To produce a high head multi stage centrifugal pumps the impellers are connected

MPSC 2015 Paper-II Mains

⭕ (a) in parallel

⭕ (b) in series

⭕ (c) in parallel and in series both

⭕ (d) None of the above

Explanation: In multi-stage centrifugal pumps, impellers are connected in series to increase the head of the pump. If higher discharge is required, impellers are placed in parallel.

Parts of a Centrifugal Pump:

• 1. Impeller
• 2. Casing
• 3. Suction pipe with foot valve and strainer
• 4. Delivery pipe

Connection of Impellers in Multi-Stage Centrifugal Pumps

This MCQ focuses on how impellers are arranged to achieve high head in multi-stage centrifugal pumps, which is a key topic in fluid mechanics and pump engineering.

Key Concepts:

• Series connection → Increases head
• Parallel connection → Increases discharge

Conclusion:

The correct answer is in series. This concept is vital in understanding centrifugal pump design for applications requiring high heads and appears frequently in technical exams like MPSC, SSC-JE, and GATE.
