==Suitable Conditions==
The EMAS pump is designed for household water supply at family level. Large diameter models can be used for small scale irrigation if the water is very superficial.
Several variants of the EMAS pump exist, such as adaptations to shallow wells (larger diameter, higher output), very high pressure (up to 60 m head) and foot-operated balancing devices. It can be coupled to windmills, children's seesaws, animal roundabouts etc. An EMAS pump can fit in boreholes as narrow as 1.25", which means that cheap, hand drilled boreholes are possible, such as with the [[Jetting - EMAS method]].
EMAS pumps can be used to pump to a depth of 40-50 m. Deeper than 40-50 m, the pumping becomes very heavy. The EMAS pump can pump up to 30 l/min from a depth of 10 m, when operated by hand. Total production is up to about 5 m4/day. (That is: 5 m3 from 1 m depth or 0.5 m3 from 10 m or 250 l/day from 20 m depth etc.).
The lifespan of an EMAS pump can be estimated as 2 million liters pumped. PVC pumps are not as sturdy as metal ones. Ideally, they should serve a single family who owns and maintains it. Communal use is possible if maintenance and repair are well organized, but a single pump is not recommended to serve more than 100 people.
