    en.wikipedia.org/wiki/Hand_pump

    A chain pump is a type of water pump that uses a chain to move water from one place to another. It works on the principle of a continuous loop of chain moving through a series of sprockets, with attached buckets that lift water as the chain passes over the top sprocket and discharge it as the chain reaches the bottom.

  3. Water pumping - Wikipedia

    en.wikipedia.org/wiki/Water_pumping

    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 ...

  5. Village-level operation and maintenance (pumps) - Wikipedia

    en.wikipedia.org/wiki/Village-level_operation...

    During the first UN decade on water boreholes, hand-dug wells and tubewells were constructed and water pumps were provided to developing countries by various NGOs. Unfortunately this top down approach led to the installation of pumps, notable the India Mark II, that were difficult to maintain. VLOM pumps were designed to allow remote villages ...

  6. Hydraulic ram - Wikipedia

    en.wikipedia.org/wiki/Hydraulic_ram

    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 ...

  7. Pressure tank - Wikipedia

    en.wikipedia.org/wiki/Pressure_tank

    A simple control system for a water well. Referring to the figure on the left, a submersible water pump is installed in a well. The pressure switch turns the water pump on when it senses a pressure that is less than P lo and turns it off when it senses a pressure greater than P hi. While the pump is on, the pressure tank fills up.

  8. Water-returning engine - Wikipedia

    en.wikipedia.org/wiki/Water-returning_engine

    A water-returning engine was an early form of stationary steam engine, developed at the start of the Industrial Revolution in the middle of the 18th century. The first beam engines did not generate power by rotating a shaft but were developed as water pumps, mostly for draining mines.

  9. Chain pump - Wikipedia

    en.wikipedia.org/wiki/Chain_pump

    The chain pump is type of a water pump in which several circular discs are positioned on an endless chain. One part of the chain dips into the water, and the chain runs through a tube, slightly bigger than the diameter of the discs. As the chain is drawn up the tube, water becomes trapped between the discs and is lifted to and discharged at the ...
