The U3M Pump is a conventional lever action handpump developed in Uganda. It is designed for heavy-duty use, serving communities of up to 300 persons. The maximum recommended lift is 45 m.

The configuration includes an “open top” cylinder; the piston can be removed from the cylinder without dismantling the rising main. The footvalve is retractable with a fishing tool. The pump head has similar configurations as the INDIA Mark III Pump and the “down hole components” are similar to the Afridev components. The cylinder follows the Afridev Pump configuration. The plunger uses the 50 mm open top India MK III brass design.

The U3M Pump is a public domain pump defined by RWSN specifications. The U3M Pump is fully corrosion resistant. It is easy to install and has excellent potential for community based maintenance.
