CA 2506946

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.

L'invention concerne un système de pompage qui comprend un composant joint énergisant possédant une ouverture qui s'étend à travers celui-ci, et un composant enveloppe de joint présentant une base et une membrane évasée de forme toroïdale qui s'étend depuis la base. Le corps et la membrane évasée sont formés de manière monolithique par un matériau de joint polymère inerte. La membrane évasée s'étend à travers l'ouverture et entoure le composant joint énergisant afin d'isoler ce dernier d'un fluide du système de pompage. Ladite membrane évasée peut s'étendre axialement depuis le corps et entourer ledit composant joint énergisant. Ladite membrane évasée peut entourer ledit composant joint énergisant et chevauche une partie de la base. Ledit composant enveloppe de joint peut être monté autour du composant joint énergisant. Ledit composant enveloppe de joint peut comprendre une bride s'étendant radialement vers l'extérieur depuis la base.
