· 700 bar working pressure · 1.5 kW electric motor · 10 L oil reservoir · 220V power supply · Foot-pedal control

The CraftOil DB150-D2 double-acting hydraulic power unit is designed for repetitive industrial operations where controlled movement, convenient hands-free activation and reliable hydraulic performance are essential.

Equipped with a 1.5 kW electric motor, a two-stage hydraulic pump and an electromagnetic directional valve operated by a foot pedal, this hydraulic power pack supplies oil to both working ports of a compatible double-acting hydraulic cylinder. The cylinder can extend and retract under hydraulic pressure, providing controlled movement in both directions.

With a maximum operating pressure of 70 MPa (700 bar), a 10-litre oil reservoir and a 220V single-phase power supply, the DB150-D2 is suitable for workshops, electrical installation companies, production lines and industrial maintenance operations using compatible high-pressure hydraulic equipment.

Available from CraftOil: stock and dispatch options from Kharkiv, Ukraine, technical consultation and service support.

Why choose the DB150-D2 hydraulic power pack?

• Foot-pedal operation: activate the hydraulic system without moving your hand to a manual control lever.

• Double-acting hydraulic circuit: pressure is supplied alternately to ports A and B for powered extension and retraction of compatible cylinders.

• 1.5 kW electric motor: designed for demanding and repetitive hydraulic operations.

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

• 700 bar maximum operating pressure: suitable for equipment specifically rated for this pressure.

• 10 L oil reservoir: designed for hydraulic systems whose oil-volume requirements are compatible with the station.

• 220V single-phase supply: convenient for many workshop installations, subject to the electrical requirements of the unit.

• Glycerine-filled pressure gauge: helps reduce pointer vibration and makes pressure readings easier to observe.

• Parts and service support in Ukraine: assistance with troubleshooting, replacement components and setup.

Why use a foot pedal instead of a manual lever?

In repetitive production work, the time required to operate the hydraulic system is only part of the overall cycle. The operator also needs to position the workpiece, move their hand to the control and return their hand to the working area.

The DB150-D2 uses a foot pedal with electromagnetic valve control, allowing the operator to activate the hydraulic system while keeping both hands available for positioning or supporting the workpiece.

This can be particularly useful when working with cable crimping tools, hydraulic presses and other equipment where accurate positioning is important.

Key advantages of foot-pedal control

Hands remain available for the workpiece.
The operator can hold or position the component while activating the hydraulic movement with a foot pedal.

Convenient for repetitive operations.
Reducing repeated hand movements between the work area and the control lever can make the workflow more convenient over a long shift.

Consistent positioning.
Keeping the workpiece in position during activation can help reduce unwanted movement between cycles.

Reduced repetitive hand movements.
Foot control can improve operator convenience when the same operation is repeated many times.

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

Is a foot pedal worth the extra cost?

For production environments with frequent, repetitive operations, foot-pedal control can improve workflow and operator convenience. The actual time savings depend on the workpiece, the cycle sequence, the operator and the machine layout; they should be evaluated under real operating conditions.

There is also a trade-off: an electromagnetic valve and foot-pedal assembly introduce additional electrical components that may require troubleshooting or replacement. A manual-lever version can be a more economical choice for occasional work.

Alternative: If you need the same basic hydraulic configuration but prefer manual control, consider the CraftOil DB150-S2, subject to confirmation of the required connections and specifications.

Double-acting hydraulic circuit: how it works

The DB150-D2 has two working hydraulic lines, designated A and B. The directional valve switches the oil supply between the cylinder’s two working chambers.

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

• Retraction: the valve switches the hydraulic flow so the piston rod retracts under hydraulic pressure.

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

The actual direction of movement depends on the cylinder design and the way the hoses are connected.

When do you need a double-acting hydraulic power unit?

Choose a double-acting power unit when:

• The hydraulic cylinder has two working ports.

• The piston rod must retract under hydraulic pressure or against a load.

• Both extension and retraction need to be controlled hydraulically.

• The connected machine requires a powered return stroke.

• You operate compatible hydraulic presses, pipe benders, pullers or industrial tooling.

Important: Two ports are a useful initial indication, but always check the cylinder documentation and port functions before connecting the power unit. A double-acting pump must be compatible with the hydraulic cylinder, valve arrangement, pressure rating and hose connections.

Technical specifications

Specifications are based on the supplied product information. Confirm the exact configuration, connections and electrical requirements before ordering.

Understanding the two-stage pump

A two-stage hydraulic pump provides different flow rates according to operating pressure.

At lower pressure, the pump delivers a higher flow rate of 7.9 L/min, helping the cylinder move more quickly when resistance is relatively low. At higher pressure, the pump switches to a lower flow rate of 1.7 L/min, allowing the system to develop the required pressure for demanding operations.

This operating principle balances faster movement at low pressure with the force required for high-pressure work.

Actual cycle time depends on cylinder displacement, load, pressure, hose configuration and the operating characteristics of the connected equipment.

Is the 10-litre oil reservoir sufficient?

The DB150-D2 is equipped with a 10-litre oil reservoir. Whether this capacity is sufficient depends on the connected cylinder and the complete hydraulic circuit.

As a preliminary sizing guideline, allowing a reserve of approximately 20–30% may be useful. Under that simplified assumption, a 10-litre reservoir may suit a system requiring around 7–8 litres of usable oil. This is an estimate, not a universal compatibility limit.

For a double-acting cylinder, the required oil volume must be calculated for both directions of movement, taking account of the cylinder’s piston and rod areas, stroke length and the manufacturer’s reservoir-filling requirements.

For larger hydraulic systems or equipment with greater oil-volume requirements, ask CraftOil about a power unit with a larger reservoir, such as a 30-litre configuration.

220V power supply and installation

The DB150-D2 is designed for a 220V single-phase supply. Its 1.5 kW motor draws approximately 7 A under the stated operating assumptions, although actual current depends on the motor and operating conditions.

For safe installation:

• Check the motor nameplate and manufacturer’s electrical requirements.

• Use a properly grounded power supply and suitable circuit protection.

• Avoid undersized extension leads and extension cables left tightly coiled during operation.

• Keep the power cable and foot-pedal cable away from walkways and moving parts.

• Have the installation checked by a qualified electrician when necessary.

Do not select a cable, socket or circuit breaker solely on the basis of the nominal motor power.

Pressure gauge: 1000 bar scale, 700 bar maximum pressure

The supplied glycerine-filled pressure gauge has a scale extending to 1000 bar. The maximum operating pressure of the DB150-D2 remains 700 bar.

The higher gauge scale does not increase the pressure capability of the power unit or the connected equipment. The pressure gauge and hydraulic components must be used within their specified operating limits.

Glycerine filling helps damp pointer oscillations caused by vibration, making the pressure easier to read in many working environments.

Compatibility depends on the equipment’s required pressure, flow rate, oil volume, cylinder type, hydraulic connections and electrical requirements. A maximum pressure rating of 700 bar does not mean that every listed machine can safely operate at 700 bar.

Who is the DB150-D2 best suited for?

This model is worth considering for:

• Electrical installation companies performing repetitive cable-crimping operations

• Cable-processing workshops

• Production departments with repeated hydraulic cycles

• Industrial maintenance teams

• Workshops where the operator needs to hold or position a component while activating the hydraulic system

For occasional operations, a manual-lever power unit may be sufficient. For more intensive work, the full operating cycle, oil temperature, electrical supply and reservoir capacity should be assessed before choosing the station.

How to choose the right CraftOil DB-series power unit

The DB-series model codes help distinguish motor power, control method and hydraulic circuit configuration.

• DB075 / DB150: identifies the 0.75 kW or 1.5 kW motor configuration in the models listed below.

• S: manual directional-valve control.

• D: electromagnetic control with a foot pedal.

• 1: single-acting hydraulic circuit.

• 2: double-acting hydraulic circuit.

These conventions describe the supplied models; confirm the complete model designation and specification sheet when ordering.

DB-series comparison

Three questions to help select a model

1. How many working ports does the cylinder have?
Check the cylinder documentation. If it requires hydraulic pressure for both extension and retraction, select a compatible double-acting power unit.

2. Does the operator need both hands available during the cycle?
If yes, foot-pedal control may be beneficial. If not, a manual-lever model may offer better value for occasional work.

3. How much oil does the complete system require?
Compare the cylinder displacement and system oil volume with the usable reservoir capacity. For systems requiring more oil, consider a larger reservoir.

Compatibility with CraftOil hydraulic presses

CraftOil manufactures hydraulic presses in 50-tonne and 70-tonne configurations and has practical experience with hydraulic equipment in its own workshop.

However, selecting a power unit for a press requires more than comparing tonnage. The cylinder’s required pressure and flow rate, displacement, return method, hydraulic connections and duty cycle must all be compatible.

Before purchasing, provide CraftOil with the following information:

• Equipment or press model

• Cylinder type and number of working ports

• Required operating pressure

• Cylinder stroke and displacement, if known

• Number of cycles per shift

• Intended installation location and power supply

The CraftOil team can help assess whether the DB150-D2 is suitable or whether another power unit would be a better choice.

Recommended hydraulic oil

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

The supplied product information lists industrial hydraulic oils in viscosity grades ISO VG 32 or ISO VG 46, including compatible HLP 32/HLP 46 products and other equivalents. Examples such as I-20A or MGE-46V should only be used if their properties and suitability are confirmed against the equipment manual and operating temperature.

Oil selection and maintenance guidelines:

• Follow the manufacturer’s manual for the approved oil grade and filling level.

• Keep the oil clean; contamination can accelerate pump wear and interfere with directional-valve operation.

• Use clean filling equipment and appropriate filtration.

• Do not mix different oils unless compatibility has been confirmed.

• Inspect the oil regularly for contamination, abnormal darkening or a burnt smell.

• Replace oil according to the manufacturer’s maintenance schedule and the actual operating conditions.

For a double-acting system, calculate oil requirements using the cylinder’s geometry and both directions of movement. Do not rely on reservoir capacity alone to determine compatibility.

Safe operation and maintenance

High-pressure hydraulic equipment must be installed and operated by trained personnel.

• Position the foot pedal to prevent accidental activation.

• Keep the pedal cable out of walkways and away from moving equipment.

• Test the pedal and directional valve before starting the production cycle.

• Inspect hydraulic hoses, couplings and connections before use. Replace damaged components immediately.

• Verify that ports A and B are connected according to the cylinder and valve documentation.

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

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

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

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

• Use appropriate lifting equipment or assistance when moving the 45 kg power unit.

• Ensure proper electrical grounding and suitable circuit protection.

Important: A 700 bar rating is a high-pressure operating limit, not a guarantee that every connected component can withstand that pressure. The complete hydraulic system must be rated for the intended working conditions.
