Abstract
In one aspect, fluid ends are described herein having structure and design addressing degradation mechanisms in pumping operations employing fluids comprising abrasive particles. Briefly, a fluid end for a reciprocating pump comprises a body portion comprising a bore having an inner diameter surface, and a reciprocating plunger at least partially disposed in the bore. A sleeve is positioned within the bore between the inner diameter surface and plunger, the sleeve engaging the inner diameter surface via an interference fit.
