__NOTOC__<small-title />
The Malda Pump is a direct action pump for Low Lift Wells. It uses a buoyant pump rod that helps to reduce the forces on the handle. It is designed for heavy-duty use, serving communities of 300 persons. The maximum recommended lift is 15 m. The Malda Pump is a public domain pump defined by RWSN specifications. The Malda Pump is fully corrosion resistant. It is easy to install and has excellent potential for community-based maintenance.
The Malda Pump as a direct action pump is based on a buoyant pump rod that is directly articulated by the user, discharging water during the up & down stroke.
===Suitable conditions===
The Malda Pump is specially designed for production in developing countries.
===Construction, operations and maintenance===
Pump stand, standing plate and handle are made of galvanised steel, wearing sleeve of stainless steel, pump rods and rising main of HDPE pipe and plunger & foot valve are also made of HDPE.
This makes the Malda Pump completely corrosion resistant.
This pump has an excellent “Community Management Potential”. Only simple tools are needed to pull out the entire pumping element as well as foot valve and rising main.
