Abstract: A drive mechanism module for use in a reciprocating pump converts rotational movement of a drive shaft to reciprocating movement of a reciprocating pump component transversely to the drive shaft. The drive mechanism module includes a connection member for attachment to the reciprocating pump component, a translating member that drives movement of the connection member in a first transverse direction while reciprocatingly translating in a second transverse direction relative to the connection member, a rotating member that rotates eccentrically with the drive shaft, and a rotary bearing assembly that permits rotation of the rotating member relative to the translating member while driving transverse movement of the translating member. The drive mechanism module may define a bearing fluid path for creating a hydrostatic or hydrodynamic fluid bearing at the interface of the connection member and the translating member.

Abstract: A fluid end assembly of a reciprocating pump has multiple fluid end bodies that are removably attached, independently of each other, to a power end assembly of the reciprocating pump, and to a manifold of the fluid end assembly. Each fluid end body defines a discharge outlet that is coaxial with a plunger bore for a reciprocating plunger, and a suction inlet that is disposed above the discharge outlet. A valve assembly is removably insertable into a valve port extending from an external surface of a manifold attached to the fluid end body, without having to remove the manifold from the fluid end body. The valve assembly includes a valve mechanism surrounded by a cylindrical valve body that lines the internal wall of the manifold defining the valve port, thereby forming a barrier between fluid flowing through the valve assembly and the internal wall.
