However, the India Mark II Extra Deep pump can go up to 80 meters, so is considered to be a deep pump. They are all listed here, as they have similar design and maintenance needs.
====India Mark ll pump====
The India Mark II Pump is a robust conventional lever action handpump and is subject to Indian Standard IS 9301.. It is designed for heavy-duty use, serving communities of 300 persons. The maximum recommended lift is 50 m. The India Mark II is a public domain pump defined by Indian Standards and RWSN specifications. This pump has a pump head, pump stand and a handle of galvanised steel. This pump is not corrosion resistant and should not be used in areas with aggressive water ( pH value < 6.5).
It requires special skills for installation as well as for the maintenance, therefore it is not considered to be a VLOM pump. The pump body parts are Hot-Dip Galvanized and as such are extremely durable over the years.
====India Mark ll pump, Extra Deep====
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 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. 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). ====India Mark lll pump====The India Mark III Pump is a robust conventional lever action handpump for shallow to medium deep wells. It is designed for heavy-duty use, serving communities of 300 persons. The maximum recommended lift is 30 m. Besides the “Standard 63.5 mm” configuration, there exists a version with Ø50 mm cylinder size for lifts up to 50 m. Pump head, handle, water tank, pump stand and pump rods are made of galvanized steel, rising main of galvanized 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 aggressive water (pH value < 6.5). The India Mark III 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 foot valve without lifting the cylinder and the entire rising main (Ø 65 GI pipe). Cylinders are available in Ø50 mm and Ø62.5 mm.
The India Mark II Extra Deep well III Pump is a conventional lever action handpump public domain pump defined by Indian Standards and is subject to Indian Standard IS 15500 or to the RWSN Handpump Specification, Revspecifications. 2-2007. The down-hole components exist of a brass lined cast iron cylinder This pump requires special skills for installation 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 connectorsgood potential for community based maintenance.

====India Mark ll====
The Mark II is a closed-cylinder pump. 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. The top and bottom of the piston cylinder are “capped” with threaded reducers. The diameter of the pump cylinder is larger than the diameter of the riser main to which it is attached.
====India Mark ll pump, Extra Deep====
Pump head, handle, water tank, pump stand The down-hole components exist of a brass lined cast iron cylinder and pump rods are made the brass plunger has a triple cup seal of galvanised steel, Nitrile rubber. The rising main is of galvanised Ø 32 mm (1 ¼”) GI pipe, pump cylinder cast iron / brass, plunger and foot valve the pumprods are of brass. This pump is not corrosion resistant and should not be used in areas galvanised steel with aggressive water (pH value < 6.5)M12 connectors.
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).
The installation of the India Mark II Extra Deep well Pump pump need area mechanics that have attended special training and are well equipped with lifting tackle and comprehensive installation tools.
For maintaining this pump, special skills & tools are needed that exceeds the ability of a village caretaker. However, specifically trained area mechanics are able to maintain this pump.
==Manuals, videos==India Mark lll pump====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 manufacturers will be limited. The installation of the India Mark III Pump needs well-trained area mechanics with lifting tackle and links==comprehensive tool kit. Cylinder settings of more than 20 m are very heavy to handle.  * Do it yourself This pump has an improved "Community Management Potential” compared to the India Mark ll II, because the “open top cylinder” makes simpler maintenancepossible with less tools involved. ===Field experiences===<br>{|style="border: 2px solid #e0e0e0; width: 20%; text-align: justify; background-color: #e9f5fd;" cellpadding="2"<!--rsr logo here-->|- style="vertical-align: top"|[[Image:akvorsr logo_lite.png|center|60px|link=http://wwwakvo.cleanorg/products/rsr/]]<!--project blocks here--water>|-forstyle="vertical-laymenalign: bottom"|[[Image:project 1349.comjpg |thumb|center|140px|<font size="2"><center>[http:/support-files/idrcindiamarkiirsr.pdf IDRC India Mark II Manualakvo.org/project/1349/ RSR Project 1349] International Development Research Centre (IDRC)<br> Safe water for Wajir</center></font>|link=http://rsr. akvo.org/project/1349/ ]] |}
