While starting an axial flow pump, its delivery valve should be kept _______________?
Correct answer: A. Open
- A. Open
- B. Closed
- C. Either open or closed
- D. None of these
Explanation
An axial-flow pump should be started with its delivery valve open because it develops high flow and relatively low head, so throttling the discharge can overload the pump. This differs from many centrifugal pumps, which are commonly started against a closed valve.
