Hydraulic ram pumps and Sling Pumps

SWS Rower PumpsThe SWS Rower pump is a manuallyoperated, suction piston pump used fordrawing water from shallow wells, riverbed filters and open water. It is ideal forirrigation, village water supply andlivestock wateringSWS Filtration’s involvement with Rower Pumps started in 1982 when weintroduced them to an agricultural development project in North Nigeria.The Rower pump is most unusual in appearance. The cylinder is not uprightlike most pumps, but is placed into the ground at an angle of about 30o to thehorizontal so it looks more like a rocket launcher than a pump!The operator holds a wide T-handle and pullsand pushes directly on the piston rod as thewater pours out of the top of the cylinder sothe pumping action is like rowing a boat.Although when one first sees a Rower Pumpit looks rather weird, all of the main pumpcomponents are still present including atraditional foot valve, piston valve and pumpcylinder.Rower Pumps are very easy to make, operateand maintain. They are suction pumps so arelimited to areas where the water is within 6 metres or 20 ft of the surface. RowerPumps are ideal for lifting water from low level springs, shallow wells, or riverbeds. The Rower Pump does not filter the water itself, but it can be connected toa sub-sand filter. By drawing water directly from a protected low level spring, thewater will be much cleaner than if the spring is open for people and animals tocontaminate.http://ds.dial.pipex.com/swsfilt/rower/index.htm (1 of 2) [1/13/2005 12:46:26 PM]
