India Mark III Hand Pumps
The India Mark III VLOM deep well hand pumps’ design evolved to replace the India Mark II in remote locations where special tools were rarely found. Conforming to IS: 15500-2004 standard, India Mark III hand pump has open top cylinder (OTC), which facilitates pulling out of plunger assembly. It also assists in changing valve assembly from the cylinder without pulling out the water cylinder and riser pipes. These pumps are modified versions of India Mark II hand pumps; moreover G.I. pipes measuring 65/50 NB in diameter are used in this pump. Use of the VLOM pump thus reduces requirement of heavy tools, users including women can be trained for the repairs. Hence it is named as (VLOM) Village Level Operation Maintenance pump.
