ABSTRACT:
A mechanical seal assembly for use in a coolant circulation system of a heavy diesel engine. The seal assembly includes relatively rotatable seal rings disposed in surrounding relationship to the pump drive shaft. One seal ring is non-rotatable with respect to the drive shaft and the other is non-rotatable with respect to the surrounding housing. These seal rings have opposed annular seal faces maintained in relatively rotatable contacting relationship due to the urging of a spring which acts against the non-rotating seal ring, the latter in turn being axially movably supported on a lightweight compact mounting member which stationarily seats within the stuffing box. The mounting member has a sleeve part which externally surrounds a radially projecting flange provided on the non-rotatable seal ring, which sleeve part has a large opening provided with a plurality of circumferentially elongate flats defined circumferentially therearound, preferably a hexagonal wall defining the opening, and the flange of the seal ring similarly has a mating contour, such as a hexagonal contour, so that the non-rotating seal ring is axially slidably supported within the sleeve part of the mounting member but at the same time a large and durable non-rotatable contact region is defined between the non-rotating sealing ring and the mounting member to provide a compact and durable structure possessing long life.
