ABSTRACT:
An improved end face seal assembly comprises a wall mounted seat assembly having an axial sealing end face and an abutting shaft mounted sealing head assembly having an axial sealing end face slidably engaged therewith to provide a primary dynamic seal. The seat assembly has a peripheral O-ring to provide a secondary static seal at the wall mounting. The sealing head assembly comprises a cup shaped cylindrical retainer mounted on a rotating shaft by set screws. Contained within the retainer are a plurality of compression springs, a flat cylindrical disc, and a cylindrical washer. The washer having a sealing end face at one end and a counterbore at the other is captured in the retainer by a snap ring in the retainer engaging an annular shoulder on the washer. A cylindrical O-ring holder having an external O-ring and two internal O-rings provides a secondary seal between the shaft and washer. Spring force maintains contact between the rotating sealing face of the washer and the stationary sealing face of the seat to maintain the primary dynamic seal.
