Abstract: A valve assembly for a hydraulic frac pump includes a valve body having a spherical sealing surface, a valve seat having a circular concave sealing surface that receives and accommodates the spherical sealing surface of the valve body. The valve seat forms a fluid passageway, where the fluid passageway is completely closed when the valve body is received and accommodated in the valve seat in a closed position. The valve assembly further includes a stopper disposed above the valve body to restrict movement of the valve body when it is lifted off of the valve seat in an open position.

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: A fluid end of a reciprocating pump assembly includes a cylinder, a cover, and a valve stop. The cylinder has a fluid inlet, a fluid outlet, and an access side wall comprising an access wall inner surface that defines an access opening. The access opening provides access to an inner area of the cylinder and has an access opening axis. The cover is positioned in the access opening and forms a seal with the access wall inner surface along the access opening. The cover includes a cover axis coaxial with the access opening axis. The valve stop is positioned partially in the fluid inlet and includes a spring retainer and a column portion. The column portion includes a flange positioned between the cover and the access wall inner surface. The flange is in the shape of an arc.

Abstract: A suction cover assembly for a frac pump includes a suction cover having an annular base flange defining a sealing interface proximate to the base flange. The suction cover is dimensioned to be accommodated within a bore well of a fluid cylinder in the pump. An annular seal is seated on the sealing interface proximate to the base flange of the suction cover.
