Abstract: A power end frame includes a plurality of rings cooperatively defining an interior of the power end frame configured to enclose a portion of a crankshaft of a power end of the reciprocating pump and a rod extending through each ring of the plurality of rings to couple each ring with an adjacent ring of the plurality of rings.

Abstract: According to one aspect, a power end of a high pressure reciprocating pump includes a first area and a second area. The first area includes at least a first component, and the second area includes at least a second component. The power end of the pump also includes a first lube arrangement configured to provide a first lube to the first area, and a second lube arrangement configured to provide a second lube to the second area. In one embodiment, the first lube has a higher viscosity than the second lube.

Abstract: A power end frame of a reciprocating pump includes a first ring, a second ring, and a plurality of connections extending between the first ring and the second ring. The first ring, the second ring, and the plurality of connections are integral with one another, and the plurality of connections includes a plurality of struts that form a plurality of open cells between the first ring and the second ring.

Abstract: A power end includes a monolithic core with a base having a surface configured to mount to a fluid end of the reciprocating pump and a plurality of extensions integral to the base. Each extension of the plurality of extensions includes a ring portion that defines an opening configured to receive a crankshaft of the reciprocating pump. The power end also includes a plurality of plates separate from the monolithic core. Each plate of the plurality of plates extends between a pair of adjacent of extensions of the plurality of extensions to enclose the monolithic core.

Abstract: Mounting a fluid end to a power end of a reciprocating pump involves the use of couplers, such as tie rods. A pump frame is structured so that multiple fluid end tie rod patterns can be machined into the nose plate of the power end of the pump. In one embodiment, not all patterns need to exist at the same time, and additional tie rod patterns can be added at a later time for retrofit to other patterns of tie rods.
