The Indus pump is a conventional lever action handpump. It is designed for heavy-duty use, serving communities of 300 persons. The maximum recommended lift is 45 m. The Indus pump is similar to the [[Kabul pump]] (a lighter version that is a more shallow pump) and the [[Pamir pump]] (a deeper pump).
The pump is not fully corrosion resistant; rods are subject to rusting. The Indus 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 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.
