Abstract
Apparatus and method contemplating a high pressure fluid end assembly having a body defining a body bore and defining a recess in the body intersecting the body bore. A closure is joined to the body and forms a sealing surface. A seal is mounted to the body in the recess and configured to extend from the recess beyond the body bore to seal against the sealing surface formed by the closure.
Claims24
A method of manufacturing the fluid end assembly, comprising:
- providing a housing having a first conduit extending therethrough, and a second conduit extending therethrough that intersects the first conduit;
- forming an endless groove in the housing such that the groove surrounds the second conduit;
- positioning a seal within the groove;
- installing a tubular sleeve within the second conduit such that at least a portion of the sleeve engages with the seal;
- installing a plurality of packing seals within the sleeve;
- and
- installing a reciprocating plunger at least partially within the sleeve and the plurality of packing seals.
