Abstract
A fluid end for a high-pressure pump including a unitary body with a plurality of horizontal passages each for receiving a reciprocating plunger at one of its ends and a pressure relief valve at the other of its ends. The body is provided with a corresponding number of vertical passages each of which intersect one of the horizontal passages and contains a suction valve at its bottom and a discharge valve at its top. A suction manifold is hingedly attached to the bottom of body to provide a flow of fluid into the body via the suction valves. A discharge passage intersects the vertical passages and receives fluid pressurized by the plungers via discharge valves and ports such from the fluid end.
