Abstract
An improved motor pump that enables the serviceability thereof, as well as improved clearance between components of the motor pump, the motor pump including a stator assembly, a rotor assembly having a front bearing for supporting a motor shaft and a bearing support member for receiving the front bearing, and a sleeve assembly including a sleeve. Both the bearing support member and the sleeve have respective pilot sections. An interface surface is defined between the bearing support member and the sleeve that includes an undulating surface with separate but multiple contact locations therebetween. The bearing support member is inserted into the sleeve so that the respective pilot sections engage to thus provide essentially a clearance-less fit therebetween.
