1. A method of servicing a wellbore, the method comprising:
fluidly coupling a pump to a source of a wellbore servicing fluid and to the wellbore; and
communicating wellbore servicing fluid into the wellbore via the pump,
wherein the pump comprises a pump fluid end and a pump power end, wherein the pump fluid end comprises:
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; and
a suction valve stop, wherein the suction valve stop is positioned within the reciprocating element bore such that the suction valve stop contacts the suction valve assembly when the suction valve assembly is stuck open at the end of a discharge stroke of the reciprocating element, and
wherein the pump power end is operable to reciprocate the reciprocating element within the reciprocating element bore of the pump fluid end, and
wherein, when the suction valve assembly is not stuck in an open position at an end of the discharge stroke, a minimum distance between the suction valve assembly and the suction valve stop is greater than zero, such that the suction valve assembly does not contact the suction valve stop during normal operation of the pump.
