The formula for calculating the required motor Hp for a high-pressure hydraulic pump is quite straightforward. This HP is generally gotten by finding the product of flow capacity in gallons per minute (GPM) and the pressure in pounds power square inch. You then need to divide the result by 1714 times the efficiency per inch (PSI) of the pump.

Overall Efficiency = Output HP / Input HP Overall Efficiency = Volumetric Eff. × Mechanical Eff. Volumetric Efficiency = Actual Flow Rate Output (GPM) / Theoretical Flow Rate Output (GPM) × 100

Use the utility below for calculating the Hydraulic (fluid power) horsepower. HP Calculator. PSI : GPM:.
