====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).
