Abstract
A water pump face seal assembly uses a wave spring stamped from flat stock with drive tabs which, besides providing contact force and wear take up, also serves to maintain a square, concentric contact interface and to transfer torque with almost no lost motion, isolating a joint between an elastomer seal and a seal casing from twisting stress.
