摘要： 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.

摘要： A closure element for a fluid end of a reciprocating pump is installable within a segment of a casing of the fluid end to substantially close the segment. The closure element includes a main body that extends from an interior surface to an exterior surface, and at least a portion of the main body has a non-circular cross-sectional shape. A fluid end of the closure element may include a plurality of segments and at least a portion of at least one segment of the plurality of segments may have a non-circular cross-sectional shape configured to receive and secure a closure element with a non-circular cross-sectional shape.

摘要： 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.

摘要： A retaining assembly for coupling a fluid end component to a fluid end casing. The retaining assembly includes a pair for clamp members, each of which has a pair of rails that define a wedge-shaped groove therebetween. The groove applying an increasing amount of pre-load force or tension to a flange of the fluid end components and a flange of the fluid end casing to drive them together. The amount of pre-load tension applied can vary and can be determined by the user and amount of tightening of the clamp members.

摘要： A valve component utilized in a fluid end assembly of a reciprocating pump may contain a multi-piece construction. The valve component may include a valve body portion, a leg assembly portion, a sealing element, and an insert at least partially captured between the valve body portion and the leg assembly portion. The insert may be constructed from a carbide or a ceramic material, and, when the valve component is fully assembled, may be compressed between the valve body portion and the leg assembly portion. The insert may at least partially form the strike surface of the valve component. The valve body portion and the leg assembly portion may both be constructed from a metallic material, and the valve body portion may define a sealing seat. The sealing element may be constructed from an elastomeric material that may be pre-formed and then compression molded onto the seat of the valve body.

摘要： 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.

摘要： 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.

摘要： A tension assembly that is used with a fluid end of a reciprocating pump. The internal components of the fluid end are subject to high pressure, which negatively impacts the lifetime of any internal component. The tension assembly can be used to apply a preload to an internal component. The tension assembly includes a pair of sleeves or rings, one sleeve being coupled to the fluid end housing and the other sleeve is movable relative to the coupled sleeve. The movable sleeve engages the internal component and as that sleeve is moved inwardly toward the internal component, a force or preload is applied to the internal component, which helps set and retain it in place.
