===Suitable conditions===
A rope 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 boreholesmore. Applications include communal wellsA Rope pump can be driven by hand, bicycle, householdsanimals, irrigation wind or engines. If well made, a hand Rope pump delivers 35 litres / min from 10 meters depth and cattle wateringhalve of that if the well is 20 metres deep. Hand pump models are most commonly used at depths less than 35m.
One person can draw water up to 35 m, two persons can pump to 60m (using a second crank). A rope pump can be driven by hand, windmill, motor, bicycle, and animals. A rope pump can pump 40 litres / min from 10 meters depth. It is most commonly used at depths less than 50m. Some 70,000 rope Rope pumps are now in use in Nicaragua, 2010,000 in countries like Mexico, Honduras, Guatemala, El Salvadorand Bolivia. 30, 000 in African countries like Ethiopia, Ghana, Senegal, Tanzania, Zambia, Mozambique, Zimbabwe, Malawi and 6000 in Cambodia, and India, Vietnam, and others. In total, the Rope pump is used in over 30 25 countries. The pump can be used by single families, or up to 20 families (100 people).
The Rope pump is most suitable for single families, but is also often used for communities up to 20 families (150 people).

|-
| valign="top" | - Simple, no “black box” <br> - Easy to maintain <br>- Easy to train on production, maintenance- Can be made locally by workshops <br> - Significantly cheaper (up 5 to 5 8 times) cheaper than imported piston pumps. for the same depth <br> - If made wellRotating movement, one pump can supply up to 250 people as experiences no dynamic force like in Nicaragua, Ghana and other countries indicate. However, suggested use is for maximum of 20 families (100 people) piston pumps<br> - Easy to maintain. Pump parts in the wells plastic and concrete (no corrosion) <br> - Easy Rotating shaft, easy to train on maintenance. <br>- Can be made locally power by workshop. bicycle, animals, windmills, electric motors or combustion engines <br> - Ideal to be used by one or two families in a shallow well on their own yard. <br>- Can be used Fit for irrigation and , therefore used as income generation. <br>- Can be driven by handIf made well, windmillone pump can supply up to 250 people as is the experience in Nicaragua, motorTanzania, bicycleMalawi and other countries. However, animals. <br>suggested use is for maximum of 20 families (150 people) | valign="top" | - The rope pump It is simple which is easy good but also leads to copy, but bad copying (materials, construction) leads to resulting in early break down.and bad image <br>- Lack of Requires frequent maintenance and installation errorslike oiling the bushings, can lead if not leads to early wearing out or and breakage of pump partshandle <br>- A “blocking system” is needed on the handle to avoid return of the handle, if not the "spinning back" of the handle which can be dangerous, especially for children.<br>- It cannot pump higher than the pump outlet <br>- Compared to piston pumps the rope pumps Rope pump is semi-open at the top which in theory, can cause contamination of the well. (if well made this is hardly a problem in practice) <br> - The Rope pump splashes morethan piston pumps.<br>- Not suitable as a community pump for more communities larger than 20 families.<br>
