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 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: 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: Aparato y procedimiento que contemplan un dispositivo de flujo de alta presión (tal como 150, 230) que tiene un cuerpo (tal como 152, 232) que define una perforación de cuerpo (tal como 154, 234) y que define un rebaje (tal como 156, 240) en el cuerpo que se interseca con la perforación de cuerpo. Un cierre (tal como 151, 236) está unido al cuerpo y forma una superficie de sellado (tal como 153, 237). Una junta de estanqueidad (tal como 158, 242) está montada en el cuerpo en el rebaje y configurada para extenderse desde el rebaje más allá de la perforación de cuerpo para realizar un sellado con respecto a la superficie de sellado formada por el cierre.
