Description

The INDIA Mark II Pump is a conventional lever action handpump and is subject to Indian Standard IS 9301. This pump has a pump head, pump stand and a handle of galvanised steel. The down hole components exist of a brass lined cast iron cylinder with a footvalve and a plunger of brass.
The plunger has a double nitrile rubber cup seal, the rising main is a Ø32 mm GI pipe and the pump rods are of galvanised steel with threaded connectors. 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, all 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 II Pump need well trained area mechanics or a mobile team with lifting tackle and comprehensive tool kit.
