====India Mark ll pump, Extra Deep====
The India Mark II Extra Deep well Pump is designed for lifting water from extra deep water sources and is therefore strongly built. The maximal lift recommended is 80 m.
The India Mark II Extra Deep well Pump is a conventional lever action handpump and is subject to Indian Standard IS 15500 or to the RWSN Handpump Specification, Rev. 2-2007. The down-hole components exist of a brass lined cast iron cylinder and the brass plunger has a triple cup seal of Nitrile rubber. The rising main is of Ø 32 mm (1 ¼”) GI pipe and the pumprods are of galvanised steel with M12 connectors.

==Construction, operations and maintenance==
Maintenance on any part of the pump cylinder requires that the riser main and the pump rod be removed from the ground.The pump rod is galvanized steel and sections are threaded together. The pump cylinder is threaded onto the last section of riser main and is removed in its entirety as the last component to come out of the ground. The pump cylinder can then be unscrewed from the riser main. The top and bottom caps can be unscrewed from the cylinder body to gain access to the foot valve, the piston valve, the piston seals and anything else inside the cylinder body.
====India Mark ll pump, Extra Deep====
Pump head, handle, water tank, pump stand and pump rods are made of galvanised steel, rising main of galvanised GI pipe, pump cylinder cast iron / brass, plunger and foot valve of brass. This pump is not corrosion resistant and should not be used in areas with aggressive water (pH value < 6.5).
The reinforced “above ground components” have a potential for local manufacturing, but all other parts require a high degree of manufacturing quality that is presently not available in most of the African countries. Imported components however require a tight quality control in order to improve the lifetime of certain pump components considerably (wearing parts).
