ABSTRACT:
Disclosed is a pump that employs a magnetic coupling to connect the motor to the impeller. A simplified structure within the pump casing is employed to enable the easy removal of the pump's impeller and bushings and/or bearings. In one embodiment of the invention, the exterior surface of the impeller, including its attached magnets, is encased in a plastic bushing material. Surrounding the impeller is a tubular bushing that may at times come into contact with the bushing material of the impeller.
