2. Pump-jet - Wikipedia

   en.wikipedia.org/wiki/Pump-jet

   A pump-jet, hydrojet, or water jet is a marine system that produces a jet of water for propulsion. The mechanical arrangement may be a ducted propeller ( axial-flow pump ), a centrifugal pump , or a mixed flow pump which is a combination of both centrifugal and axial designs.

3. Maritime hydraulics in antiquity - Wikipedia

   The bilge pump was an improvement on the first hydraulic pumps used in antiquity: force pumps. Invented around the early 3rd century BCE, the most primitive design of a force pump consisted of a piston pushing water out of a tube, constructed by soldering individual bronze elements (Stein 246).

4. Pumpjack - Wikipedia

   en.wikipedia.org/wiki/Pumpjack

   The technology is simple, typically using a parallel-bar double-cam lift driven from a low-power electric motor, although the number of pumpjacks with stroke lengths 54 inches (1.4 m) and longer being used as water pumps is increasing. A short video recording of such a pump in action can be viewed on YouTube. [6]

5. Water pumping - Wikipedia

   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 ...

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 ...
