A fluid end assembly of a hydraulic fluid pump includes a housing, a plug member, a lock cover, and at least one retention pin. The housing may include at least one bore. The plug member may be positioned at least partially within the at least one bore. The lock cover may be coupled to the housing and configured to retain the plug member within the at least one bore during operation of the fluid end assembly. The at least one retention pin may extend at least partially through a portion of the lock cover to retain the lock cover in a rotational position that retains the plug member at least partially within the bore.

Fluid end of a hydraulic fluid pump and method of assembling the same

A method of assembling a fluid end includes inserting a valve through a bore of a housing of the fluid end and into an interior volume of the fluid end, inserting a valve cover into the bore such that the valve cover seals the bore, and coupling a lock cover to the housing, the lock cover positioned over the bore to prevent removal of the valve cover from the bore. When the lock cover is coupled to the housing, the lock cover does not apply a preload against the valve cover.

A wear plate assembly of a drill pump includes a wear plate extending between a first axial end and a second axial end. The wear plate includes an annular cross-section defined by a bore surface and a radial seal surface, an annular seal groove in the radial seal surface at a position between the first axial end and the second axial end, and a shoulder extending radially outward from the radial seal surface at the second axial end.

Wear plate for a drill pump

A piston rod assembly of a hydraulic fluid pump includes an extension rod extending axially between a first axial end and a second axial end. The extension rod is defined by a first portion, a second portion, and a third portion. The first portion extends from the first axial end to the third portion and the second portion extends from the second axial end to the third portion. The piston rod assembly further includes a sleeve extending around the third portion. The sleeve is configured to couple the first portion to the second portion.
