How to Select the Right Hydraulic Power Unit

1. Understanding Flow Rate, Pressure, and Motor Power

• Flow Rate (L/min) – Determines cylinder / actuator speed and or a hydraulic motor's RPM.
• Pressure (Bar/PSI) – Defines the force and or torque generated.
• Power (kW/HP) – The electric motor must meet flow and pressure demands.

Formula: kW = (Flow x Pressure) ÷ (600 x Pump Efficiency)

Example: A flow rate of 10 L/min at 150 bar requires approximately 3.0 kW (assuming 85% pump efficiency).

2. Choosing the Right Pump Type

• Gear Pumps – Compact, cost-effective, reliable, and ideal for moderate pressure applications (30-200 bar).
  All our units use gear pumps.
• Vane Pumps – More efficient and quieter; ideal for smooth, consistent flow.
• Piston Pumps – High efficiency, suitable for high-pressure applications (150-420 bar).

3. Selecting the Correct Pump Displacement

Formula: Displacement (cc/rev) = (Flow Rate in L/min × 1,000) ÷ (Motor RPM)

Example:

• 1,400 RPM motor with 20 Lt/min flow = (20 Lt/min x 1,000) / RPM 1,400 = Pump displacement = 14.3 cc/rev.
• 2,800 RPM motor with 20 Lt/min flow → (20 Lt/min x 1,000) / RPM 2,800 Pump displacement = 7.1 cc/rev.

4. Choosing the Right Tank Size

• Oil storage: The tank should be 2-3 times the flow rate for optimal operation.
• Heat dissipation: Larger tanks help prevent overheating.
• Custom options: Choose from various tank sizes and materials.

Additional System Components

• Return filters & filler breathers – Maintain clean oil for extended system life.
• Suction strainers – Protect the pump from contaminants.
• Oil level & temperature indicators – Prevent overheating or low oil conditions.
• Pressure gauges – Monitor system pressure for easy troubleshooting.
