Design and construction of an improved rope pump for shallow wells
Abstract
The modern rope pump is based on the principle of the ancient chain pump. By making use of
new materials, it has been redesigned to provide a low-cost pump for water supply in rural areas
in developing countries. Its straightforward working principle and easy construction turn it into a
very effective pumping device, also in comparison with the piston pump and the centrifugal
pump. It can handle a range of pumping heights and volumes and is not sensitive to silt and
corrosion. Up to 100,000 of these pumps are in use worldwide, driven by human or animal
power, by an electric motor or fuel engine, and by wind power. The rope pump is now
recognized as one of the most promising solutions for rural water supply and sanitation.
Throughout the writing of this report, particular emphasis was placed on the design of the
submersible solar water pump. It also demonstrates how the rope pump will be constructed.
