Abstract

See full text

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.
