Calculating Required Power rpm gpm x psi = electric motor hp ,460 When using a variable frequency controller (VFD) calculate the hp or kw at minimum and maximum pump speed to ensure the correct hp or kw motor is selected. Note that motor manufacturers typically de-rate the service factor to 1.0 when operating with a VFD. NPSHr (feet of water) rpm l/min x bar = electric motor kw Calculating Pulley Size motor pulley OD pump rpm Net Positive Suction Head (NPSHr) Positive inlet pressure required for: Revolutions Per Minute A) All pumps with PFE diaphragms = Self-priming: pump pulley OD motor rpm B) Pumps with B-cam or G-cam (consult factory) X E, S Each Hydra-Cell pump has different lift capability depending on model size, cam angle, speed, and luid characteristics. o ensure that your speciic lift characteristics are met, refer to the inlet calculations regarding friction, and acceleration head losses in your Hydra-Cell Installation & Service Manual.
