ABSTRACT:
A motor mounted pump assembly for use with an agitator-type clothes washing machine is disclosed which includes a pump, having an impeller located in a pump housing, mounted to a motor casing such that a drive shaft from the motor extends into the pump housing and drivingly engages the impeller. Interposed between the pump and motor is a cover member which is fixedly secured to the pump housing and which is intended to divert any leakage from the pump housing from coming into contact with the motor or any associated electrical components of the washing machine. By fixedly securing the cover member to the pump housing, the pump and cover member may be removed from the motor as a unitary piece in the event the pump needs to be replaced or repaired. Furthermore, at the connection points between the cover member and the pump housing, the cover member is formed with embossed areas which function to divert any fluid leaking from the pump housing away from these areas. Additional openings are provided in the cover member to permit mounting legs, formed integral with the pump housing, to be directly secured to the motor casing. These openings are surrounded by upstanding ridges which also function to divert any fluid leakage away from these openings.
