    Abstract: A suction cover assembly for a reciprocating pump assembly includes a suction cover having a body that is configured to be held at least partially within an access port of a fluid cylinder of the reciprocating pump assembly. The body includes a receptacle that includes at least one radial opening that extends through the body. The suction cover assembly includes a suction cover retainer that includes a plug configured to be at least partially received within the receptacle of the body. The suction cover retainer includes at least one retention segment configured to be held within the at least one radial opening of the body. The plug is configured to be moved between a locked position wherein the at least one retention segment is in a radially extended position and an unlocked position wherein the at least one retention segment is in a radially retracted position.

    Abstract: The valve member includes a valve body and a seal. The valve body defines a first frusto-conical surface and an outside annular cavity. The seal extends within the outside annular cavity and includes a first tapered and circumferentially-extending surface adapted to sealingly engage the tapered surface of the valve seat. In another aspect, the seal includes an annular bulbous protrusion from which the first tapered and circumferentially-extending surface angularly extends, the first tapered and circumferentially-extending surface extending between the annular bulbous protrusion and the first frusto-conical surface of the valve body. In another aspect, an offset distance is defined between the first frusto-conical surface of the valve body and at least a portion of the first tapered and circumferentially-extending surface of the seal, the offset distance extending in a direction that is perpendicular to at least the first frusto-conical surface of the valve body.

    Abstract: A valve assembly adapted for use in oil and gas operations. In one aspect, the valve assembly includes a valve body defining an internal region, an inlet passageway, and an outlet passageway, the inlet and outlet passageways extending into the internal region; a valve seat connected to the valve body and defining a fluid passageway; a clapper extending within the internal region and defining an annular groove; and a seal extending within the annular groove of the clapper and adapted to sealingly engage the valve seat. In an example embodiment, the clapper is actuable between an open configuration, in which fluid flow is permitted through the fluid passageway; and a closed configuration, in which the seal sealingly engages the valve seat to at least partially restrict fluid flow through the fluid passageway.

    Abstract: A plug valve including a valve body defining an internal cavity, a first passage, and a second passage, a plug defining a third passage and being rotatable within the internal cavity, and an insert extending within the internal cavity between the valve body and the plug. The insert defines an interior surface and an opening aligned with the first passage of the valve body. The insert may also define a sealing surface extending around the opening and standing in relief against the interior surface to sealingly engage the plug. In addition to, or instead of, the sealing surface, the insert may define a projection at least partially defining the interior surface. In addition, a boot may be connected to the valve body and interlocked with the projection to prevent, or at least reduce, rotation of the insert relative to the valve body when the plug rotates within the internal cavity.

    Abstract: A method and apparatus for a reciprocating pump assembly, including a crosshead and a connecting rod. The crosshead includes a main body having a cylindrical bore formed therethrough and defining a bearing surface, and a window formed through the main body and into the cylindrical bore. The connecting rod includes a small end disposed within the cylindrical bore and a beam portion extending through the window and being connected to the small end. In an exemplary embodiment, a bearing including a tubular body and a cutout is disposed within the cylindrical bore. In another exemplary embodiment, a clamp engages both the main body of the crosshead and the respective opposing end portions of the small end, thus reducing axial displacement of the small end relative to the crosshead.

    Abstract: A valve assembly for use in a fracturing pump including a valve member movable into and out of engagement with a valve seat body. The valve seat body includes an outer surface and an inner surface, the inner surface forming a fluid bore extending between a first end and a second end of the valve seat body. The body further includes a seating surface extending radially from the inner surface and facing the valve member, the seating surface having a recessed area. An insert is disposed in the recessed area forming at least a portion of the inner surface and at least portion of the seating surface. The valve seat body first end has a diameter different from a diameter valve seat body second. The difference between diameters allows the valve seat body outer surface to be supported by the fluid passageway.

    Abstract: A fluid end block for attachment to a power end of a high pressure reciprocating pump includes a main body portion having an outwardly facing body forward face, an outwardly facing body rear face opposite the body forward face, and opposing side surfaces. A web portion protrudes outwardly from the outwardly facing body forward face. The web portion may have an outwardly facing web forward face and a curvilinear side surface. The web portion may be integral with the main body portion. A plurality of bosses protrude from the web forward face and having a forward facing end. The plurality of bosses may be integral with the main body portion and the web portion. A plunger bore extends through one of the plurality of bosses configured to receive a reciprocating plunger.
