Description
The INDIA Mark III Pump is a conventional lever action handpump and is subject to Indian Standard IS 13056. This pump has similar configurations as the INDIA Mark II, only the “down hole components” were changed in order to improve the village level maintenance. The most important improvement is the “open top cylinder”, which makes it possible to remove the plunger and also the footvalve without lifting the cylinder and the rising main (Ø65 GI pipe). This pump is not corrosion resistant and should not be used in areas with aggressive water (pH value < 6.5).

Local manufacturing
All “above ground components” have a potential for local manufacturing, the other parts need a high degree of quality control to ensure a reliable operation. The cost of the tooling requirement is substantial and therefore the number of manufacturer will be limited.
Installation
The installation of the INDIA Mark III Pump needs well-trained area mechanics or a mobile team with lifting tackle and comprehensive tool kit. Pump cylinder settings of more than 30 m are difficult, because of weight of the rising main.
Maintenance
This pump has an improved Community Management Potential” compared to the INDIA Mark II, because the “open top cylinder” gives the possibility of a simpler maintenance with less tools involved.
