A Rope pump can be used to draw water from large diameter hand dug wells of 3 meters to boreholes as small as 6 cm. One person can draw water up from 35 m deep, two persons can pump from 60 m deep (using a second crank) and if powered by an engine it can pump from 100 meters or more. A Rope pump can be driven by hand, bicycle, animals, wind or engines. If well made, a hand Rope pump delivers 35 litres / min from 10 meters depth and halve of that if the well is 20 metres deep. Hand pump models are most commonly used at depths less than 35m.
