Which of the following is used for pumping crude oil from oil well ?
Correct answer: B. Duplex/triplex reciprocating pump
- A. Single stage centrifugal pump
- B. Duplex/triplex reciprocating pump
- C. Screw pump
- D. Gear pump
Explanation
Duplex or triplex reciprocating pumps are positive-displacement pumps capable of delivering crude oil from wells against substantial pressure. Their reciprocating action provides the high-pressure pumping needed in such service.
