__NOTOC__<small-title />
The Nira AF-85 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 Nira AF-85 is fully corrosion resistant. It is easy to install and has excellent potential for community-based maintenance. The Nira AF85 pump is not in the public domain. For specifications and information, it is necessary to contact the manufacturer.
All “down-hole components” are made of plastic with few rubber parts, which makes the installation easy (light-weight) and also the pump is completely corrosion resistant to aggressive waters.
===Suitable conditions===
This pump is like most of the “Direct Action Pumps” (DAP) limited to pumping lifts of a maximum of 15 m. It is not recommended, however, to go deeper than 12 m.
===Construction, operations and maintenance===
Pump head and standing plate are made of galvanised steel or painted with epoxy paint. The entire handle is made of stainless steel. Pump rods and rising main are made of HDPE pipe, plunger and foot valve of HDPE material. This makes the Nira AF-85 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 the foot valve and rising main. This pump is reliable and popular with the communities.
