A mechanical seal assembly (10, 100) comprising rotatable (20, 108) and stationary (22, 110) seal rings with faces (24, 26, 112, 114) opposing one another. Means (94, 174, 176) are provided to insure a pressure balance on the outside surface and on the inside surface of the softer seal ring, so that this seal ring does not deflect and distort, and wear in an undesirable manner. |
