The most prevalent hydraulic pump used in maritime situations in ancient Rome was the bilge pump, which functioned to siphon collected water out of a ship's hull (Oleson 1984). The bilge pump was an improvement on the first hydraulic pumps used in antiquity: force pumps.
The device then appeared in ancient Egypt from about 200 B.C., featuring a pair of gear-wheels [dubious – discuss]. [2] A version of the chain pump was used in ancient Greece and Rome, sometimes with pots, or scoops fixed to the chain, which, as they passed over the top pulley, tipped the water out; a 2nd-century example is preserved in ...
The term saqiyah or saqiya is the usual term for water-raising devices powered by animals. [13] The term noria is commonly used for devices which use the power of moving water to turn the wheel instead. [14] Other types of similar devices are grouped under the name of chain pumps. A noria in
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.
In 1828, Ányos Jedlik, a Hungarian who invented an early electric motor, constructed a tiny model car powered by his new motor. [8] In 1834, Vermont blacksmith Thomas Davenport, the inventor of the first American DC electric motor, installed his motor in a small model car, which he operated on a short circular electrified track.

P2 (on the right in the picture) from the top of the air supply container (C) to the top of the water supply container (B) P3 (in the middle of the picture) from the bottom of the water supply container (B), up through the bottom of the basin (A) to a height above the basin's rim. The fountain issues upwards through this pipe.
Musicians with cornua and a water organ, detail from the Zliten mosaic, 2nd century CE. The water organ or hydraulic organ (Greek: ὕδραυλις) (early types are sometimes called hydraulos, hydraulus or hydraula) is a type of pipe organ blown by air, where the power source pushing the air is derived by water from a natural source (e.g. by a waterfall) or by a manual pump.
Water was admitted into a reinforced barrel from a cistern, and then a valve was opened to admit steam from a separate boiler. The pressure built over the top of the water, driving it up a pipe. [19] He installed his steam-powered device on the wall of the Great Tower at Raglan Castle to supply water through the tower. The grooves in the wall ...
