🔍 Key Concepts

• Flow direction in centrifugal pumps – how liquid normally moves from eye to discharge when the impeller turns correctly • Impeller vane shape and curvature – what happens if you try to push liquid the "wrong" way across the vanes • Difference between flow direction and shaft power / efficiency / head when rotation is reversed

💭 Think About

• Think about the geometry of a double‑suction impeller: how is it designed to take in liquid and how would that change if the impeller is spun the other way? • If you reverse rotation, will the pump suddenly become better at producing head, or will performance (head/efficiency/power) get worse? Why? • Consider whether reversing rotation can make the pump push liquid back out of the original suction nozzle, or whether internal recirculation and loss of efficiency are more likely.

✅ Before You Answer

• Verify where suction and discharge nozzles are located in a centrifugal pump and whether they change just because rotation is reversed • Check how vane curvature affects head and efficiency when rotation is correct vs. incorrect • Consider whether power demand tends to increase or decrease when a centrifugal pump is run in the wrong direction (look for effects like recirculation, turbulence, and low efficiency).
