What does the shaft in a centrifugal pump connect?

• A. The impeller to the casing
• B. The pump to the motor
• C. The stuffing box to the impeller
• D. The packing material to the casing

Answer: (B)

In a centrifugal pump, the main function of the shaft is to connect the pump to the motor. The shaft transmits the rotational energy from the motor to the impeller, which is located inside the pump casing. This connection allows the motor's drive to create the motion necessary to draw water into the pump and subsequently discharge it at a higher velocity. This connection is essential for the operational dynamics of the pump, as it facilitates the conversion of mechanical energy into hydraulic energy, which is the core purpose of a centrifugal pump. By linking the motor to the pump, the shaft enables the impeller to spin and generate flow, making it a critical component in the overall functioning of the pump system.
