Description
The Afridev Pump is a conventional lever action handpump. The configuration includes an “open top” cylinder: the piston can be removed from the cylinder without dismantling the rising main. The foot valve is retractable with a fishing tool.
Material
Pump head, handle and pump stand are made of galvanised steel, pump rods
of stainless steel or of FRP rods (fibre glass reinforced plastic), rising main of PVC-U pipe (Ø 63 mm), cylinder of PVC-U pipe with brass liner (Ø 50 mm), plunger and foot valve are of brass or plastic. This pump is fully corrosion resistant.
Local manufacturing
All steel parts of this pump have a potential for local manufacturing. Local companies who manufacture PVC-U pipes and have the knowledge of processing engineering plastics are able to produce the “down-hole components”. Tooling cost are high and therefore the number of manufacturer will be limited.
