ABSTRACT:
A pump assembly includes a motor having a rotatable motor shaft, and a pump housing having a housing wall with an exterior side and an interior side. Within the pump housing is an impeller which is mounted on the shaft for rotation in unison therewith, and which is free to slide axially along the shaft. A first coupler is rotatably mounted on the shaft outside the housing wall and a second coupler is attached to the impeller. The first and second couplers are retentively and movably engaged and are adapted to cooperate with one another so that they will cause the impeller to move axially on the shaft to a desired position.
