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 fluid end section having a clamping system. The clamping system has a primary clamp formed of a number of sections, which, disposed in end-to-end arrangement, form an annular ring. The primary clamp has an angled surface at each of two rims, which interact with complementary surfaces on flanges that form two separate components of the fluid end section. Each of the two separate components have a bore, which when aligned by placement of the clamp, are in alignment with one another. The clamp has an externally-disposed compression ring, which may either be essentially the width of the primary clamp, or may have one or more flexible rods which interact with grooves on the primary clamp. In either case, the compression ring holds the primary clamp in place, therefore joining the components of the fluid end.
