Pamir Pumps are conventional lever action handpumps. They are designed for heavy-duty use, serving communities of 300 persons. The maximum recommended lift is 60 m for the Pamir Pump. The pumps are not fully corrosion resistant; rods are subject to rusting. The Pamir Pumps are public domain pumps defined by RWSN specifications, only used in Afghanistan and Pakistan. They are 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.
