Air-Powered Water Pump

Air-Powered Water pump ENERGY Earth Energy 17-3-4 "It'll efficiently pump sandy or silty water that would otherwise wear out an electric submersible pump," says Paul Kunze, BDS Inc., Malta, Mont, about the company's new air-powered water pumping system that uses low pressure, low volume corn-pressed air to pump water from wells up to 200 ft. deep. The heart of the system is an expandable rubber sleeve that wraps around the water intake pipe. The sleeve is positioned inside the well casing near the top of the water level. To pump water, compressed air is pumped into the sleeve which expands to form a tight seal against the walls of the well casing. Pressurized air is then automatically diverted to the now-enclosed chamber that's created below the sleeve. Pressure forces water up into the intake hose and out the discharge line to the surface. Once the water level drops below the intake point, air flow is stopped and the sleeve retracts, allowing the well to recharge. "It eliminates the need to buy a new electric submersible pump every couple of years if you have sandy or silty water," says Kunze."If you have good, clean water it may not be an economical alternative. There are no expensive components on our system to plug up or wear out, and the rubber sleeve will last many thousands of pumping cycles. When it finally does fail, it can easily be replaced for about $60." Kunze says any 110-volt air compressor can be used. About 90 lbs. of air pressure will lift water 210 ft.
