Abstract: A suction cover assembly for a reciprocating pump includes a suction cover nut having a nut face and a thread configured to threadably connect the suction cover nut to a fluid cylinder of the reciprocating pump. The suction cover assembly includes a suction cover having a cover face. The suction cover is configured to be held by the fluid cylinder such that the cover face opposes the nut face of the suction cover nut. The suction cover includes first and second seals having a leakage trap defined therebetween. The leakage trap is configured to trap leakage pressure during operation of the reciprocating pump. The suction cover includes at least one leakage channel that is configured to channel the leakage pressure from the leakage trap to an interface between the cover face and the nut face.
