Abstract: A valve seat for a valve assembly for a high-pressure fluid pump is disclosed. The valve assembly includes a valve body, and a valve seat fabricated of a first material. The valve seat has a generally a tubular body having an annular collar having an outer diameter surface extending beyond the outer diameter surface of the tubular body, and an annular insert fabricated of a second material more durable than the first material and affixed to form an inner diameter surface of the collar, the insert forming an annular sealing surface against which the valve body abuts when in a closed position. The insert forms an annular ledge edge at its inner diameter surface that is offset from the inner diameter surface of the tubular body to form an annular chamfered edge.

Abstract: A linear frac pump includes a fluid end having an inlet valve disposed proximate to an inlet port, and a discharge valve disposed proximate to a discharge port. The pump further includes a first plunger rod housed within a first plunger housing, the first plunger rod having first and second ends, the first end being in fluid communication with the fluid end, and the second end being coupled to a first actuator. The pump includes a second plunger rod housed within a plunger housing, the second plunger rod having first and second ends, the first end being in fluid communication with the fluid end, and the second end being coupled to a second actuator. The first and second plunger rods and housings are coupled to the fluid end and the first and second plunger rods operate in sync to drive fluids inward from the inlet port and outward via the discharge port being regulated by the inlet and discharge valves.

Abstract: A reciprocating pump for a hydraulic fracking operation includes a plunger mechanically connected to a crankshaft for pumping a fluid through a cylinder, the cylinder having fluid ports for ingress and egress of fluid. An ingress valve is disposed at the ingress port, and a first actuator is coupled to the ingress valve and configured to actuate the ingress valve to be displaced between an enlarged open position to permit fluid flow through the ingress port and a closed position to prohibit fluid flow through the ingress port. An egress valve is disposed at the egress port, and a second actuator is coupled to the egress valve configured to actuate the egress valve to be displaced between an enlarged open position to permit fluid flow through the egress port and a closed position to prohibit fluid flow through the egress port.

Abstract: A valve member for a reciprocating pump includes a valve head that is configured to move relative to a valve seat of the reciprocating pump between an open position and a closed position. The valve head includes a body, and an insert held by the body. The insert defines at least a portion of a strike face that is configured to contact the valve seat when the valve head is in the closed position. The valve head includes a seal held by the insert. The seal is configured to sealingly engage the valve seat when the valve head is in the closed position.

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.
