ABSTRACT:
The present disclosure is directed to a water/air pumping system comprising essentially a substantially flat primary reservoir, a header tank and a pump. At least one reciprocating piston is powered through the tank. Eccentric drive cams are directly connected to the motor driven shaft and are connected to drive the pistons to pump water or air from the reservoir into the tank. A water and or air supply connection is horizontally connected to the reservoir and is provided with a water/air control valve proximate the reservoir. A tank discharge connector is connected to a water or air service system through the side wall of the tank externally thereof, above the motor driven shaft and its direct drive connection with the pistons for lubricating the driving mechanism. An air inlet valve is situated in the external wall of the primary reservoir beneath the piston intake so that the pump may pump either air or water.
