Abstract

A sealing assembly for a shaft includes a sealing component, a first ring, a second ring, and at least one energizer. The first ring is annularly disposed about the shaft, the first ring having at least one first protuberance interfittable with the sealing component. The second ring is annularly disposed about the shaft in facing opposition to the first ring, the second ring having at least one second protuberance interfittable with the sealing component. The at least one energizer energizes the seal component, the at least one energizer being adjacent the at least one first protuberance or the at least one second protuberance.
