    Abstract: A fluid routing plug for use with a fluid end section. The fluid end section being one of a plurality of fluid end sections making up a fluid end side of a high pressure pump. The fluid routing plug is installed within a horizontal bore formed in a fluid end section and is configured to route fluid between an intake and discharge bore. The fluid routing plug comprises a plurality of first and second fluid passages. The first and second passages do not intersect and are offset from one another. The first fluid passages are configured to direct fluid delivered to the horizontal bore from intake bores towards a reciprocating plunger. The second fluid passages are configured to direct fluid pressurized by the plunger towards a discharge bore.

    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 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.
