The Direct Action Handpumps are based on a buoyant pump rod that is directly articulated by the user, discharging water at the up- and down stroke. The pump head and the standing plate are made of galvanised steel and the handle of stainless steel. Pump rod and rising main are of HDPE or PVC pipes (with threaded connections) and the rest of the down-hole components are made of plastics. This makes these pumps completely corrosion resistant.
