A centrifugal pump is called a turbine pump, if it is having a_________________?
Correct answer: D. Vaned diffusion casing
- A. Turbine type impeller
- B. None of these
- C. Rotating vaned volute
- D. Vaned diffusion casing
Explanation
A centrifugal pump is termed a turbine pump when it uses a diffuser or vaned diffusion casing to convert part of the impeller's velocity head into pressure head. A volute casing is a different pump-casing arrangement.
