The Kabul pump is a conventional lever action handpump. Parts of the Kabul and [[Afridev pump]] are the same and easily interchangeable. It is a pump designed for heavy-duty use, serving communities of 300 persons. The maximum recommended lift is 15 m. The pump is not fully corrosion resistant; rods are subject to rusting. The Kabul pump is a public domain pump defined by RWSN specifications, only used in Afghanistan and Pakistan. It is easy to install and have excellent potential for community-based maintenance.

The Kabul 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. Kabul body is slightly lighter than the [[Afridev pump]].

==Suitable conditions==
It is suitable for boreholes (with the same casing size as in the [[Afridev pump]]) and [[Traditional hand-dug wells]].<br>
Distribution: Tens of thousands in Pakistan & Afghanistan.

==Construction, operations and maintenance==
Pump head, handle and pump stand are made of galvanised steel, pump rods of mild steel, rising main of PVC-U pipe (Ø63 mm), cylinder of PVC-U pipe with brass liner (Ø50 mm), plunger and foot valve are of plastic.

All parts of this pump have a potential for local manufacturing in Afghanistan and Pakistan. Local companies who manufacture PVC-U pipes and have the knowledge of processing engineering plastics are able to produce the “down-hole components”. The cost of the tooling is high and therefore the number of manufacturer will be limited.
