ABSTRACT:
The impeller of a fluid pump contained within an impeller housing is axially located on the drive shaft of a motor by securing the impeller to a sleeve that is slidably keyed onto the end of a motor shaft with a seal spring disposed between the sleeve and impeller housing urging the sleeve and impeller against the drive shaft so that the end thrust force is provided by the motor shaft bearings.
