Hydraulic Pump Flow Calculator.

How do you calculate hydraulic pump flow?

To find the output flow of a hydraulic pump, use this pump flow formula:

Flow (GPM) = (RPM x Disp) / 231

RPM = Rotations Per Minute

Disp = Pump Displacement in Cubic Inches

GPM = Gallons Per Minute

Example: The output flow of a pump spinning at a rate of 2000rpm

with a displacement of 2.75
cubic inches:

Flow (GPM) = (2000 x 2.75) / 231

Calculated out this gives an output flow of 23.81GPM

(rounded to the nearest 100th)
