Description
The Direct Action Tara Handpump is based on a buoyant pump rod that is directly articulated by the user, discharging water at the up- and down stroke. TYPICALLY, TARA pumps are installed in collapsible tube wells with the screen extending to the coarse sand aquifer. The pump head and the handle are made of galvanised steel. Pump rod and rising main are of PVC pipes and the rest of the down hole components are made of rubber, plastic, stainless steel and brass. This makes this pump corrosion resistant. The TARA Pump is subject to Indian Standard IS 14106.

Installation
The installation of the TARA Pump is easy and does not need any lifting equipment or special tools. The drillers who sink the tube well with the “sludger method” also install the pump.
Maintenance
This pump has an excellent “Community Management Potential”. Only simple tools are needed to pull out the entire pumping element and the footvalve. A village caretaker can perform all maintenance operations.
Remarks
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. The TARA Pump is not designed for a high daily output, but rather a family or small community pump.
