## 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
