An ozone injector device comprising a housing, a corona tube disposed within the housing and configured to generate ozone, a check-valve removably coupled to the water passageway, a second end of the check-valve having a cavity with a movable float contained therein, an ozone inlet fitting removably coupled to the check-valve, the ozone inlet being in fluid communication with the corona tube via a corona discharge tube such that ozone entering the water passageway through the ozone inlet fitting must pass through the check valve, and a spring-loaded clearing piston positioned to move into and out of the water passageway, the clearing piston being biased upwards, and configured to prevent flow of ozone into the water passageway.

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.

A pump fluid end having a reciprocating element a discharge valve assembly, a suction valve assembly, and a suction valve stop. The reciprocating element is disposed at least partially within a reciprocating element bore of the pump fluid end. The suction valve assembly is coupled with a front end of the reciprocating element. The suction valve stop is positioned within the reciprocating element bore such that the suction valve stop contacts and applies a closing force to the suction valve assembly when the suction valve assembly is stuck open at the end of a discharge stroke of the reciprocating element.

A gas transfer and depressurization system that is configured to transfer gas from a first location to a second location wherein during the transfer of gas the pressure of the first location is reduced. The gas transfer and depressurization system includes a drive chamber having an interior volume with a drive assembly movably disposed therein. A first cylinder and a second cylinder are operably coupled to the drive chamber on opposing sides thereof. The drive assembly includes a drive rod having portions extending into the first cylinder and second cylinder wherein the drive rod has pistons formed on opposing ends thereof. A controller is operably coupled to a compressed air source and is configured to provide compressed air into said drive chamber so as to reciprocally move the drive assembly. Gas blocks and coupling block are additionally present and facilitate flow of gas intermediate the first and second cylinders.

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 throughout the fluid end section.

A fluid end assembly comprising a plurality of fluid end sections positioned in a side-by-side relationship. Each fluid end section comprises a housing made of multiple-piece construction. One or more pieces of the housing are configured to have a plurality of stay rods attached thereto. The stay rods interconnect the fluid end assembly and a power end assembly.

An ozone injector device comprising a housing having a water passageway through the housing, a corona tube disposed within the housing, an ozone inlet fitting coupled to the water passageway, the ozone inlet being in fluid communication with the corona tube via a corona discharge tube, and a clearing piston positioned to move into and out of the water passageway directly opposite the ozone inlet. The clearing piston is biased upwards, towards to the ozone inlet, and configured to prevent flow of ozone into the water passageway.
