Abstract
An improved system for mounting components to a rotatable shaft. The improved system may include a pump having impellers keyed to a rotatable shaft. Diffusers cooperate with the impellers to conduct pumped fluid upward from the impeller. The improved system for mounting includes a plurality of stop rings and an expansion assembly. A stop ring is secured to the shaft at each end of the rotatable component. An expansion assembly is disposed between a first stop ring and the rotatable component. The expansion assembly is axially expanded to force the rotatable component against a second stop ring.
