The Pump Affinity Laws are a series of relationships relating: Flow (GPM) Head (HEAD) Horsepower (BHP) RPM Speed (RPM) Impeller Dia. (DIA) Allow designers to estimate pump performance under different conditions CENTRIFUGAL PUMPS AFFINITY LAWS • GPM varies with RPM • Pump speeds up, flow increases • Pump slows down, flow decreases • GPM ...
