Title: METHOD AND SYSTEM FOR PUMPING WATER FROM A FLEXIBLE TANK THROUGH INTERMEDIATE AIR BOX
Abstract:
A system that includes a flexible tank for transporting water with a flexible inner bag and discharge hole, a pump with pumping tube and an intermediate air box that has a water inlet, a water outlet, and an upper air opening. When connecting the pump to the water outlet and the flexible tank to the water inlet the water flows from the flexible tank into the intermediate air box until the water inlet and outlet are under the level of the water. The pump pumps the water from the intermediate air box and consequently from the flexible tank and when the flexible tank is emptied the water level in the intermediate air box drops under the level of the water outlet and consequently the pump pumps air that flow inside the intermediate air box through the upper air opening and therefore the flexible inner bag does not sucked outside.
