Abstract
A grease/water pumping and separating system is provided with a pump mechanism that utilizes a motivating fluid to pump a grease/water mixture. The mixture is sucked into and discharged out of a pumping cavity. A movable biasing boundary, such as a piston, separates the motivating fluid from the grease/water mixture. The pump mechanism pumps the grease/water mixture to a separator unit which separates the grease and water components and directs the grease to a retaining tank and the gray water component of the grease/water mixture to an appropriate outlet.
