Description

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

The CraftOil DB-150S1 electric hydraulic power unit is a high-flow hydraulic power pack designed for applications where operating speed and productivity matter as much as maximum pressure.

With a 1.5 kW electric motor, a 10-litre hydraulic oil reservoir and a maximum working pressure of 70 MPa (700 bar), the DB-150S1 is designed to power compatible hydraulic presses, cylinders, jacks and professional hydraulic tools.

Unlike lower-powered 0.75 kW models, the DB-150S1 provides higher rated flow at both pump stages. It delivers up to 7.9 L/min during the initial low-pressure stage and 1.7 L/min during the high-pressure stage. This helps reduce cylinder movement time and waiting between operations when the connected hydraulic system is correctly matched to the power unit.

The unit operates from a 220V single-phase AC supply and features a two-stage hydraulic pump, manual two-position directional control valve, glycerine-filled pressure gauge and 2-metre high-pressure hose.

The DB-150S1 is particularly suitable for workshops, production facilities, electrical installation teams and operators who perform repetitive hydraulic operations throughout the working day.

If you need a 700 bar electric hydraulic pump for a hydraulic press or industrial tool and want higher flow than a typical 0.75 kW unit, the DB-150S1 is worth considering.

The Main Advantage: Higher Hydraulic Flow and Faster Operation

The DB-150S1 is designed for users who need to perform multiple hydraulic operations during a shift.

Its higher flow rates can reduce the time required to extend a compatible cylinder, especially during high-pressure operation. The actual improvement depends on cylinder displacement, working pressure, load and the hydraulic circuit.

DB-150S1 vs DYB-63A / DYB-63H

What does the higher flow rate mean in practice?

Cylinder movement time can be estimated by dividing the required oil volume by the pump flow rate.

For example, supplying 0.5 litres of oil at a constant flow of 0.9 L/min takes approximately 33 seconds. At 1.7 L/min, the same volume takes approximately 18 seconds.

These figures are theoretical estimates. Actual movement time depends on operating conditions, pressure, pump performance and hydraulic system losses.

For repetitive production work, a shorter cylinder movement time can reduce waiting between cycles and improve workflow efficiency.

The trade-off is weight: the DB-150S1 weighs 45 kg, compared with 25 kg for the lower-powered models.

• Choose the DB-150S1 if higher flow and repeated operation are priorities and the unit can remain in a fixed workshop or production area.

• Consider the 0.75 kW models if lower weight and easier transport between job sites are more important than maximum flow.

What Does “Single-Circuit Hydraulic Power Unit” Mean?

The DB-150S1 is designed around a single hydraulic working outlet for operating one compatible tool at a time.

It is intended for hydraulic systems where the connected cylinder or tool is designed to return when pressure is released, typically through a spring-return or gravity-return mechanism.

Key benefits of a single-circuit configuration

Straightforward operation

A single working circuit can simplify hydraulic connections and operation when the application does not require multiple controlled outlets.

Suitable for compatible single-acting cylinders

The unit can power cylinders and tools designed for pressure-driven movement with a manufacturer-approved return mechanism.

Practical for repetitive hydraulic work

The electric motor reduces the need for manual pumping, while the higher flow rates can help shorten operating cycles when compared with lower-flow units.

Important compatibility limitations

The DB-150S1 should not be assumed suitable for double-acting hydraulic cylinders that require controlled oil supply to both sides of the piston.

It is also not intended to operate two independent hydraulic tools simultaneously.

If your application requires a double-acting cylinder, multiple hydraulic outlets or a different valve arrangement, contact CraftOil before purchasing. We can help assess the required configuration.

Technical Specifications

The stated flow rates apply to their respective pump stages. Actual cylinder speed depends on cylinder displacement, load, operating pressure and hydraulic circuit design.

Why Is the Pressure Gauge Rated up to 1000 Bar?

The DB-150S1 comes with a glycerine-filled pressure gauge with a scale extending to 1000 bar, while the maximum rated pressure of the hydraulic power unit is 700 bar.

A gauge with a higher full-scale rating provides measurement headroom and allows the normal operating pressure to be read below the upper end of the scale.

Glycerine inside the gauge helps dampen needle vibration caused by mechanical movement and pressure pulsations, supporting more stable readings.

Important: The 1000 bar gauge scale does not increase the maximum working pressure of the power unit. The DB-150S1 remains rated for a maximum pressure of 700 bar. All connected cylinders, hoses, couplings, valves and tools must be rated for the intended operating pressure.

Operating from a 220V Power Supply

The DB-150S1 is designed for a 220V single-phase AC supply, making it suitable for many workshop and production environments with a compatible electrical installation.

At 1.5 kW, the motor’s nominal power divided by 220V gives approximately 6.8 A. Actual supply current can be higher depending on motor efficiency, power factor, starting current and operating conditions.

For safe and reliable operation:

• Use a correctly grounded electrical outlet and a suitable circuit.

• Follow the manufacturer’s requirements for cable size, protection and connection.

• Avoid thin household extension leads and unsuitable cable reels.

• Do not leave an extension cable tightly wound on a reel while operating the equipment.

• Check the motor nameplate and electrical documentation before installation.

Customers in countries using different mains voltages or frequencies should confirm electrical compatibility before ordering.

Who Benefits Most from the DB-150S1?

This model is particularly relevant for:

• Electrical installation teams performing frequent cable crimping operations

• Industrial maintenance and repair facilities

• Automotive and mechanical workshops

• Small and medium-sized manufacturing operations

• Production areas with repeated hydraulic pressing cycles

• Operators of compatible hydraulic cold-press oil extraction machines

If your workflow involves many repeated operations during a shift, the higher flow rate may be more valuable than the lower weight of a compact power unit.

Compatibility with CraftOil Hydraulic Presses

CraftOil manufactures hydraulic presses rated at 30, 50 and 70 tonnes for cold-pressed oil production.

Our practical experience with hydraulic press systems helps us assess the relationship between operating pressure, cylinder displacement, flow rate and pressing performance.

The DB-150S1 may be suitable for converting a compatible manually operated hydraulic press to electric-powered hydraulic operation. Instead of repeatedly pumping a manual jack, the operator controls the hydraulic flow through the unit’s directional control valve.

Why consider the DB-150S1 for repetitive oil pressing?

• Reduced manual effort: electric hydraulic operation eliminates repeated manual pumping.

• Higher rated flow: the 1.7 L/min high-pressure stage can shorten cylinder movement time compared with a 0.9 L/min unit under comparable conditions.

• Larger reservoir: the 10-litre tank provides greater nominal oil capacity than the 7-litre tanks on the DYB-63A and DYB-63H.

• Practical for stationary production: the 45 kg unit is better suited to a fixed working position than to frequent manual transport.

The best power unit depends on the hydraulic cylinder’s displacement, required pressing force, cycle time and the press manufacturer’s connection requirements.

Contact CraftOil with your press model and technical specifications. We will help assess whether the DB-150S1 is appropriate or whether a smaller, lighter or differently configured power unit would better meet your needs.

Which Hydraulic Oil Should You Use?

Correct hydraulic oil selection supports reliable pump operation, lubrication and the service life of seals and other hydraulic components.

1. Hydraulic oil viscosity

Depending on the manufacturer’s requirements and operating temperature, suitable options may include industrial hydraulic oils in the ISO VG 32 or ISO VG 46 viscosity grades, such as compatible HLP 32 or HLP 46 products.

Other hydraulic oils should only be used if their specifications meet the requirements stated in the equipment documentation.

Always check the DB-150S1 operating manual or nameplate before filling the reservoir.

2. Oil quantity and reservoir capacity

The nominal reservoir capacity is 10 litres. This does not necessarily mean the reservoir should be filled to its maximum capacity in every installation.

Maintain the oil level within the manufacturer’s specified limits and ensure that the system has enough usable oil for the complete operating stroke of the connected cylinder.

A larger reservoir can provide additional oil capacity for suitable applications, but the correct quantity depends on the hydraulic circuit and the connected equipment.

3. Oil cleanliness

Use clean hydraulic oil and suitable filtration during filling. Contamination can damage the pump, valves and seals and may lead to unstable operation or premature component failure.

4. Oil replacement

Inspect the oil regularly and follow the manufacturer’s maintenance schedule. Oil that becomes unusually dark, develops a burnt smell or shows signs of contamination should be investigated and replaced when required.

5. Do not mix incompatible oils

Do not mix hydraulic oils of different types or manufacturers unless compatibility has been confirmed.

Safety and Operating Recommendations

Hydraulic equipment operating at 700 bar requires appropriate installation, inspection and safe working procedures.

• Inspect the high-pressure hose before every start-up. Replace hoses showing cracks, swelling, leaks or other damage.

• Never exceed the rated working pressure of the power unit or any connected cylinder, hose, coupling, valve or tool.

• Never disconnect quick couplings while the system is pressurised.

• Release pressure safely before maintenance or disconnecting hydraulic lines, following the manufacturer’s instructions.

• Wear suitable eye protection and keep hands away from hydraulic leaks. High-pressure oil can penetrate the skin and requires immediate emergency medical attention.

• Monitor oil temperature during prolonged operation and follow the manufacturer’s duty-cycle requirements.

• Use a properly grounded electrical outlet and a suitable electrical installation.

• Confirm that all connected hydraulic components are rated for the intended operating pressure.

• The unit weighs 45 kg. Use appropriate lifting equipment or a two-person lift when necessary, and secure the unit properly during transport.

Installation and connection should be performed by a qualified person familiar with high-pressure hydraulic systems.
