2. Hydraulic ram - Wikipedia

   en.wikipedia.org/wiki/Hydraulic_ram

   A hydraulic ram pump, ram pump, or hydram is a cyclic water pump powered by hydropower. ... Although the pump could in theory work without it, the efficiency would ...

3. Hydraulic pump - Wikipedia

   en.wikipedia.org/wiki/Hydraulic_pump

   Fluid flow in an external gear pump. A hydraulic pump is a mechanical source of power that converts mechanical power into hydraulic energy (hydrostatic energy i.e. flow, pressure). Hydraulic pumps are used in hydraulic drive systems and can be hydrostatic or hydrodynamic. They generate flow with enough power to overcome pressure induced by a ...

4. Priestly's Hydraulic Ram - Wikipedia

   en.wikipedia.org/wiki/Priestly's_Hydraulic_Ram

   The ram utilized the force of the falling water to pump the water up the cliff. Priestly started work on the project in 1888, intending to develop an irrigation system for the farmland south of Hagerman. The ram, although credited to Priestly, may have actually been built in 1901–02 by David Hyde.

   After the hike, though, I researched hydraulic ram pumps, called “hydrams,” and learned the mechanical water pumps are self-powered by the flow of water, via gravity, to the pump. Fast-flowing ...

6. Hydraulics - Wikipedia

   en.wikipedia.org/wiki/Hydraulics

   In Greco-Roman Egypt, the construction of the first hydraulic machine automata by Ctesibius (flourished c. 270 BC) and Hero of Alexandria (c. 10 – 80 AD) is notable. Hero describes several working machines using hydraulic power, such as the force pump, which is known from many Roman sites as having been used for raising water and in fire ...

7. Hydraulic accumulator - Wikipedia

   en.wikipedia.org/wiki/Hydraulic_accumulator

   A hydraulic accumulator is a pressure storage reservoir in which an incompressible hydraulic fluid is held under pressure that is applied by an external source of mechanical energy. The external source can be an engine, a spring , a raised weight , or a compressed gas .
