A 6 foot diameter wheel with 160 feet of 1-1\/4 inch inside diameter flexible polyethylene pipe is able to pump 3,900 gallons of water per day to a 40 foot head with a peripheral speed of 3 feet per second.<\/p>\n<p>With its low torque requirements, the pump is particularly suited to be mounted on and driven by a paddle wheel in a current of two feet per second or greater. This easily built, low maintenance spiral pump can be used to provide water without the need for fuel wherever there is a flowing stream or river. It can also be hand turned or otherwise driven to provide a low cost, efficient pump.&#8221;<\/p>\n<p>Read more: <a href=\"http:\/\/lurkertech.com\/water\/\/pump\/tailer\/\" target=\"_blank\">1<\/a> \/ <a href=\"http:\/\/www.wildwaterpower.com\/\" target=\"_blank\">2<\/a> \/ <a href=\"http:\/\/www.earthgarden.com.au\/waterwheel.html\" target=\"_blank\">3<\/a> \/ <a href=\"https:\/\/docs.google.com\/Doc?id=dc96jsvs_0fgspcgpk\" target=\"_blank\">4<\/a>.
