CA 1335112

A mechanical seal assembly disposed within a pump housing for retarding the flow and leakage of fluids and other matter from being pumped along the motor drive shaft. The mechanical seal assembly of the present invention includes a non-rotating seal ring and a seal ring which rotates with the motor driveshaft. The non-rotating seal ring (28,136,238) is resiliently mounted from the impeller side of the housing and is operably carried by the pump housing such that its seal face (42,142,242) is urged toward the seal face (40,140,240) of the rotating seal ring. A flexible assemblage (70,170,270) comprises part of the non-rotating seal mounting arrangements and assures flexibility of the non-rotating seal face despite pump operating conditions.
