ABSTRACT:
This disclosure relates to a seal which is particularly suited for use in a coolant pump of an internal combustion engine. The seal parts are subjected to high rotational torques during operation of the pump, and the seal parts are constructed and assembled in such a manner as to accommodate the rotational torques. The seal includes a flexible bellows having a composition which withstands the engine coolant on one side and oxidation on the other side, and has ribs which strengthen it. The seal faces are constructed of a material and have dimensions to reduce the magnitude of the rotational torques. The seal parts are secured together so as to prevent them from being pulled apart by the rotational torques, adhesives being used for this purpose which withstand the engine coolant.
