2. Oil pump (internal combustion engine) - Wikipedia

   [c] These are supplementary pumps and do not replace the main, mechanical, oil pump. Electric pump as a main engine pump again will require big electric motors and it may be simply cheaper to drive directly from the engine. For e.g. BMW S65 engine's oil pump delivers ca. 45 LPM (Litres Per Minute) of oil at 5.5 bar pressure. [5]

   EDC pump actuator. Electro-magnetic actuators are usually located on the fuel pump to transfer electrical signals into mechanical action in this case fuel rack actuator and or fuel stop solenoid which means that depending on requests from control unit full fuel or no fuel quantity. Injectors; Boost-pressure actuator; Intake-duct switchoff

4. 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.

5. Power transmission - Wikipedia

   en.wikipedia.org/wiki/Power_transmission

   This technology survived into the 21st century in a handful of oilfields in the US, transmitting power from a central pumping engine to the numerous pump-jacks in the oil field. [ 3 ] Mechanical power may be transmitted directly using a solid structure such as a driveshaft ; transmission gears can adjust the amount of torque or force vs. speed ...

6. Pumpjack - Wikipedia

   en.wikipedia.org/wiki/Pumpjack

   Pump size is also determined by the depth and weight of the oil to remove, with deeper extraction requiring more power to move the increased weight of the discharge column (discharge head). A beam-type pumpjack converts the rotary motion of the motor (usually an electric motor ) to the vertical reciprocating motion necessary to drive the ...

7. Hydraulic machinery - Wikipedia

   Disadvantages: The pump cannot be utilized for any other hydraulic function in an easy way and cooling can be a problem due to limited exchange of oil flow. High power closed loop systems generally must have a 'flush-valve' assembled in the circuit in order to exchange much more flow than the basic leakage flow from the pump and the motor, for ...
