Suitable conditions
The pump can be used by single families, or up to 20 families (100 people).
 {{procontable | proborder="1" cellpadding="5" cellspacing="0" align="center"|-! width="50%" style="background:#efefef;" | Advantages! style="background:#ffdead;" | Disadvantages|-| valign="top" | - Significantly cheaper (up to 5 times) than piston pumps. <br>
- If made well, one pump can supply up to 250 people as experiences in Nicaragua, Ghana and other countries indicate. However, suggested use is for maximum of 20 families (100 people) <br>
- Easy to maintain. <br>
- Can be used for irrigation and income generation. <br>
- Can be driven by hand, windmill, motor, bicycle, animals. <br>
 | convalign= "top" | - The rope pump is easy to copy, but bad copying (materials, construction) leads to early break down.
- Lack of maintenance and installation errors, can lead to early wearing out or breakage of pump parts<br>
- A “blocking system” is needed on the handle to avoid return of the handle, if not the "spinning back" of the handle can be dangerous, especially for children.<br>
- Compared to piston pumps the rope pumps splashes more.<br>
- Not suitable as a community pump for more than 20 families.<br>
