The Rower pump was developed as a simple manually operated pump for small scale irrigation. The Rower Pump is a suction pump in which the piston is directly activated. A surge chamber (an air vessel just downstream of the foot valve, makes the pumping op-eration is smoother). It is a simple and reliable pump with very few moving parts thus wear is reduced. It is easy to repair and main-tain The sitting position of the operator is ergonomically favourable and makes it easy to pump for prolonged periods, thus well suited for irrigation. The pump has limited use for drinking water as the spout is relatively low. Typically, Rower Pumps are installed in collapsible tube wells with the screen extending to the coarse sand aquifer.
All components are made from plastic; Surge chamber-blow moulded plastic, plunger and foot valve have rubber flap valves; rising main-PVC pipe with a Robo screen filter.
Installation and Maintenance
The installation of the Rower 6 pump is easy and does not need any lifting equipment or special tools. The drillers who sink the tube well with the sludger method also install the pump. This pump has an excellent potential for maintenance by the users. All repairs can be done without the use of tools.
