US 2026/0168490 A1 · HIGH PERFORMANCE SEALING ASSEMBLY

Abstract

A high performance sealing assembly may be positioned along a plunger bore for pumps such as high-pressure reciprocating pumps having a housing with one or more plunger bores defined therein and through which a plunger reciprocates. The sealing assembly may include a series of sealing elements. One or more of the sealing elements may include a base material combined with a thermally conductive material, a low coefficient of friction material, or a combination of both, so as to facilitate dissipation of heat generated by the reciprocation of the plunger through the sealing assembly, and/or facilitate a reduction in heat generated by such reciprocating movement of the plunger.
