    Abstract: A valve seat at least partially formed of a ceramic material for use in a fracturing pump includes a first body and a second body. The first body is configured to be inserted into a fluid passageway of the fracturing pump. The first body has an outer diameter, D1. The second body extends radially from the first body and has an outer diameter, D2, greater than the outer diameter, D1, of the first body. The second body is at least partially formed of the ceramic material.

    Abstract: 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.

    Abstract: A power end frame assembly for a reciprocating pump that includes a first and second end plate segment each including annular bearing support surfaces configured to support a crankshaft bearing assembly. At least one middle plate segment is disposed between the first and second end plate segments and includes an annular bearing support surface configured to support a crankshaft bearing assembly. The annular bearing support surfaces of the first and second end plate segments and the at least one middle plate segment each have a diameter and are coaxially aligned. The diameter of at least one of the first and second end plate segments is different from the diameter of the at least one middle plate segment to facilitate insertion and removal of the crankshaft bearing assembly from the power end frame assembly.

    Abstract: A valve assembly for use in a fracturing pump including a valve member movable into and out of engagement with a valve seat body. The valve seat body includes an outer surface and an inner surface, the inner surface forming a fluid bore extending between a first end and a second end of the valve seat body. The body further includes a seating surface extending radially from the inner surface and facing the valve member, the seating surface having a recessed area. An insert is disposed in the recessed area forming at least a portion of the inner surface and at least portion of the seating surface. The valve seat body first end has a diameter different from a diameter valve seat body second. The difference between diameters allows the valve seat body outer surface to be supported by the fluid passageway.
