What is a pedal pump?
Šlapetko is a simple suction pump driven by a human operator. These pumps are mainly used to pump water from subsurface tanks for irrigation, although they can certainly provide water for other uses. Pumps of this kind are relatively recent developments, but in Asia and Africa have entered the widespread use, where they provide cheap access to irrigation without the need for electricity or other industrial infrastructure.
The black pump consists of two runners, which on average five or six feet are mounted to the central swivel point. The operator controls both tendons attached to this pump using the same muscles that they would use to walk and the same walk. The soils attached to the treads are compressed by this movement and produce suction used to pump water from a nearby lake or stream or up from the borehole.
These pumps are very cheap and offer access to Irrigation Water for farmers and communities that could otherwise afford it. AlmostAll components of the pedal pump can be constructed from any robust materials that are locally available. Treads and supports can be made of metal, plastic, bamboo or other wood and replacement can be made relatively cheaply for parts that break. Only a small number of mechanical parts require more machining and these are simple and cheap.
The price of $ 20 to $ 80 USD Dollr (USD) of running pumps means that even very poor farmers can afford them. The purchase of the pump will increase agricultural productivity. These pumps are part of several plans to increase the ability of local farmers in poorer regions to be relatively self -sufficient and reduce the need to rely on more expensive or more energy -intensive technologies.
farmers use pedal pumps are often capable of growing other crops during the year or growing crops with higher cash ornourishment. The low price of such pumps means that the farmer can break even when investing in a pump on Šlapáště after only one or two successful irrigation periods.
Some factors reduce the usefulness of the hooker pumps. Such pumps can only pump water from shallow underground tanks and may not be suitable for use in areas where groundwater is deeper buried. Intensive irrigation can also exhaust underground water supply over time, which could further reduce the future usefulness of these pumps.
