The No 6 Pump is lever operated Suction Handpump. Typically, No 6 Pumps are installed in collapsible tube wells with the screen extending to the coarse sand aquifer. The pump head and the handle are made of cast iron. Pump rod and axles are made of mild steel. The piston assembly is made of brass with a plastic bucket seal. The suction pipe and the robo screen are of PVC pipes. This makes this pump reasonably corrosion resistant.

The No 6 Pump has an excellent potential for local manufacturing.
The installation of the No 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 “Community Management Potential”. Only two spanners are needed to repair the plunger and the foot valve. A village caretaker can perform all maintenance operations.
This pump is like all Suction pumps limited to pumping lifts of a maximum of 8 m. It is recommended not to go deeper than 6-7 m. The No 6 Pump is not designed for a high daily output, but rather a family or small community pump.
