Water-Powered Sling Pump Powers Itself LIVESTOCK Miscellaneous 17-2-29 That first-of-its-kind self-powered water pump from Sweden that we first told you about two years ago (Vol. 15, No. 3) is now on the market in the U.S. and Canada.
The "Sling Pump" pumps up to 2,000 gal. a day out of a stream as shallow as 10 in. with no outside power source at all. It consists of a hollow plastic cylinder with an aluminum propeller on front. A plastic 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. The flow of water turns the propeller and the cylinder, forcing the open end of the hose in and out of the water so that first air and then water are continually packed into the hose, pumping water out the end of the unit to wherever it's needed.
It'll pump water up to a mile away at about 8 psi and will even push it uphill as much as 82 vertical feet. It's virtually maintenance-free and will run for years without any repairs or maintenance whatsoever other than keeping it clean, says the U.S. importer Rajat Bhatnagar of Rife Hydraulic Engine Manufacturing Co.
The pump is 20 in. dia. and 33 in. long, weighs about 20 lbs., and is made out of plastic. It can be used on lakes, ponds and other non-moving bodies of water by attaching an optional wind-powered propeller.
Sells for $895 (pumps 800 gal. per day). Larger units, with capacities up to 4,000 gal. a day, are also available.
