Abstract: A pump power end frame with a fatigue-resistant crankshaft housing machined from a one-piece forging may include machined features and bolted-on accessories. The crankshaft housing and the accessories have no welds that are subject to cracking in response to cyclic stresses due to operation of the pump.

Abstract: An anti-rotation system includes a plurality of key components, each sized and shaped to fit within and form a rotationally keyed relationship with a corresponding internal drive recess of a threaded retainer covering an access port in a fluid end of a pump; and a single locking bar that spans between and couples to each of the plurality of key components after the key components are fit within the corresponding internal drive recesses.
A method includes fitting each of a plurality of key components into a corresponding internal drive recess of a plurality of threaded retainers covering access ports in a fluid end of a pump, coupling a single locking bar to each of the plurality of key components to form an anti-rotation system; and inhibiting rotation of the plurality of threaded retainers during operation of the pump using the anti-rotation system.

Abstract: A pump power end includes an assembly comprising a crosshead, a connecting rod, and a joint. The joint may include a knuckle and a keeper. The connecting rod may include a forked end comprising two tines with a gap in the middle. The knuckle of the joint may be fixedly coupled to both tines. The crosshead may include a socket within which the knuckle of the joint is rotatably received. The keeper of the joint may include a body with a recess aligned with the socket to form a cavity within which the knuckle is disposed. The body of the keeper may be coupled to the crosshead and reside in the gap in the forked end of the connecting rod to retain the knuckle.
