A mount plate for removably connecting a fluid end of a reciprocating pump to a power end for a reciprocating pump includes a first set of openings and a second set of openings, each of which extend through the main body. The first set of openings are configured to receive a first set of couplers that couple the mount plate to a front of the power end. The second set of openings are configured to receive a second set of couplers that couple the mount plate to a fluid end in a spaced relationship. The mount plate may also include a third set of openings that extend through the main body and are configured to receive pony rods of the power end.

A relationship between tie rods and a valve seat bore in a fluid end. The profile of the valve seat bores are changed to allow the tie rods to pass through the fluid end without intersecting or intercepting the internal bore geometry, while still being compatible with industry standard internal components. A relationship between a plunger bore diameter and a flow area of a valve seat in a fluid end is used to identify acceptable fluid end casing designs that can be used with industry standard couplers, such as tie rods.

A sealing assembly for a fluid end of a reciprocating pump is installable within a segment of a casing of the fluid end and is arranged to form a seal with the segment. The sealing assembly includes a closure element and a seal element. The closure element has a sealing portion with a lateral surface that faces an interior wall of the segment of the fluid end. The seal element is sized to be installed around the closure element and includes a repositionable seal. The repositionable seal is movable axially with respect to the closure element so that the repositionable seal can be positioned in multiple sealing positions.

A sealing assembly for a fluid end of a reciprocating pump is installable within a segment of a casing of the fluid end and is arranged to form a seal with the segment. The sealing assembly includes a closure element and a seal element. The closure element has a sealing portion with a lateral surface that faces an interior wall of the segment of the fluid end and that includes a single groove. The seal element is sized to be installed in the single groove and includes a repositionable seal. The repositionable seal is movable axially within the single groove so that the repositionable seal can be positioned in multiple sealing positions.

A cradle plate for high pressure reciprocating pumps is installable within a cradle disposed between a power end of a high pressure reciprocating pump and a fluid end of the high pressure reciprocating pump. The cradle plate has a main body that extends from a front surface to a back surface and a first set of openings that extend through the main body. The first set of openings are configured to receive a set of elongate couplers that position the cradle plate within the cradle in a position that secures a fluid end component against a casing of the fluid end, against a seal of the fluid end, or against both the casing and the seal.

A fluid end assembly of a hydraulic fluid pump includes a housing having a first housing bore and a second housing bore offset axially from the first housing bore. A plate is fastened to the housing. The plate has a first plate bore axially aligned with the first housing bore and a second plate bore axially aligned with the second housing bore. A first removable valve cover closes the first housing bore and a second removable valve cover closes the second housing bore. A first retainer engages the first plate bore and abuts the first removable valve cover and a second retainer engages the second plate bore and abuts the second removable valve cover.
