A rope pump is a kind of pump where a loose hanging rope is lowered down into a well and stretched through a long pipe with the bottom submerged in water. In the rope, round discs or knots are connected that match the diameter of the pipe that pull the water to the surface. It is commonly used in developing countries for both community supply and self-sufficiency of water and can be installed in wells or wells dug by hand.
A rope pump is a type of pump whose main or most visible component is a continuous piece of rope, in which the rope is integral to lift water from a well. Rope pumps are often used in developing areas, the most common design of which uses PVC pipe and a rope with flexible or rigid valves. Rope pumps are inexpensive to build and easy to maintain. A rope pump design that uses a solar powered rope pump can pump 3,000 liters to 15 meters per day using an 80-watt solar panel. Rope pumps can be powered by low-speed gasoline / diesel engines, electricity, human energy, wind and solar power.
