Abstract
An improved pump assembly having a housing assembly, a motor assembly and a pump, the housing assembly having a motor mounting plate supporting the motor assembly and the pump. The motor assembly has a motor with a rotatable shaft extending through a shaft aperture in the motor mounting plate to operatively connect to an impeller of the pump. The motor assembly includes a shaft sealing and alignment assembly which provides precise alignment and sealing of the rotatable shaft by a shaft seal mount and a shaft seal disposed in a precisely configured shaft seal bore therein. The shaft seal mount attaches to the motor and has its distal end disposed in the shaft aperture of the motor mounting plate.
