Abstract: A back pumping seal assembly includes a buffer seal and a backup ring. The buffer seal has inner, outer, front, and back seal faces. The buffer seal further has a contoured face portion inset and extending inwardly from the inner and back seal faces. The contoured face defines a back seal channel. The backup ring is positioned in the back seal channel of the buffer seal. The backup ring includes inner and back ring faces, and at least two channel-directed faces. The inner and back ring faces are adjacent the inner and back seal faces, respectively. A first channel-directed face extends from the inner ring face substantially parallel to the back ring face. The first channel-directed face is configured for limiting displacement of an adjacent portion of the buffer seal. A second channel-directed face extends from the back ring face at an acute angle relative thereto.

Abstract: A cartridge seal assembly includes a cylindrical housing having a shaft-receiving channel formed therethrough to define an inner annular surface. A sleeve bearing is joined to the housing at the inner annular surface. The mounting relationship of the bearing to the housing is configured to eliminate extrusion gaps, such as with a bonding attachment. As a results, the seals can be located immediately adjacent to the joint line. A pair of annular seal elements are joined to the housing and located within respective annular grooves formed in the housing at opposite sides of the bearing. A first seal located at the high pressure end of the assembly includes static and dynamic sealing areas. A portion of the static sealing area extends past the radially outermost surface of the housing to define a circumferential seal relative to the system housing. The second seal is configured as a wiper device.

Abstract: A backup ring is provided adjacent a seal apparatus for delivering a controlled space between two relatively moving parts. The backup ring provides protection against seal extrusion and failure, and can provide an auxiliary seal when needed. The backup ring includes either an arcuate surface that deforms under pressure, or a cantilever portion that deforms under pressure, or both.
