Abstract
A high-pressure pumping system including an energizing seal component having an aperture extending therethrough and a seal jacket component having a base and a toroidally-shaped flared membrane extending from the base. The body and the flared membrane are monolithically formed of an inert polymeric seal material. The flared membrane extends through the aperture and encircles the energizing seal component to isolate the energizing seal component from fluid of the pumping system. The flared membrane may extend axially from the body and encircle the energizing seal component. The flared membrane may encircle the energizing seal component and overlaps a portion of the base. The seal jacket component may be formed around the energizing seal component. The seal jacket component may include a flange extending radially outwardly from the base.
