2. Submersible pump - Wikipedia

   en.wikipedia.org/wiki/Submersible_pump

   A submersible pump (or electric submersible pump ( ESP) is a device which has a hermetically sealed motor close-coupled to the pump body. The whole assembly is submerged in the fluid to be pumped. The main advantage of this type of pump is that it prevents pump cavitation, a problem associated with a high elevation difference between the pump ...

3. Pumpjack - Wikipedia

   en.wikipedia.org/wiki/Pumpjack

   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. The arrangement is often used for onshore wells. Pumpjacks are common in oil-rich areas .

4. Oil pump - Wikipedia

   en.wikipedia.org/wiki/Oil_pump

   Oil pump may refer to: Hydraulic pump, which pressurizes hydraulic fluid in a hydraulic system. Oil pump (internal combustion engine), a part of the lubrication system that pressurizes motor oil for distribution around the engine. Pumpjack, often used to pump oil out of wells. Submersible pump, often used to pump oil out of wells. Vacuum pump ...

5. Extraction of petroleum - Wikipedia

   en.wikipedia.org/wiki/Extraction_of_petroleum

   Petroleum is mostly recovered from oil drilling. Seismic surveys and other methods are used to locate oil reservoirs. Oil rigs and oil platforms are used to drill long holes into the earth to create an oil well and extract petroleum. After extraction, oil is refined to make gasoline and other products such as tires and refrigerators.

6. Centrifugal pump - Wikipedia

   en.wikipedia.org/wiki/Centrifugal_pump

   Centrifugal pumps are used to transport fluids by the conversion of rotational kinetic energy to the hydrodynamic energy of the fluid flow. The rotational energy typically comes from an engine or electric motor. They are a sub-class of dynamic axisymmetric work-absorbing turbomachinery. [1]

7. Rotary vane pump - Wikipedia

   en.wikipedia.org/wiki/Rotary_vane_pump

   4. spring. A rotary vane pump is a type of positive-displacement pump that consists of vanes mounted to a rotor that rotates inside a cavity. In some cases these vanes can have variable length and/or be tensioned to maintain contact with the walls as the pump rotates. This type of pump is considered less suitable than other vacuum pumps for ...
