Abstract: A pump piston is disclosed. The pump piston may include a body having an actuating end, a pressurizing end opposite the actuating end, and an outer diameter that is greater at the pressurizing end than at the actuating end, wherein the outer diameter varies between the pressurizing end and the actuating end without increasing to form an outer diameter profile.

Abstract: A pump system includes a pump and a storage volume in fluid communication with a discharge port of the pump. The pump includes a housing defining a pump bore and a pump piston disposed in sliding engagement with the pump bore, the pump piston being in selective fluid communication with the discharge port of the pump. A method for operating the pump system includes determining a time to drain an amount of a first fluid from the storage volume, and retracting the pump piston within the pump bore at a target retraction rate based at least partly on the time to drain the first fluid from the storage volume.

Abstract: A pump is disclosed. The pump may include at least one pumping mechanism. The at least one pumping mechanism may include a barrel formed of a substrate having a bore and a plunger formed of a substrate and slidably disposed within the bore in the barrel. The pump may further include a coating disposed on the plunger. The coating may include a main layer containing a tribological material and a sacrificial break-in layer disposed on the main layer, the break-in layer containing a tribological material.
