Single acting pump displacement

  1. This calculator can be used to determine a power pump's displacement (Qdisp) knowing the number of plungers (M), the plunger diameters (D), the rotating speed (N) and the stroke length (SL). If you enter any four of these variables as inputs, the calculator will determine the fifth variable.
  1. This estimates your single acting plunger pump flow if you assume a 100% volumetric efficiency.
  2. Multiply your result by your actual volumetric efficiency to get your actual flow rate.

Input 5 of 6 variables to solve for the unknown.
