Claim 0:
1. A pump fluid end comprising:
a reciprocating element disposed at least partially within a reciprocating element bore of the pump fluid end;
a discharge valve assembly;
a suction valve assembly coupled with a front end of the reciprocating element such that movement of a suction valve member of the suction valve assembly away from the reciprocating element in a direction toward the discharge valve assembly opens the suction valve; and
a suction valve stop, wherein 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,
wherein, when the suction valve assembly is not stuck in an open position at the end of the discharge stroke, a minimum distance between the suction valve assembly and the suction valve stop is zero, such that the suction valve assembly contacts the suction valve stop with a closing force less than a rod load limit of a connecting rod coupled to the reciprocating element and the pump power end of the pump during normal operation of the pump.
