  2. Backflow prevention device - Wikipedia

    en.wikipedia.org/wiki/Backflow_prevention_device

    Back pressure can force an undesirable contaminant to enter potable water piping. Sources of back pressure may be boilers, heat exchanging equipment, power washing equipment, fire sprinklers, or pumps in the water distribution system. In some cases there may be an almost continuous risk of overcoming the static water pressure in the piping.

    The demonstration pump exhibited at the Brussels exhibition was tested by Prof W.C Unwin in 1909 [5] and was found to require around 33% less fuel gas than would have been consumed had contemporary gas burning engines been used drive pumps moving the same amount of water to the same height. [2]

    en.wikipedia.org/wiki/Hand_pump

    Hand-powered force pump, with an air chamber to smooth out variations in flow rate. Hand pumps are manually operated pumps; they use human power and mechanical advantage to move fluids or air from one place to another. They are widely used in every country in the world for a variety of industrial, marine, irrigation and leisure activities.

    Due to the rotation, water is then picked up by the tube and pumped upwards in the hose. The coil pump, as many low lift pumps, is commonly used for irrigation purposes and for drainage of lands. It is currently still used by farmers in Asia. [1] The coil pump was built as an alternative to the Archimedean screw. Unlike the Archimedean screw ...

    en.wikipedia.org/wiki/Comparison_of_pumps

    Different types of pumps are suitable for different applications, for example: a pump's maximum lift height also determines the applications it can be used for. Low-lift pumps are only suitable for the pumping of surface water (e.g., irrigation, drainage of lands, ...), while high-lift pumps allow deep water pumping (e.g., potable water pumping ...

  7. Pumping station - Wikipedia

    en.wikipedia.org/wiki/Pumping_station

    Typically, water is channeled from a high-level reservoir to a low-level reservoir, through turbine generators that generate electricity. This is done when the station is required to generate power. During low-demand periods, such as overnight, the generators are reversed to become pumps that move the water back up to the top reservoir.
