  • Self aligning split mechanical seal employing a rotary seal ring having non-flat end faces
    Patent number: 10352457
    Abstract: A split mechanical seal for mounting to a housing containing a rotating shaft, including a gland assembly, a holder assembly having an inner surface and an opposed outer surface, and a rotary seal ring that is sized and configured for seating within the space defined by the holder assembly. A detent groove is formed in the inner surface of the holder assembly for at least partially seating a portion of a sealing element, and another detent groove is formed in an outer surface of the rotary seal ring for at least partially seating another portion of the sealing element. The holder detent groove and the seal ring detent groove in combination are configured to seat and to retain the sealing element.
