ABSTRACT:
An inexpensive, efficient seal member having a tubular housing member that can be integral to or attached to a frame of a motor to form a ring seal around the shaft of the motor prior to mating the shaft with a pump or other driven device. The flexible elastomer washer member is located in a pocket at the end of the housing. The inner diameter of the flexible elastomer washer member is smaller than the shaft diameter. The thickness of the flexible elastomer washer member is larger than the depth of the pocket and is held in the pocket by a resilient retaining member having a plurality of tangs forming an interference fit with the walls of the housing. Next, the shaft is slidably extended through the flexible elastomer washer member forming the ring seal.
