Description
The AFRIDEV Pump is a conventional lever action handpump. The configuration includes an open top cylinder, i.e. the piston can be removed from the cylinder without dismantling the rising main. The footvalve is retractable with a fishing tool. The riser pipes are made of u-PVC. The pump rods are of stainless- or mild steel with hook and eye connectors, allowing removal without tools. Engineering plastics like POM and PA 66 are used for the pumping elements, plunger/footvalve and for the bearings. This pump is corrosion resistant in the stainless steel rod configuration.

Local manufacturing
All steel parts of this pump have a potential for local manufacturing. Local companies who manufacture u-PVC pipes and have the knowledge of processing engineering plastics are able to produce the “down hole components”. The cost of the tooling requirement is substantial and therefore the number of manufacturer will be Limited.
Installation
The installation of the AFRIDEV Pump is not difficult and does not need any lifting equipment.
Maintenance
This pump has an excellent “Community Management Potential”, it is reliable, easy to repair by a village caretaker and popular with the communities. The only tools needed are one spanner and the fishing tool.
