DB150-S2 Double-Acting Hydraulic Power Unit – 700 Bar, 1.5 kW, 220V

Description

CraftOil hydraulic equipment · Stock in Kharkiv, Ukraine · Technical support and service in Ukraine

The CraftOil DB150-S2 double-acting hydraulic power unit is designed for professional applications where high hydraulic pressure, increased oil flow and powered cylinder movement in both directions are required.

Combining a 1.5 kW electric motor, a two-stage hydraulic pump and a 10-litre oil tank, the DB150-S2 is a powerful solution for workshops, production facilities, maintenance operations and installation teams that use hydraulic equipment regularly.

The unit delivers a maximum operating pressure of 70 MPa (700 bar) and is specified for a flow rate of 7.9 L/min at the first stage and 1.7 L/min at the second stage. Its double-acting hydraulic circuit has two working lines, A and B, allowing compatible cylinders to extend and retract under hydraulic pressure.

Powered by a 220V single-phase supply, the DB150-S2 is suitable for installations where a compatible high-pressure hydraulic power source is required without a three-phase electrical connection.

Key Advantages of the DB150-S2

• 700 bar maximum operating pressure for compatible high-pressure hydraulic equipment.

• 1.5 kW electric motor for demanding applications.

• Two-stage hydraulic pump with a specified flow rate of 7.9 L/min at the first stage and 1.7 L/min at the second stage.

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

• 10-litre oil tank for the hydraulic system.

• Remote control for convenient operation from the work area.

• Glycerine-filled pressure gauge with a scale up to 1,000 bar.

• 2-metre high-pressure hose included.

• Technical advice and local service support from CraftOil in Ukraine.

The DB150-S2 is particularly worth considering for professional operations where both controlled movement and a higher specified flow rate are important.

How Does the Double-Acting Hydraulic Circuit Work?

The DB150-S2 has two hydraulic working lines, A and B. Oil is directed alternately to the piston-side and rod-side chambers of a compatible double-acting hydraulic cylinder.

This allows the piston rod to extend and retract under hydraulic pressure instead of relying solely on a return spring or gravity.

When Is a Double-Acting Hydraulic Power Unit Needed?

Choose a double-acting configuration when:

• Your cylinder requires hydraulic pressure in both chambers.

• The piston rod must retract under load.

• You need controlled movement in both directions.

• Your equipment performs repeated operating cycles.

• You use compatible pipe benders, hydraulic pullers, presses or other equipment requiring powered retraction.

A double-acting cylinder commonly has two hydraulic ports, but always verify the cylinder’s documentation and connection diagram before selecting a power unit.

If your cylinder is single-acting and returns by spring or gravity, a single-acting power unit may be sufficient. CraftOil can help you determine whether the DB150-S2 is the right solution for your application.

What Does the 1.5 kW Motor Offer?

The DB150-S2 combines a 1.5 kW motor with a two-stage pump. According to the supplied specifications, its flow rates are:

• First stage: 7.9 L/min at 2 MPa.

• Second stage: 1.7 L/min at 70 MPa.

Compared with the listed 0.75 kW models, which deliver 5 L/min at the first stage and 0.9 L/min at the second stage, the DB150-S2 provides a higher specified flow rate.

The actual operating cycle time depends on the cylinder’s effective volume, required pressure, load, hose and connection configuration, and the hydraulic circuit. Higher flow can reduce the time required to move a given volume of oil, but the actual performance must be assessed for the complete system.

Example of Theoretical Cylinder Filling Time

For illustration, filling a 0.5-litre cylinder chamber at a constant flow rate would take approximately:

• 33 seconds at 0.9 L/min

• 18 seconds at 1.7 L/min

These are theoretical calculations based on flow rate and volume. Actual cycle times may differ, particularly when the pump operates under changing pressure and load. They do not represent guaranteed machine cycle times.

A Practical Consideration: Weight

The DB150-S2 weighs 45 kg, compared with 25 kg for the listed HHB-700AB model.

For a stationary workshop or production station, this may be an acceptable trade-off for the higher motor power and specified flow rate. If you need to move the power unit frequently between job sites, the lighter HHB-700AB may be more convenient, provided its flow rate meets your requirements.

Technical Specifications

Important pressure rating information: The maximum specified operating pressure of the DB150-S2 is 700 bar. The 1,000 bar gauge scale does not increase the permissible operating pressure of the power unit. The cylinder, hoses, fittings, couplings and connected equipment must all be rated for the intended operating conditions.

Remote Control and Pressure Gauge

Remote Control

The remote control allows the operator to start and stop the power unit without having to stand beside its housing. This can make operation more convenient when the unit is installed away from the working area.

The remote control does not replace safe working practices. Operators must keep clear of moving components and pressurized hydraulic connections.

Glycerine-Filled Pressure Gauge

The DB150-S2 includes a glycerine-filled pressure gauge with a scale extending to 1,000 bar.

Glycerine helps dampen needle vibration, making pressure readings easier to observe in operating environments where vibration may occur. The 1,000 bar scale is the gauge’s measurement range, not the power unit’s pressure rating.

Electrical Connection: 220V

The DB150-S2 is specified for a 220V single-phase electrical supply.

For reliable and safe operation:

• Use a suitable, properly grounded electrical connection.

• Ensure that the wiring and protective devices meet the motor’s requirements.

• Avoid undersized extension cables.

• Do not leave an extension cable tightly coiled while operating equipment.

• Follow the manufacturer’s electrical installation instructions.

The actual current draw can vary with operating conditions. Check the motor nameplate and product documentation when planning the electrical connection.
