As an example, the [[http://www.practicafoundation.nl Practica Foundation]] imports a low-cost two stroke, low power (1.5hp) engines from China, which has a fuel consumption of 0,5 litres/hour when pumping 3 l per second from 6m depth. The pump has a suction head of 7 meters depth with a maximum total head of 30 meters. The discharge is at maximum 25 cubic meters/hour, and the pump weighs 15 kilos. At 8 m depth the yield is 8 cubic meters per hour. It can be used to irrigate up to 1.5 ha of land. The price is 130-170 Euro, depending on the country of implementation.
