In a centrifugal pump, which component is designed to move water?

Explanation:
In a centrifugal pump, the water is moved by the impeller. The impeller’s blades spin and grab water at the center, flinging it outward. This action transfers energy from the motor into the fluid, increasing its velocity and, with the pump casing, converting that velocity into pressure to push the water through the discharge line. The shaft’s job is to rotate the impeller by transmitting power from the motor; it doesn’t move water itself. A valve controls flow, not the actual pumping action, and a cylinder isn’t the component that drives the movement in this type of pump.
