  • Patent number: 9605672
    Abstract: A reciprocating-rod seal (10) comprising a one-piece rigid support (20) and a one-piece elastomeric body (30) bonded to the rigid support (20). A notch (40) separates an ID fluidside portion (41) of the elastomeric body (30) from an OD fluidside portion (42) of the elastomeric body (30), and the ID fluidside portion (41) forms a sealing lip (43). A groove (50) separates an ID airside portion (51) of the elastomeric body (30) from an OD airside portion (52) of the elastomeric body (30), and the ID airside portion (51) forms a wiping lip (53). The sealing lip (43) prevents fluid escape during forward and return strokes of a reciprocating rod, and the wiping lip (53) removes dirt, dust, or other debris from the rod during return strokes. The seal (10) can serve as the primary seal for a mudpump pony rod and/or a mudpump plunger rod.

  • Patent number: 6290235
    Abstract: Fluid sealing system for installation within an assembly including a stationary machine part having a generally annular surface, and a reciprocable machine part having a generally cylindrical surface disposed concentrically with the annular surface of the stationary machine part. The system includes annular primary and secondary seal members each configured to be received within a corresponding gland of the annular surface coaxially intermediate the cylindrical surface of the movable machine part and a peripheral wall of the glands. The primary seal member has axially spaced-apart upper and lower end faces, and radially spaced-apart inner and outer diameter faces. The inner diameter face is formed to contact the cylindrical surface of the movable machine part along at least one dynamic sealing surface, and the outer diameter face is formed to contact the peripheral side wall of the gland along at least one static sealing surface.

  • Patent number: 5472216
    Abstract: A seal assembly for a valve stem has a primary seal ring with a relatively rigid gland member having an annular base of generally rectangular cross-section and a pair of flexible sealing lips formed in one piece with the base and extending outwardly from one side thereof. The sealing lips define a cavity for an elastomeric expander ring. The expander ring is disposed within the cavity and retained therein by the sealing lips. Each sealing lip has a sealing edge on the outer surface thereof which is pre-loaded against the valve stem and the valve housing when the primary seal ring is installed around the valve stem. Each sealing lip has a flared angle which narrows down to a thickness of between 0.033 and 0.041 inches along the length of the sealing lip between the base and the sealing edge.

  • Patent number: 4328972
    Abstract: A sealing ring having a U-shaped shell member and an actuator member formed in situ from liquid elastomer. The shell member has a base portion with two legs extending from the base to form a cavity therebetween which is filled with the liquid elastomer and cured in situ. This integrally formed U-shaped composite ring seal yields a highly reliable seal with minimal dimensional variation problems and is easy and economical to manufacture.
