Direct Action Malda Hand Pump

Direct Action Malda Hand Pump
Direct Action Malda Handpump Structure


The Malda Pump as a Direct Action Handpump is based on a buoyant pump rod that is directly articulated by the user, discharging water at the up- and down stroke. The pump head, standing plate and the handle are made of galvanised steel. The sleeve, which protects the handle bar against wear, is made of stainless steel. Pump rod and rising main are of HDPE pipes and the rest of the down hole components are made of plastics. This makes this pump completely corrosion resistant.

The installation of the MALDA Pump is very easy and does not need any lifting equipment or special tools. The rising main with footvalve and pump head as well as the pump rod with handle and plunger can be assembled on the ground. When laid next to each other the correct length can be checked. For the installation both, the rising main and the pampered do not need to be dismantled again.


This pump has an excellent “Community Management Potential”. Only simple tools are needed to pull out the entire pumping element as well as the foot valve and rising main.


This pump is like most of the “Direct Action Pumps” (DAP) limited to pumping lifts of a maximum of 15 m. It is recommended not to go deeper than 12 m.
