• 1.7 L/min high-pressure flow: helps reduce cylinder filling time compared with the specified 0.75 kW models.

• 7.9 L/min first-stage flow: supports faster initial movement when operating conditions allow.

• 10-litre oil reservoir: suitable for a range of compatible hydraulic tools, subject to their oil-volume requirements.

• Single-flow design: a straightforward solution when powered cylinder retraction is not required.

• 220V single-phase supply: suitable for compatible electrical installations.

• Service support in Ukraine: technical consultations and spare parts available through CraftOil, subject to stock availability.

Who Should Choose the DB150-D1?

The DB150-D1 is intended for applications where the hydraulic cylinder operates in one direction under pump pressure and returns through its designed mechanical mechanism or the weight of the load.

Typical users include:

• Electrical installation teams with regular cable crimping operations.

• Manufacturing workshops and assembly facilities.

• Hydraulic service centres.

• Repair and maintenance workshops.

• Industrial contractors performing repeated hydraulic operations.

• Production teams that need to reduce waiting time between working cycles.

If your tool requires hydraulic pressure in both directions, choose a compatible dual-flow power unit instead.

Single-Flow or Dual-Flow: Which Hydraulic Power Unit Do You Need?

Before choosing a hydraulic power pack, check the cylinder’s hydraulic circuit and the tool manufacturer’s specifications.

Single-acting cylinder: hydraulic pressure drives the working stroke. The cylinder returns by a spring, gravity or another designed return mechanism. A compatible single-flow unit such as the DB150-D1 may be suitable.

Double-acting cylinder: hydraulic pressure is required to drive the cylinder in both directions. This requires a compatible dual-flow power unit, such as the DB150-S2 or DB150-D2, subject to the tool’s specifications.

A cylinder with one hydraulic port is commonly single-acting, while one with two ports is commonly double-acting. However, port count alone should not replace checking the manufacturer’s documentation.

The DB150-D1 is a practical choice when your equipment does not need a powered return stroke. You get the higher specified flow rate of the 1.5 kW model without paying for a dual-flow circuit that your application does not use.

What Does the 1.5 kW Motor Mean for Working Speed?

For hydraulic equipment, the time required to extend a cylinder depends on the oil volume needed for the stroke and the actual flow delivered by the pump at the operating pressure.

The supplied specifications list a high-pressure flow rate of 1.7 L/min for the DB150-D1, compared with 0.9 L/min for the specified 0.75 kW models.

Using those nominal flow rates, the approximate filling times for different cylinder oil volumes are:

These are theoretical estimates based on the stated flow rates. Actual cycle time depends on operating pressure, cylinder characteristics, hydraulic losses, valve configuration and the return stroke.

For a team performing dozens of similar operations per shift, a shorter working stroke can improve overall productivity. The actual time saved depends on the equipment and work process.

Why Choose a Single-Flow Hydraulic Circuit?

The DB150-D1 uses a single-flow hydraulic configuration for applications that do not require powered cylinder retraction.

Potential advantages include:

• Straightforward hydraulic layout: no dual-flow circuit is needed when the connected cylinder is single-acting.

• A configuration matched to the application: avoid paying for a hydraulic function your tool does not require.

• Simplified troubleshooting: fewer circuit functions can make fault diagnosis more straightforward.

• Practical maintenance: routine service focuses on the components actually used by the system.

The best configuration is the one that matches your tool. If powered retraction is required, a dual-flow model is necessary regardless of the motor power or reservoir size.

Technical Specifications — CraftOil DB150-D1

Specifications are based on the supplied product information. Confirm the exact control configuration and operating requirements against the documentation for the specific unit before purchase.

Is the 10-Litre Reservoir Suitable for Your Hydraulic Tool?

Reservoir capacity is an important part of selecting a hydraulic power unit. The pump needs enough usable oil to complete the required cylinder stroke while maintaining a suitable oil level in the tank.

As a preliminary selection guideline, the DB150-D1’s 10-litre reservoir may suit equipment with an approximate working oil displacement of up to 8 litres. This is not a universal hydraulic design limit. The actual requirement depends on the cylinder displacement, hose volume, hydraulic circuit and usable reservoir capacity.

For equipment requiring more oil, consider a power unit with a larger reservoir, such as a 30-litre model.

Before connecting the DB150-D1 to a press or other hydraulic system, confirm:

• Whether the cylinder is single-acting.

• The oil volume required for the complete working stroke.

• The hydraulic pressure and flow requirements.

• The usable oil capacity needed for safe operation.

A reservoir that is too small for the system can lead to air entering the hydraulic circuit, unstable operation and potential equipment damage.

Electrical Supply: 220V Operation

The DB150-D1 is specified for a 220V single-phase electrical supply. The stated approximate current draw is 7 A.

Before operation, make sure the electrical circuit, socket, protective devices and grounding are suitable for the equipment.

For safe and reliable operation:

• Use a suitable power cable with an appropriate conductor cross-section.

• Avoid thin or excessively long extension leads that may cause voltage drop.

• Do not operate the unit with an extension cable tightly coiled, as this can increase heat build-up.

• Ensure proper grounding and electrical protection.

• Follow the manufacturer’s electrical installation instructions.

A generator may be suitable if its continuous output, starting capacity and voltage stability meet the motor’s requirements. Confirm generator compatibility before use rather than relying on nominal wattage alone.

Why Does the Pressure Gauge Read up to 1,000 Bar?

The DB150-D1 is specified for a maximum operating pressure of 700 bar, while the supplied 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 all connected cylinders, hoses, fittings, couplings and tools must be rated for the intended operating pressure.

Glycerine helps dampen needle vibration, making pressure readings easier to observe during operation.
