ABSTRACT:
A lip-type fluid seal for use with a rotating shaft has a molded seal portion having a cylindrical surface comprised of two elastomeric materials. These elastomeric materials have significantly different elastic modulus values and hardness values. The cylindrical surface on both of the elastomeric materials have an axial projection which are formed during the molding process. During rotation of the shaft, the axial projections deflect to a helical configuration and cooperate with the shaft to form a viscous shear pump. The lower modulus material has a greater helical attitude and therefore increasing pumping action.
