Water Pump Powers Itself

Water pump powers itself ENERGY Alternative Fuels 15-5-22 First-of-its-kind self-powered water pump invented in Sweden made its debut at the New Zealand Fieldays. The JTM "Sling Pump" will pump as much as 4,000 gal. a day out of a stream less than 10 in. deep with no outside power source at all. It consists of a hollow plastic cylinder with an aluminum propeller mounted on front. A hose is coiled up inside the unit, covering the inside walls. The open end of the hose is positioned near the bottom of the cylinder, which fills up with water when anchored in a flowing stream or river. As the propeller turns the unit, the open end of the pipe alternately goes into the water and comes out of the water and then goes back in, so that first air and then water and then air are continually packed into the hose, pumping water out the end of the unit and to wherever it's needed. It'll pump water up to a mile away at about 8 psi. "It's totally maintenance-free. We've had units running for nearly 3 years and they've never been touched," says marketing manager Hans Carlberg. The pump is 18 in. in dia. and 32 in. long. It weighs about 20 lbs. and is made out of plastic. It can be used on lakes, ponds and other non-moving bodies of water with an optional wind-powered propeller. Sells for $500. Larger units that pump up to 9,000 gal. per day are also available.
