Priming is needed in a ______________ pump?
Correct answer: C. Centrifugal
- A. Reciprocating
- B. Gear
- C. Centrifugal
- D. Diaphragm
Explanation
A centrifugal pump must first have its casing and suction line filled with liquid because it cannot effectively create suction while filled with air. This filling operation is called priming.
