The present disclosure relates, to a wear-resistant hydraulic fracturing pump valve for use in a valve housing, the wear-resistant hydraulic fracturing pump valve comprising: (a) a valve head extending radially from a central axis, the valve head comprising: (i) a first bottom surface comprising a metal and positioned closest to a base of the valve head, wherein the first bottom surface is configured to form a metal seal with a top surface of a valve seat; and (ii) a first annular groove positioned directly adjacent and above the first bottom surface; and (b) a first wear-resistant pump valve gasket configured to mount inside the first annular groove and to form a valve gasket seal with the top surface of the valve seat.

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.

A dual circuit lubrication system for a power end of a reciprocating pump that includes a lubrication pump that supplies lubrication fluid to a high pressure lubrication circuit and a low pressure lubrication circuit. The high pressure lubrication circuit is fluidly coupled to a crankshaft to supply lubrication fluid to journal surfaces associated with the crankshaft at a first lubrication fluid pressure. The crankshaft drives a crosshead coupled to a plunger to displace fluid from a fluid end of the reciprocating pump. The low pressure lubrication circuit is fluidly coupled to supply the lubrication fluid to a plurality of roller bearing surfaces associated with the crankshaft at a second lubrication fluid pressure. The first lubrication fluid pressure is greater than the second lubrication fluid pressure.

A universal monitoring system applicable to a variety of hydraulic fracturing equipment includes an accelerometer mounted on a housing of a positive displacement pump and configured to sense a vibration associated with the positive displacement pump on start-up and generate a wake-up signal. A processor is communicatively coupled to the accelerometer and configured to initiate execution upon receiving the wake-up signal. A pressure strain gauge is mounted directly on the pump housing and is configured to sense deformity in the pump housing caused by alternating high and low pressures within the pump housing and generate sensor data. The processor is configured to receive the sensor data from the pressure strain gauge and configured to analyze the sensor data and determine a cycle count value for the positive displacement pump, and there is at least one communication interface coupled to the processor configured to transmit the sensor data and cycle count value to another device.

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.

A dual circuit lubrication system for a power end of a reciprocating pump that includes a lubrication pump that supplies lubrication fluid to a high pressure lubrication circuit and a low pressure lubrication circuit. The high pressure lubrication circuit is fluidly coupled to a crankshaft to supply lubrication fluid to sliding surfaces associated with the crankshaft at a first lubrication fluid pressure. The crankshaft drives a crosshead coupled to a plunger to displace fluid from a fluid end of the reciprocating pump. The low pressure lubrication circuit is fluidly coupled to supply the lubrication fluid to a plurality of rolling surfaces associated with the crankshaft at a second lubrication fluid pressure. The first lubrication fluid pressure is greater than the second lubrication fluid pressure.

A fluid end block for attachment to a power end of a high pressure reciprocating pump includes a main body portion having an outwardly facing body forward face, an outwardly facing body rear face opposite the body forward face, and opposing side surfaces. A web portion protrudes outwardly from the outwardly facing body forward face. The web portion may have an outwardly facing web forward face and a curvilinear side surface. The web portion may be integral with the main body portion. A plurality of bosses protrude from the web forward face and having a forward facing end. The plurality of bosses may be integral with the main body portion and the web portion. A plunger bore extends through one of the plurality of bosses configured to receive a reciprocating plunger.
