Abstract: A segmented fluid end module comprises a first, second, and third body each comprising a bore formed therethrough. The first body is coupled to an upper end of the second body by a first plurality of fasteners that extend through the first body. The bore of the first body is in fluid communication with the bore of the second body. The third body is coupled to a side of the second body by a second plurality of fasteners that extend through the third body. The bore of the third body is in fluid communication with the bore of the second body. A pump system comprises the segmented fluid end module, a suction manifold coupled to the first body, a discharge manifold coupled to the third body, and a power end comprising a plunger that extends into the second body.

Abstract: Aspects of the present disclosure relate to locking assembly apparatus for piston apparatus and pony rod apparatus of pump systems (such as mud or frac pump systems), and related methods. In one aspect, the locking assembly is a mechanical locking assembly used to quickly and simply lock and unlock (e.g., release) a piston apparatus to and from a pony rod apparatus.

Abstract: A washpipe assembly is configured to form a fluid tight seal between a rotating and non-rotating component. The washpipe assembly has a washpipe, a static seal assembly coupled to one end of the washpipe, and a dynamic seal assembly coupled to an opposite end of the washpipe. The dynamic seal has a seal disposed within an outer housing. The seal is contained within a seal cavity formed by the outer housing and an outer diameter of the washpipe. The dynamic seal assembly is rotatable relative to the washpipe while the seal maintains sealing contact with the outer diameter of the washpipe.

Abstract: Aspects of the present disclosure relate to reciprocating pumps, and specifically to power end rod assemblies, for pumping operations such as wellbore fracturing or drilling operations. The power end rod assembly comprises a power end rod comprising a body, a flanged end portion, and a shank portion. A wear plate is removably coupled to the shank portion by a securing member.

Abstract: The present disclosure relates to safety devices, locking assemblies, fluid ends, and related methods for pumping operations. One safety device for fluid ends includes a valve cover including an outer shoulder and a receptacle opening, and a jam structure movable in the receptacle opening of the valve cover. The jam structure includes a first plate, a second plate, a rod between the first plate and the second plate, and one or more extensions extending relative to the second plate. Another safety device includes one or more locking plates configured to prevent opening of the fluid end when under pressure.

Abstract: A safety device coupled to a fluid end such that the safety device is in fluid communication with at least one of a suction chamber and a discharge chamber of the fluid end. The safety device has an outer housing and a visual indicator. The visual indicator is moveable between a first position where the visual indicator is retracted into the outer housing, and a second position where the visual indicator is extended out of the outer housing.

Abstract: Embodiments disclosed herein generally relate to a system and method for tensioning a bolt. The bolt tensioning system may be used with variable length connection members, for example studs, in any one or more of the drilling, subsea, and process industries to couple a first member to a second member. The bolt tensioning system may remain coupled to the first member and the second member, while applying tension to all of the bolts at the same time, rather than having to torque or tension each bolt individually. The bolt system may accurately and uniformly tension all bolts in a single operation to provide reliable connections.

Abstract: A screw gland assembly that comprises a body having threads formed on an outer surface of the body. A piston retainer coupled to the body, and a piston disposed within the body. A biasing member disposed between the piston retainer and the piston such that the piston is moveable relative to the body against a bias force of the biasing member.

Abstract: A cartridge retention system includes a retention body, a cartridge assembly, and a retaining flange. The cartridge assembly has a housing coupled to the retention body, a biasing member disposed within the housing, and a piston biased by the biasing member toward the retention body. The retaining flange is coupled to the retention body by the cartridge assembly.

Abstract: A valve cover assembly and a liner retainer assembly configured to retain a plug, a liner, and/or a liner seal within or against a module or retention body of a fluid end of a pump. The valve cover assembly and the liner retainer assembly include pistons coupled to a retaining flange or a threaded gland. A bias applied to the pistons biases the retaining flange and a threaded gland that is coupled to the retaining flange, or the piston alone, into engagement with the module or retention body to retain the plug, the liner, and/or the liner seal on the module.

Abstract: The present invention includes a variety of methods for rearranging symbols in a symbol matrix by displaying the rotation of symbols around a common point. In a preferred embodiment, each symbol rotates along its own path around a common point located in the center of the matrix. In another preferred embodiment, the common point around which the symbols rotate is represented by an object formed by the symbol set, such that all symbols used in the game are component parts of the common point.
