Online pumping calculator helps to calculate prime mover sheave diameter from user inputs. Use nearest size available depending upon belt section and number of grooves in sheave.
Formula:
d = [SPM × R × D] ÷ RPM
where,SPM = Strokes Per Minute
R = Gear Reducer Ratio
D = Gear Reducer Sheave Pitch Diameter
RPM = Revolutions per Minute-Prime Mover
