Question

Multi-stage centrifugal pumps are used to:

• A. give high discharge
• B. produce high heads
• C. pump viscous fluids
• D. all of these

Answer 1

Answer:

B. produce high heads

Multistage centrifugal pumps are used to produce high heads by connecting multiple liquid chambers (or stages) in series. The more stages the pump has, the higher the final discharge pressure, but the flow range always remains constant for a given rpm.
