Plunger Pump and Piston Pump Flow Calculator

This Plunger Pump Flow Calculator is meant to quickly calculate the flow of a plunger pump or piston pump. By multiplying the area of the pumping chamber(s) by the RPM the pump is rotating, we can precisely calculate the flow of a reciprocating pump. Enter information into the following fields and press calculate.

Note: This Plunger Pump Flow Calculator assumes 100% volumetric efficiency, meaning it does not consider any slip or back flow of fluid through the valves of the pumps, and assumes that there is no leakage through the packing or any other part of the fluid chamber. If more in depth calculations are needed to calculate the volumetric efficiency of a plunger pump, contact the Power Zone Equipment engineering team for more information.
