Abstract: Disclosed is a flanged manifold frack delivery system, or manifold assembly, for distributing fluids to a well wherein the assembly comprises at least one high pressure output studded or flanged connection in the absence of rubber seals. The high-pressure connection consists of cross-blocks and spools connected in series to each other. Described is a combination of high and low-pressure conduit configurations disposed along the length of the chassis; the high-pressure conduit assembly is made up using studded or flanged iron connections terminating at the opposite end to the low-pressure inlet with a studded or flanged iron connection so that a spool can be attached at the height of the well head to route the fluid to the well head. The assembly may be pre-fabricated to the user's needs and assembled on site, or may be mobile and delivered to the desired site for use.

Abstract: A singular piston included behind a valve seat within a gate valve assembly can be energized by external pressure through a hydraulic port within the valve body. When the back side of the singular piston is energized, the singular piston applies force in one direction against the adjacent valve seat, valve gate, opposing valve seat and valve seat pocket in both the valve open position and the valve closed position to block any unwanted matter from moving into the valve backside cavity. A singular piston has a pressure sealing surface and a piston pocket with an adjacent pressure sealing surface that allows the valve to seal in the closed position with the contained fluid bore pressure against the opposing valve body flow path side to the piston without the piston being energized.

Abstract: A method is disclosed for removing/installing both the upper and lower valve seat in a fluid end for a high-pressure pump with a plurality of horizontal plunger bores and an equal amount of vertical suction bores. Vertical suction bore contains a valve seat below the plunger bore and a valve seat above the plunger bore. The lower valve seat can pass through the upper valve seat pocket and be removed from fluid end via plunger bore opening.

Abstract: A fluid end for a high-pressure pump with a plurality of horizontal plunger bores that have an open end and a closed end for receiving a reciprocating plunger at its open end. The fluid end is provided with a corresponding number of vertical suction bores, each of which intersect one of the horizontal plunger bores and contains a valve seat below the plunger bore and a valve seat above the plunger bore. A suction manifold is fixedly attached to the bottom of the fluid end to provide a flow of fluid into the fluid end via the vertical suction bores. A high-pressure discharge bore intersects the vertical suction bore and receives fluid pressurized by the plungers via upper valves.
