The RopePump, the latest manuals from Demotech and manuals from all over the world

Many manuals exist on how to make a rope pump. One of the best comes from Ghana, where Demotech worked on close cooperation with a team from the National Service Secretariat. Demotech's own manuals lag very much behind the state of the research in Demotech's own workshop, reason not to have renewed them up to now. However we feel higgly obliged to do so soon after the first field test of the latest version.
Please study our former manuals and the manuals we gathered from rope pumps worked at by other organizations.
