Strokes per Minute (SPM) Formula

Home › Science › Pump and Motor

Equation for calculate strokes per minute (spm) is,

SPM = [ RPM ÷ R ] × [ d ÷ D ]

where,
RPM = Revolutions per Minute-Prime Mover
R = Gear reducer ratio
d = Prime mover sheave pitch diameter
D = Gear reducer sheave pitch diameter
SPM = Strokes per minute
