Durability needs to be incorporated into pump design to the handle the heavy use (and abuse). The India Mark II is a human-powered pump designed to lift water from a depth of 50–80 m. [1]
Where it is necessary to raise water to a height above that to which a suction or lift pump will operate effectively (about 7 metres), or to raise the pressure so that it will exit a nozzle with a strong force, such as through a fire hose, a force pump may be used. As with a suction pump, in its manual form it relies on an operator to pump a ...
The bush pump, also known as the Zimbabwe bush pump, is a positive displacement pump based on lever action [1] used to extract water from a bore hole well. It is the standard hand pump in Zimbabwe, and is used in Zimbabwe and Namibia. There are approximately 40 000 pumps (2009) [2] in Zimbabwe, and annually about 3000 pumps are installed. [3]
The device uses the water hammer effect to develop pressure that allows a portion of the input water that powers the pump to be lifted to a point higher than where the water originally started. The hydraulic ram is sometimes used in remote areas, where there is both a source of low-head hydropower and a need for pumping water to a destination ...
