How does an impeller function in a pump?

• A. It sucks fluid in
• B. It throws the fluid
• C. It holds the fluid
• D. It compresses the fluid

Answer: (B)

An impeller functions in a pump by throwing the fluid, which is accomplished through its design and motion. As the impeller rotates, it generates centrifugal force that pushes the fluid outward from the center of the impeller. This action increases the kinetic energy of the fluid, propelling it toward the discharge outlet of the pump. This mechanism is essential in various types of pumps, especially centrifugal pumps, where the movement and acceleration of the fluid are critical for efficient operation. The design of the impeller, including the shape and number of blades, influences how effectively it can move the fluid. By throwing fluid efficiently, the impeller helps maintain a continuous flow, ensuring that the system operates effectively and meets the desired hydraulic performance.
