Abstract
A piston is the driven component within a pump. The piston is driven along a longitudinal axis to pump a fluid through the pump. The fluid flows through the piston between an upstream end of the pump and a downstream end of the pump. The piston outputs the fluid into the downstream end of the pump at a vector offset from the longitudinal axis, thereby inducing rotation of the piston throughout the pumping process. Rotating the piston encourages even wear on various components within the pump, such as sealing rings surrounding the piston, thereby increasing the lifespan of the components and increasing the efficiency of the pump.
