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.
A pumpjack is the overground drive for a reciprocating piston pump in an oil well. [1] It is used to mechanically lift liquid out of the well if there is not enough bottom hole pressure for the liquid to flow all the way to the surface. The arrangement is often used for onshore wells. Pumpjacks are common in oil-rich areas.
Water pumping stations are differentiated from wastewater pumping stations in that they do not have to be sized to account for high peak flow rates. They have five general categories: [3] Source (such as a well) pump discharging into an elevated tank; Raw water pumping from a river or lake; In-line booster pumping into an elevated tank
Man cleaning a well in Yaoundé, Cameroon Hand pump to pump water from a well in a village near Chennai in India, where the well water might be polluted by nearby pit latrines. Shallow pumping wells can often supply drinking water at a very low cost. However, impurities from the surface easily reach shallow sources, which leads to a greater ...
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 ...

These pumps, often submersible and powered by electricity, can access water reserves located much deeper than shallow wells, ensuring a consistent supply even during periods of drought. They include different kinds of pumps, most of them submersible pumps: Hand pump, manually operated; Injector, a jet-driven pump; Mechanical or rotary lobe pump ...
