Abstract

A pump fluid end having a reciprocating element a discharge valve assembly, a suction valve assembly, and a suction valve stop. The reciprocating element is disposed at least partially within a reciprocating element bore of the pump fluid end. The suction valve assembly is coupled with a front end of the reciprocating element. The suction valve stop is positioned within the reciprocating element bore such that the suction valve stop contacts and applies a closing force to the suction valve assembly when the suction valve assembly is stuck open at the end of a discharge stroke of the reciprocating element.
