2. Water pumping - Wikipedia

   en.wikipedia.org/wiki/Water_pumping

   The pumping of water is a basic and practical technique, far more practical than scooping it up with one's hands or lifting it in a hand-held bucket. This is true whether the water is drawn from a fresh source, moved to a needed location, purified, or used for irrigation, washing, or sewage treatment, or for evacuating water from an undesirable ...

3. Submersible pump - Wikipedia

   en.wikipedia.org/wiki/Submersible_pump

   A submersible pump (or electric submersible pump (ESP) is a device which has a hermetically sealed motor close-coupled to the pump body. The whole assembly is submerged in the fluid to be pumped. The main advantage of this type of pump is that it prevents pump cavitation, a problem associated with a high elevation difference between the pump ...

4. Chain pump - Wikipedia

   en.wikipedia.org/wiki/Chain_pump

   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 ...

   Arabic depiction of a piston pump, by Al-Jazari, c. 1206 [34] [35] First European depiction of a piston pump, by Taccola, c. 1450 [36] Irrigation is underway by pump-enabled extraction directly from the Gumti, seen in the background, in Comilla, Bangladesh. One sort of pump once common worldwide was a hand-powered water pump, or 'pitcher pump'.

6. Centrifugal pump - Wikipedia

   en.wikipedia.org/wiki/Centrifugal_pump

   Warman centrifugal pump in a coal preparation plant application. A pair of centrifugal pumps for circulating hot water within a hydronic heating system. Centrifugal pumps are used to transport fluids by the conversion of rotational kinetic energy to the hydrodynamic energy of the fluid flow. The rotational energy typically comes from an engine ...

7. Archimedes' screw - Wikipedia

   en.wikipedia.org/wiki/Archimedes'_screw

   The screw pump is the oldest positive displacement pump. [1] The first records of a water screw, or screw pump, date back to Hellenistic Egypt before the 3rd century BC. [1] [3] The Egyptian screw, used to lift water from the Nile, was composed of tubes wound round a cylinder; as the entire unit rotates, water is lifted within the spiral tube to the higher elevation.
