Abstract: A fluid end comprising a plurality of fluid end sections positioned in a side-by-side relationship. Each fluid end section is releasably attached to a connect plate. Each connect plate is attached to a power source using a plurality of stay rods. Each fluid end section comprises a housing in fluid communication with a pair of intake manifolds and a discharge conduit. A fluid routing plug is installed within each housing and is configured to route fluid throughout the housing. A plunger is installed within stuffing box attached to each housing. A number of features, including the location of seals within bore walls and carbide inserts within valve guides, aid in reducing or transferring wear.

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 assembly made of a plurality of fluid end sections positioned in a side-by-side relationship. Each fluid end section comprises a plurality of individual components joined together in a row. Two sets of fasteners are used to secure various components of each fluid end section together. When the fluid end section is assembled, a first set of fasteners is in a spaced relationship with and faces a second set of fasteners. At least one component making up the multi-piece fluid end section is configured to have a plurality of stay rods attached thereto. The stay rods interconnect the fluid end assembly and a power end assembly.

Abstract: A hybrid pressure seal for use in a plunger bore or a stuffing box used in a plunger bore. The hybrid seal has a first, inner seal made of a first, durable material. The inner seal has a cut-out formed in its outer surface in which an outer seal is placed. The inner seal may have features on its inner surface such as V-shaped protrusions or a D-shaped surface. The outer seal is elastomeric. One or more hybrid seals of different configurations may be used in a packing, disposed between a junk ring and a lantern ring. The lantern ring may be integral with and made of the same material as an adjacent hybrid seal.
