Hydraulic Pump Flow, Pressure and Power Calculator

This calculator enables you to calculate three parameters which are important to designing a hydraulic power pack, Flow Rate, Power and Pressure.

To use this calculator, enter your two known values and the efficiency and a zero in your unknown and lastly select your units.

If you need further conversions use our universal converter.

Pressure for gear pumps would be upto 250bar.

Power for power-packs is typically in the range of 0.25kW to 55kW.

Typically pump efficiency is between 0.85 and 0.95.
