The input power delivered by the motor to a hydraulic pump is called brake horsepower (bHp). The horsepower needed for a hydraulic pump can be determined once basic information is known about the pumping station.

How to calculate horsepower needed for a hydraulic pump?

To find the input horsepower requirement for a hydraulic pump, use this hydraulic pump horsepower formula:

HP = (Flow x Pressure) ÷ 1714

Flow = Gallons Per Minute
Pressure = Pounds per Square Inch

Example: The input horsepower required for a pump that needs to provide 10 GPM at 1500 psi is:

HP= (10 x 1500) ÷ 1714 = 8.75 HP

Calculated out this gives an input horsepower requirement of
8.75 horsepower.

Hydraulic Horse Power is a measure of the energy per unit of time that is being expended across the bit nozzles.

Hydraulic Horse Power (HPP) formula: HHP = P x Q ÷ 1714

P stands for pressure, pounds per square in.
Q stands for flow rate in gallons per minute
1714 is a conversion factor needed to yield HHP in terms of horsepower

HHP= (P x Q) ÷ 1714 where;

HHP = hydraulic horsepower
P = circulating pressure, psi
Q = circulating rate, gpm

HHorsepower Required to Drive Pump

GPM x PSI x .0007 (a 'rule-of-thumb' calculation)

How much horsepower is needed to drive a 10 gpm pump at 2000 psi? 10 x 2000 x .0007 = 14 horsepower
