A fluid end comprising a plurality of fluid end sections positioned in a side-by-side relationship. Each fluid end section is releasably attached to a connect plate. Each connect plate is attached to a power source using a plurality of stay rods. Each fluid end section comprises a housing in fluid communication with a pair of intake manifolds and a discharge conduit. A fluid routing plug is installed within each housing and is configured to route fluid throughout the housing. A plunger is installed within stuffing box attached to each housing. A number of features, including the location of seals within bore walls and carbide inserts within valve guides, aid in reducing or transferring wear.

A fluid end that provides for fluid transference in a double acting configuration for both suction and discharge operations and wherein fluid is ejected from the fluid end for high pressure environments.

A radial hydraulic wind turbine pump system incorporates: 1) a concentric, multi-lobed cam that produces multiple strokes per revolution; 2) a piston profile that maximizes the number of large-diameter pistons arranged radially around the centerline axis; 3) a flexible piston base 50 with internal oil flow; 4) hydraulically connected cylinders which counter displacement issues raised in item 2 above; 5) variable stroke capability leading to infinitely variable output and the ability to disengage unneeded cylinders from the cam; 6) integral reservoir and accumulator capacity; 7) compact, external pressure and return manifolds; 8) axially-oriented pressure and return manifolds 60, 70, and 9) a hydraulic reservoir and pressure tank integrated into the body of the pump.

A multi-piece fluid end that can be produced with fewer raw materials and at a lower cost. In one embodiment, a fluid end is formed from a first body attached to a separate second body. Their respective external surfaces may be engaged flushly, partially, or via one or more spacer elements. In some embodiments, the body pieces are flangeless to reduce stress on the fluid end. The second body may have a plurality of bores that are alignable with a plurality of corresponding bores formed in the first body. The second body may be connected to a power end using a plurality of stay rods. In other implementations, more than two body pieces may be utilized.
