Abstract: A fluid end of a reciprocating pump that includes a housing defining multiple bores extending therein. In one embodiment, the present invention involves coupling a plate to a side of a smaller fluid end forging, thereby extending the overall length of the forging to capture the outer tie rods or stay rods that a larger forged fluid end typically captures. The plate allows a smaller forged fluid end to be utilized in a tie rod spacing that is outside of the smaller fluid end envelope. In one embodiment, the plate can partially capture the side or end surface of the fluid end. In another embodiment, the plate can fully capture the side or end surface of the fluid end.
