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.

Abstract: According to one aspect, a manifold defines an internal region and a first inside surface. A fluid liner is permanently bonded to the first inside surface, and dynamically responds to pressure fluctuations within the internal region during fluid flow therethrough while the permanent bond is maintained. According to another aspect, an end cap is connected to the elongated member and defines a second inside surface. The fluid liner is engaged with each of first and second inside surfaces, and defines a third inside surface. A first thickness of the fluid liner is defined between the first and third inside surfaces, a second thickness of the fluid liner is defined between the second and third inside surfaces, and the second thickness is greater than the first thickness. According to another aspect, a plug opening is formed through the fluid liner, and a liner plug extends within the plug opening.

Abstract: A valve has a body having a rotatable valve element. A drive mechanism has a drive input member and a drive output member that are coupled to the valve element for rotating the valve element. A shear member is operatively located within the drive mechanism between the drive input member and the drive output member for shearing in the event the force to rotate the valve element is excessive. The valve has indicia indicating open and closed positions for the valve element An indicator is mounted to output drive member to properly align with the indicia regardless whether the shear member has sheared or not.

Abstract: A check valve assembly has a body having a central cavity intersected by upstream and downstream flow passages. A seat is secured by a threaded engagement in the upstream flow passage. An access bore intersects the cavity and has a support shoulder formed in it. A holder is supported on the support shoulder. A flapper is pivotally secured to the holder and located in the cavity for movement between an open position and a closed position blocking flow through the seat. A straight edge portion in the access bore engages a straight edge portion of the holder to prevent rotation of the holder. A fastener extends through a hole in the support shoulder into engagement with the seat to prevent rotation of the seat.

Abstract: A dual circuit lubrication system for a power end of a reciprocating pump that includes a lubrication pump that supplies lubrication fluid to a high pressure lubrication circuit and a low pressure lubrication circuit. The high pressure lubrication circuit is fluidly coupled to a crankshaft to supply lubrication fluid to sliding surfaces associated with the crankshaft at a first lubrication fluid pressure. The crankshaft drives a crosshead coupled to a plunger to displace fluid from a fluid end of the reciprocating pump. The low pressure lubrication circuit is fluidly coupled to supply the lubrication fluid to a plurality of rolling surfaces associated with the crankshaft at a second lubrication fluid pressure. The first lubrication fluid pressure is greater than the second lubrication fluid pressure.

Abstract: A seal assembly is disposed in an annular recess in a cylinder chamber between a pump cavity and a pump exterior. The seal assembly includes a main seal and a back-up seal and seals to a pump plunger disposed within the cylinder chamber. The back-up seal includes an extrusion recess extending from a surface of the back-up seal adjacent the main seal along an inner or an outer diameter of the back-up seal. During pumping operations the plunger strokes through the cylinder chamber causing the main seal to extrude into the extrusion recess to form a seal between the plunger and the cylinder chamber.
