In the case of the motor it is the rotor and the stator and for the pump it is the impeller and the volute (or diffuser). Of course the friction produced by bearings and other mechanical components (seals, stuffing box, etc) also affect pump efficiency, but the impeller and volute have the greatest influence. Lets start our investigation of centrifugal pump efficiency with the impeller.
