<div>A '''rope pump''' is a kind of [[pump]] where a loose hanging rope is lowered down into a [[Water well|well]] and drawn up through a long pipe with the bottom immersed in water. On the rope, round disks or knots matching the diameter of the pipe are attached which pull the water to the surface.<br />

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 [[Water well|well]]. Rope pumps are often used in [[Developing country|developing areas]] with the most form consisting of a [[Polyvinyl chloride|PVC]] [[Plastic pressure pipe systems|pipe]] and a rope with flexible or rigid valves. Rope pumps are cheap to build and easy to maintain. One design of rope pump using a solar-powered rope pump can pump 3,000 litres per day using a 80 watt [[solar panel]] .<ref name=SolarAid/> Rope pumps can be powered by low speed petrol/diesel/engines, electricity<ref>{{cite web|url=http://www.daenvis.org/ropepump9.htm|title=Moto Rope pumps|accessdate=2009-04-10}}</ref>, human energy<ref name=thefarm/>, wind<ref>{{cite web|url=http://www.gamos.demon.co.uk/just%20gamos%20homepage/henkfnl2.htm|title=THE ROPE WIND PUMP|accessdate=2009-04-10}}</ref> and from solar.<ref name=SolarAid>{{cite web|url=http://www.solar-aid.org/project_water_pump/|title=Solar powered water pump|publisher=Soar Aid|accessdate=2009-04-10}}</ref><br />

==History==<br />
Chain or washer pumps were used by the [[China|Chinese]] over 1000 years ago. In the 1980's the first steps were made to improvement the rope pump using PVC pipes plastic moldings in [[Nicaragua]]<ref name=Ropepumphistory>{{cite web|url=http://www.ropepump.com/his/his.htm|title=history|publisher=Ropepump.com|accessdate=2009=04-10}}</ref>. The technology was rapidly disseminated over the whole country and 25% of the rural population in Nicaragua now use rope pumps. It is also used in other parts of Central America with over 25.000 pumps have been installed to date<ref>{{cite web|url=http://www.ropepump.com|title=history|publisher=Ropepump.com|accessdate=2009-04-10}}</ref> and is also being used in Africa<ref name=SolarAid/><br />

Rope pump technology is in the public domain and there are no patents pending on it.<ref name=Ropepumphistory/><br />
