- 59 - ABSTRACT A rotary mechanical face seal for preventing leakage of a fluid, either liquid or gas, across two relatively rotating surfaces. The seal is of the non-contacting mechanical type in which a predetermined spacing is maintained between the relatively rotatable sealing washers by formation of a pressurized fluid film between the relatively rotating surfaces. The opposed faces are constructed to provide a separation of the faces at start- up and thereby prevent damage or destruction to the faces before design pressures are achieved. This is achieved by providing at least one of the opposed faces with a deflection bearing portion which causes the necessary deflections under load. The bearing portion comprise a spaced series of lift pad sections. A variety of lift pad constructions can be used. The seal also includes a hydrodynamic radial bearing which centers the shaft in the static state to avoid shaft runout.
