    Abstract: A fluid end for use with a power end. The fluid end comprises a plurality of fluid end sections positioned adjacent one another. Each section includes a single horizontally positioned bore. A plunger is installed within the bore and includes a fluid passageway. Low-pressure fluid enters the bore through the plunger and high-pressure fluid exits the fluid end through an outlet valve installed within the bore. The intake of low-pressure fluid within the fluid end section is regulated by an inlet valve installed within the plunger. Low-pressure fluid enters the plunger through an inlet component attached to both the plunger and an inlet manifold.

    Abstract: A closure element for a fluid end assembly that has two or more recessed grooves formed in its outer surface. The grooves are axially offset. A seal is placed in one and only one of the grooves. As wear occurs, the seal is relocated to one of the other grooves. Instead of a series of axially offset grooves in a single closure element, a kit may be formed from two or more otherwise identical closure elements, each with a single recessed groove at a different axial position. Another closure element has a series of ledge-like surfaces defining spaces within which a seal may be received. One outer surface surrounds one or more of the other surfaces. A seal is placed in one and only one of the spaces. As wear occurs, the seal is relocated to one of the other spaces.

    Abstract: A high pressure swivel joint used in pipe assemblies transferring high pressure fluid. The swivel joint comprises a first pipe section and a sleeve-like second pipe section. The first pipe section is inserted into the second pipe section and the sections are relatively rotatable. A wear ring is positioned within a recess formed in the inner wall of the first pipe section. A second wear ring is positioned within a recess formed in the inner wall of the second pipe section.

    IPC: F04B53/22

    Abstract: A closure for a fluid end having a middle sealing section which engages a seal. The sealing section either has a larger outer diameter than adjacent sections or contacts a bore with a smaller inner diameter than adjacent sections. In either case, the clearance formed on either side of the sealing section reduces friction and allows the closure to be rocked back and forth to insert and remove the closure from the fluid end bore.

    IPC: F16K5/04

    Abstract: Apparatus and method contemplating a high pressure flow device having a body defining a body bore and defining a recess in the body intersecting the body bore. A closure is joined to the body and forms a sealing surface. A seal is mounted to the body in the recess and configured to extend from the recess beyond the body bore to seal against the sealing surface formed by the closure.
