A rope pump is a kind of pump of which the main or most visible component is a continuous piece of rope, in which the rope is integral in raising water from a well. Rope pumps are often used in developing areas. The most common rope pump consists of a PVC pipe and a rope. There are two types of rope pumps, namely valved and valveless. Valved rope pumps have either flexible valves (often made from rubber) or ridig valves (often metal or plastic washers. Rope pumps are cheap to build and easy to maintain.
Valveless rope pumps
Valveless rope pumps work on the principle of friction. The rope is dragged at high speed, and water which clings to the rope is dragged up the rope. Valveless pumps often use a bicycle to produce the required speed. It is a rather inefficient design but it requires no valves.[1]
