Abstract: A flexible hose end fitting assembly includes a first portion defining a first fluid passageway and having a first end configured for coupling to a fluid conduit, a second portion defining a second fluid passageway and having a first end configured for coupling to a second end of the first portion and a second end configured for securely affixed to a flexible hose. A gasket is disposed in a groove formed in an interface between the first portion and the first end of the second portion of the assembly, and the first portion and the first end of the second portion of the assembly are securely fastened together by a plurality of threaded fasteners to form a continuous fluid passageway between the fluid conduit and the flexible hose.

Abstract: A positive displacement pump includes a suction cover disposed in a suction access bore defined in the fluid end and housing, where the suction cover is configured to cover the suction access bore. A retainer nut is configured for abutting against the suction cover and retaining the suction cover within the suction access bore. A suction gland has an inner circumferential threaded interface configured to engage an external circumferential threaded interface defined on the retainer nut, and the suction gland has a plurality of threaded openings configured to receive a plurality of threaded fasteners that can be used for securely fastening the suction gland to the fluid end housing.

Abstract: A suction cover assembly for a frac pump includes a suction cover having an annular base flange defining a sealing interface proximate to the base flange. The suction cover is dimensioned to be accommodated within a bore well of a fluid cylinder in the pump. An annular seal is seated on the sealing interface proximate to the base flange of the suction cover.

Abstract: A syringe assembly for a hydraulic fracturing system includes a syringe having a material chamber, a base fluid chamber, and a piston. The material chamber is configured to be fluidly connected to a fluid conduit. The piston retracts to draw material into the material chamber. The piston extends to push the material into the fluid conduit. The syringe assembly includes a diverter fluidly connected to the base fluid chamber and moveable between first and second positions. The first position of the diverter fluidly connects the base fluid chamber to a base fluid reservoir of the hydraulic fracturing system and fluidly disconnects the base fluid chamber from an outlet of a frac pump of the hydraulic fracturing system. The second position of the diverter fluidly connects the base fluid chamber to the outlet of the frac pump and fluidly disconnects the base fluid chamber from the base fluid reservoir.

Abstract: A fluid delivery device for a hydraulic fracturing system includes a fluid conduit having a fracking fluid outlet configured to be fluidly connected to a well head for delivering a fracking fluid to the well head. The fluid conduit includes a base fluid inlet configured to be fluidly connected to the outlet of a frac pump such that the fluid conduit is configured to receive a flow of base fluid from the frac pump. An injection system is fluidly connected to the fluid conduit downstream from the base fluid inlet and upstream from the fracking fluid outlet. The injection system is configured to be fluidly connected to a material source. The injection system is configured to inject at least one material of the fracking fluid from the material source into the fluid conduit downstream from the frac pump to generate the fracking fluid within the fluid conduit.

Abstract: A seat removal tool is disclosed for removing valve seats. A seat removal tool having a main rod, actuator rod within the main rod that actuates to cause radially expandable extraction segments to transition between an expanded position and a contracted position. When using the seat removal tool to remove a valve seat, portions of the radially expandable extraction segments may pass through a seat while the valve seat removal tool is in a contracted position. Thereafter, the seat removal tool may transition from the contracted position to an extended position, which grabs the seat. While in the expanded position, the seat removal tool may pull the valve seat from the passage.
