2. 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 ...

3. Pump - Wikipedia

   en.wikipedia.org/wiki/Pump

   A small, electrically powered pump A large, electrically driven pump for waterworks near the Hengsteysee, Germany. A pump is a device that moves fluids (liquids or gases), or sometimes slurries, [1] by mechanical action, typically converted from electrical energy into hydraulic or pneumatic energy.

4. Thermal hydraulics - Wikipedia

   en.wikipedia.org/wiki/Thermal_hydraulics

   An example of single-phase heat transfer is a gas-cooled reactor and molten-salt reactor. The most convenient way for characterizing the single-phase heat transfer is based on an empirical approach, where the temperature difference between the wall and bulk flow can be obtained from the heat transfer coefficient.

5. Sump pump - Wikipedia

   en.wikipedia.org/wiki/Sump_pump

   Power cord length – Running a more powerful electrical motor a long distance from the main service panel will require heavier gauge wiring to assure sufficient voltage at the motor for proper pump performance. Phase and voltage – Sump pumps powered from the AC mains are available with single-phase or three-phase induction motors, rated for ...

6. Electrohydraulic servo valve - Wikipedia

   en.wikipedia.org/wiki/Electrohydraulic_servo_valve

   A servo valve receives pressurized hydraulic fluid from a source, typically a hydraulic pump. It then transfers the fluid to a hydraulic cylinder in a closely controlled manner. Typically, the valve will move the spool proportionnaly to an electrical signal that it receives, indirectly controlling flow rate.

7. Hydraulic motor - Wikipedia

   en.wikipedia.org/wiki/Hydraulic_motor

   However, many hydraulic pumps cannot be used as hydraulic motors because they cannot be backdriven. Also, a hydraulic motor is usually designed for working pressure at both sides of the motor, whereas most hydraulic pumps rely on low pressure provided from the reservoir at the input side and would leak fluid when abused as a motor.
