    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 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.

    Abstract: In one aspect, there is provided a damper control system for a reciprocating pump assembly according to which control signals are sent to electromagnets. In another aspect, there is provided a method of dampening vibrations in a pump drivetrain according to which a beginning of torque variation is detected and at least a portion of the torque variation is negated. In another aspect, signals or data associated with pump characteristics are received from sensors, torque characteristics and damper response voltages per degree of crank angle are calculated, and control signals are sent to electromagnets. In another aspect, a damper system includes a fluid chamber configured to receive a magnetorheological fluid; a flywheel disposed at least partially within the fluid chamber and adapted to be operably coupled to a fluid pump crankshaft; and a magnetic device proximate the flywheel. The magnetic device applies a variable drag force to the flywheel.

    Abstract: According to one aspect, a manifold defines an internal region and a first inside surface. A fluid liner is permanently bonded to the first inside surface, and dynamically responds to pressure fluctuations within the internal region during fluid flow therethrough while the permanent bond is maintained. According to another aspect, an end cap is connected to the elongated member and defines a second inside surface. The fluid liner is engaged with each of first and second inside surfaces, and defines a third inside surface. A first thickness of the fluid liner is defined between the first and third inside surfaces, a second thickness of the fluid liner is defined between the second and third inside surfaces, and the second thickness is greater than the first thickness. According to another aspect, a plug opening is formed through the fluid liner, and a liner plug extends within the plug opening.
