摘要： 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 between an intake and discharge bore. The fluid routing plug comprises a plurality of first and second fluid passages. The first and second passages do not intersect and are offset from one another. The first fluid passages are configured to direct fluid delivered to the horizontal bore from intake bores towards a reciprocating plunger. The second fluid passages are configured to direct fluid pressurized by the plunger towards a discharge bore.

摘要： A lubricant pumping system includes a lubricant pump having a lubricant pumping space, a first seal configured to seal the lubricant pumping space, at least one signal detector, and a leakage detector for detecting leakage of a lubricant from the pumping space through the first seal and sending a signal to the signal detector in response to a detection of the leakage of the lubricant. The signal detector may produce a visual or acoustic output in response to receipt of the signal.

摘要： A diaphragm pump having a crankshaft that is rotatable about a rotational axis and coupled to a piston. The piston is reciprocally displaceable within a piston cylinder along an axis of motion between suction and discharge strokes. A diaphragm housing coupled to the piston cylinder at least partially defines a pumping chamber through which fluid is pumped as the piston reciprocates. The axis of motion, which intersects a connection between the piston and the connecting rod, may not intersect the rotational axis of the crankshaft such that, relative to an arrangement in which the axis of motion does intersect the rotational axis, a peak magnitude of piston side load forces during the discharge stroke is reduced and a peak magnitude of piston side load forces during the suction stroke is increased so as to attain an improved balance between the peak magnitudes of piston side load forces of the discharge and suction strokes.

摘要： A packing insertion tool for inserting a packing stack into a cylinder of a piston pump includes a packing holder on which the packing stack is mounted. The packing holder includes a body, a handle disposed at a first end of the body, and a plurality of fingers disposed at a second end of the body. The fingers extend axially from the body and the packing stack is mounted on the fingers, between the body and a retaining feature disposed at a distal end of the fingers. The fingers can flex to allow the diameter of the distal end of the fingers to change as the packing stack slides on to and off of the fingers.
