All the above mentioned components have a potential for local bad quailty manufacturing, as these parts needs advanced high quality machinery to produce, this is why number of manufacturers producing ISI mark pumps is very limited. Our company is one for the best and largest ISI mark hand pumps manufacturer, We only manufacturer high quality ISI mark Hand Pumps.
The installation of the India Mark II Pump need well trained area mechanics or a mobile team with lifting tackle and comprehensive tool kit.
This pump has limited “Community Management Potential”, but it is reliable and popular with the communities. To service the INDIA Mark II Pump skills and tools are needed which exceeds the ability of a village-level caretaker. However trained area mechanics can successfully maintain the pump.
