Natural Energy Water Pump: Revisit the Water Sling Pump

Most people who live in rural areas come from thelow income families. One reason for this is that the revenuegeneration is limited to certain domestic economic activities due topoor access to electricity. As a result, it limits the productivity ofthe people in these particular areas. By using this new pumpwhere sling pump concept is adopted, it is believe that the peoplein rural areas could have more access to electricity andsimultaneously grow the income related activities. This new pumpis capable of providing water supply to the domestic agricultureareas. Sling pump is the enhancement of the coil pump where itpowered by the water flow. This pump is driven by a propellerwhich finally resulting the entire pump to rotate the water andturns it into stream. Water and air enter the rear side of the pumpand are forced to flow through a coil of plastic tubes while thepump is rotating. Water will be channeled through a hose and intostock tank or reservoir. The pump is applicable for low head andlow flow river. From the experiment, this pump is capable todeliver up to 0.5m3 in a minute for stream water with flow rate5L/s.
