressure stage, the flow rate is lower, supporting operation at the specified maximum pressure.

For a theoretical comparison, delivering 0.5 litres at 0.9 L/min takes approximately 33 seconds, while delivering 1 litre takes approximately 67 seconds.

These are calculated estimates, not guaranteed machine-cycle times. Actual cylinder movement depends on operating pressure, effective chamber volume, cylinder dimensions, hydraulic losses and the connected equipment.

For applications where speed is the primary requirement, discuss the cylinder volume and expected cycle frequency with CraftOil before choosing a power unit.

220 V Electrical Supply

The DB075-D2 has a 0.75 kW motor and is specified for a 220 V single-phase supply.

Compared with higher-powered hydraulic power units, this motor has lower power requirements. Nevertheless, the electrical installation must be suitable for the motor and the electromagnetic control circuit.

Before operation:

• Confirm the supply voltage and electrical rating on the product nameplate.

• Use a properly maintained socket and suitable circuit protection.

• Ensure protective earthing is provided as required.

• Inspect the power cable and foot-pedal cable for damage.

• Keep electrical connections away from hydraulic oil and areas where cables could be crushed or tripped over.

• Follow the manufacturer’s instructions for connection and commissioning.

Do not operate the unit if electrical components, cables or connectors are damaged.

7 L Hydraulic Oil Reservoir: What You Need to Know

The DB075-D2 has a nominal reservoir capacity of 7 litres.

As a preliminary sizing guideline, the available oil volume should exceed the required working oil volume of the connected hydraulic equipment by approximately 20–30%, subject to the circuit design and manufacturer’s instructions.

A 7 L reservoir may therefore be suitable for certain hydraulic systems with a working oil requirement of approximately 5.5 litres. This is an indicative estimate, not a universal maximum cylinder volume.

For a double-acting cylinder, account for the effective oil volume required by both chambers and the complete operating cycle. Also follow the manufacturer’s permitted fill level and minimum operating level.

If your equipment requires a larger oil volume, consider a power unit with a 10 L or 30 L reservoir, subject to compatibility with the required pressure, flow and control arrangement.

Pressure Gauge: 1,000 Bar Scale, 700 Bar Maximum Operating Pressure

The supplied glycerine-filled pressure gauge has a scale extending to 1,000 bar. The specified maximum operating pressure of the DB075-D2 remains 700 bar.

These are two different specifications:

• 700 bar is the maximum operating pressure specified for the power unit.

• 1,000 bar is the upper limit of the pressure gauge’s scale.

A gauge with a higher scale limit does not increase the pressure rating of the hydraulic power unit.

Glycerine helps dampen needle vibration, which can improve readability in systems with pressure pulsation. Always ensure that the cylinder, hoses, fittings, valves and other connected components are rated for the intended pressure.

The pressure rating of the lowest-rated component must never be exceeded.

Recommended Hydraulic Oil

The exact hydraulic oil specification must be confirmed in the product manual.

The source information indicates industrial hydraulic oils in the ISO VG 32 or ISO VG 46 viscosity classes, including compatible HLP 32/HLP 46 products and approved equivalents. Suitability depends on the equipment requirements and operating conditions.

Recommended practices:

• Confirm the oil grade: follow the manufacturer’s instructions.

• Maintain oil cleanliness: use suitable filtration when filling the reservoir.

• Prevent contamination: clean oil is especially important for the pump and electromagnetic directional valve.

• Check the oil level: follow the specified operating and filling levels.

• Monitor oil condition: inspect the oil and replace it according to the manual and actual operating conditions.

• Avoid mixing oils: confirm compatibility before changing oil type or manufacturer.

Contaminated oil can contribute to pump wear and may cause the directional-valve spool to stick, affecting hydraulic control.

Contact CraftOil if you need help identifying the appropriate hydraulic oil for your operating conditions.

Safety and Operation

The DB075-D2 combines high-pressure hydraulics with electrical foot-pedal control. Correct installation and safe operating procedures are essential.

• Position the foot pedal to prevent accidental activation.

• Route the pedal cable away from walkways, moving equipment and areas where it could be crushed.

• Before work begins, verify that the pedal and control system operate predictably, following the manufacturer’s commissioning instructions.

• Inspect the hydraulic hose and fittings before each use. Replace damaged, cracked, swollen or leaking components.

• Confirm that lines A and B are connected to the correct ports.

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

• Never exceed the rated pressure of the power unit, hoses, cylinder, valves or fittings.

• Never use your hands to locate a high-pressure oil leak. High-pressure fluid injection injuries can be severe.

• Wear suitable eye protection and follow the connected equipment’s operating instructions.

• Ensure proper electrical protection and protective earthing.

• Isolate the power supply and depressurise the hydraulic system according to the manual before maintenance.

The gauge’s 1,000 bar scale does not permit the power unit to operate above its specified 700 bar maximum.
