Hand pump

From Wikipedia, the free encyclopedia

This article is about hand-powered water pumps. For beer handpumps, see beer engine.

Handpumps are used primarily in developing nations as a manually powered means of bringing water to the surface from a borehole, rainwater tank or well.

The main types of traditional hand pumps are the India Mark II, the India Mark III, and the Afridev deep-well (30 - 40 m deep) pumps. However, these pumps cannot pump from very deep and require many spare parts that are often not available locally in developing countries. Often these pump are therefore disfunctional within a few years. New, spare parts free handpumps are being developed that can also pump from up to 100 m deep, like the Afripump^[1].

Village Level Operation and Maintenance (VLOM) refers to low maintenance handpumps which can be maintained at a village level, intended to provide reliable long-term service.

Thousands of handpumps have been installed in developing countries of the last two decades, especially in India, Bangladesh, and Sub-Sahara Africa. Lately, appropriate technology organisations as Practical Action are supplying information on how to build/set-up (diy) handpumps and treadle pumps in practice.^{[2] [3]}

They can be used in gardening too.
