Abstract: Apparatus and method contemplating a high pressure flow device (such as 150, 230) having a body (such as 152, 232) defining a body bore (such as 154, 234) and defining a recess (such as 156, 240) in the body intersecting the body bore. A closure (such as 151, 236) is joined to the body and forms a sealing surface (such as 153, 237). A seal (such as 158, 242) 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.

Abstract: A flangeless fluid end comprising a fluid end body releasably attached to a connect plate. The connect plate is attached to a power source using stay rods. The flow bores of the fluid end are sealed without threading a retainer nut into the walls of each bore. Instead, the flow bores are sealed by bolting a retainer to the fluid end body. Plungers to drive fluid through the fluid end body are installed within removable stuffing box sleeves. These sleeves are maintained within the plunger bores by the bolted retainers. A number of features, including the location of seals within bore walls and carbide inserts within valve structures, aid in reducing or transferring wear.

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.

Abstract: A high pressure pump. The pump comprises a fluid end assembly supported on a power end assembly. The power end assembly is modular and held together by a first set of stay rods. The fluid end assembly comprises a plurality of fluid end sections positioned in a side-by-side relationship. Each fluid end section comprises a housing made of multiple-piece construction. One or more pieces of the housing are configured to having a second set of stay rods attached thereto. The second set of stay rods interconnect the fluid end assembly and a power end assembly and are vertically offset from the first set of stay rods.

Abstract: A system for cooling plungers which operate in high pressure pumps. The system uses a plunger having a blind bore formed therein. The blind bore may receive a number of different objects, some of which are fixed to the plunger. A heat exchanger may be installed within the blind bore. The heat exchanger may have internal passages or openings which allow for the circulation of fluid within the blind bore, thus cooling the plunger. The heat exchanger may be formed of a material having a higher thermal conductivity than the material used to form the plunger. This allows the heat exchanger to cool the plunger more effectively than if the plunger were solid or filled with an empty air space. The heat exchanger may be sealed within the bore of the plunger, or exposed.
