Abstract: A linear frac pump includes a fluid end having an inlet valve disposed proximate to an inlet port, and a discharge valve disposed proximate to a discharge port. The pump further includes a first plunger rod housed within a first plunger housing, the first plunger rod having first and second ends, the first end being in fluid communication with the fluid end, and the second end being coupled to a first actuator. The pump includes a second plunger rod housed within a plunger housing, the second plunger rod having first and second ends, the first end being in fluid communication with the fluid end, and the second end being coupled to a second actuator. The first and second plunger rods and housings are coupled to the fluid end and the first and second plunger rods operate in sync to drive fluids inward from the inlet port and outward via the discharge port being regulated by the inlet and discharge valves.

Abstract: A suction cover nut for a reciprocating pump includes a body configured to be at least partially received within an access port of a fluid cylinder of the reciprocating pump. The body extends a length along a central longitudinal axis. The body includes a thread configured to threadably connect the suction cover nut to the fluid cylinder within the access port. The thread extends along the central longitudinal axis of the body. The body includes a recess configured to receive a suction cover of the reciprocating pump therein. The recess is tapered inwardly along the central longitudinal axis of the body.

Abstract: A plate segment for a reciprocating pump power end frame assembly, the power end frame assembly having a pair of end plate segments and at least one middle plate segment disposed between the end plate segments. The plate segment consists of the middle plate segment or one of the pair of end plate segments and includes a plate having a front wall, a rear wall, a top wall, a bottom wall and a pair of sidewalls and at least one opening forming a bearing support surface, the opening extending through the plate. The plate segment further includes at least one extension extending from at least one of the sidewalls of the plate at a position to align with and contact a corresponding extension on an adjacently positioned plate.

Abstract: A power end frame assembly for a reciprocating pump that includes a first and second end plate segment each including annular bearing support surfaces configured to support a crankshaft bearing assembly. At least one middle plate segment is disposed between the first and second end plate segments and includes an annular bearing support surface configured to support a crankshaft bearing assembly. The annular bearing support surfaces of the first and second end plate segments and the at least one middle plate segment each have a diameter and are coaxially aligned. The diameter of at least one of the first and second end plate segments is different from the diameter of the at least one middle plate segment to facilitate insertion and removal of the crankshaft bearing assembly from the power end frame assembly.
