2. Hydraulic cylinder - Wikipedia

   en.wikipedia.org/wiki/Hydraulic_cylinder

   A hydraulic cylinder is the actuator or "motor" side of this system. The "generator" side of the hydraulic system is the hydraulic pump which delivers a fixed or regulated flow of oil to the hydraulic cylinder, to move the piston. There are three types of pump widely used: hydraulic hand pump, hydraulic air pump, and hydraulic electric pump.

3. Hand pump - Wikipedia

   en.wikipedia.org/wiki/Hand_pump

   The depth from which a hand pump will suck is limited by atmospheric pressure to an operating depth of less than 7 meters. [5] The height to which a hand pump will lift is governed by the ability of the pump and the operator to lift the weight in the delivery pipe.

4. Hydraulic machinery - Wikipedia

   en.wikipedia.org/wiki/Hydraulic_machinery

   Common types of hydraulic pumps to hydraulic machinery applications are: Gear pump: cheap, durable (especially in g-rotor form), simple. Less efficient, because they are constant (fixed) displacement, and mainly suitable for pressures below 20 MPa (3000 psi). Vane pump: cheap and simple, reliable. Good for higher-flow low-pressure output.

5. Pumpjack - Wikipedia

   en.wikipedia.org/wiki/Pumpjack

   A diagram of a pumpjack. 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.

6. 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 ...

7. Jack (device) - Wikipedia

   en.wikipedia.org/wiki/Jack_(device)

   A jack which can lift a mobile home. A jack is a mechanical lifting device used to apply great forces or lift heavy loads. A mechanical jack employs a screw thread for lifting heavy equipment. A hydraulic jack uses hydraulic power. [1] The most common form is a car jack, floor jack or garage jack, which lifts vehicles so that maintenance can be ...
