Abstract
A sealing system for use in sealing a rod bore and reciprocating rod including a first and second sealing assembly. The first sealing assembly, disposed within a gland in the rod bore wall, comprises a seal ring, non-sealing backup rings, and an energizer that seals only in one direction. The energizer has axial and radial grooves permitting one way sealing. The backup rings have channels preventing sealing in either direction. One embodiment of sealing system includes the first seal assembly containing no downstream backup ring.
