Abstract: A valve component utilized in a fluid end assembly of a high pressure reciprocating pump includes a valve body and a sealing element. The valve body defines a recess configured to receive the sealing element. The sealing element is composed of a fiber reinforced material. The valve component is configured to be disposed in a closed position with respect to a valve seat such that a sealing surface of the sealing element engages with a corresponding sealing surface of the valve seat in the closed position.

Abstract: A retaining system for securing a closure at an installed position within a bore. The bore being in a portion of a housing and having screw threads along at least a portion thereof. The closure having an internally threaded hold extending therein. The closure in the installed position closes the bore. The retaining system comprising a retaining cover for obstructing removal of the closure from the bore. The retaining cover being receivable in the bore in a position generally adjacent the closure. The retaining cover having external threads interengageable with the screw threads of the bore such that the cover is rotatable relative to the housing in a tightening direction for movement of the cover into the bore toward the closure and rotatable in an opposite, loosening direction for movement of the cover out from the bore away from the closure. The cover having a central axis of rotation.

Abstract: A reciprocating pump assembly includes a power frame that houses a crankshaft. The crankshaft is mechanically connected to a large gear or bull gear on each end that is in mechanical engagement with a small gear or pinion bearing. A bearing housing is integrally formed as part of the power frame with an increased width and a constant inner diameter. A pinion bearing assembly, having an inner race, an outer race, and spherical bearings is placed around the shaft of the pinion bearing. The pinion is installed in the reciprocating pump assembly such that the bearing assembly rests on the bearing housing, which is integrally formed as part of the power frame. The bearing assembly is free to float in the bearing housing and provides for some lateral movement of the shaft and bearing assembly during operation of the reciprocating pump assembly.

Abstract: A tool for replacing a valve seat of a reciprocating pump has a puller shaft connected to a puller head having at least two spring-biased dogs. An operator inserts the puller head into a valve bore and through a valve seat, the dogs retracting as the puller head moves through the valve seat, then snapping back outward. A hydraulic cylinder engages the puller shaft to exert a force on the puller shaft causing the dogs to dislodge the seat. The operator then places a replacement valve seat on a shoulder in the valve bore. The operator attaches an installing head to an installing shaft and inserts the installing head into the valve bore into contact with the replacement valve seat. The hydraulic cylinder applies a force in an opposite direction on the installing shaft to push the replacement valve seat into installed engagement.
