A shaft seal system, operable to seal a rotatable shaft in an opening, comprises an inner wall defining the opening having a groove including a first, angled ramp portion and a second, positioning shoulder formed therein. A shaft seal assembly comprises a disc member having an outer diameter and a central opening extending therethrough. An elastomeric material, over-molded onto the disc member, comprises a diaphragm extending generally inwardly from the central opening, to define a shaft opening, a shaft seal lip extending radially inwardly from the diaphragm and an outer ring seal that extends circumferentially about the outer perimeter of the disc member. The shaft seal assembly is installed into the groove in the inner wall of the opening in the housing such that the outer ring seal forms a seal therewith.
