Abstract
A submersible pneumatic canister pump system for pumping liquid from a tank or underground location by incorporating a floating ball valve inside the pump for preventing air from exiting with the liquid discharge. The floating ball valve is located near the lower end of the pump and communicates with the discharge pipe. When liquid level approaches the lower end of the pump a ball of lighter density than the liquid rests on a seat and prevents further discharge of liquid and the passage of air out of the pump. Also shown are various pump control arrangements that can be used to operate the pump.
