Which part of a centrifugal pump is responsible for supplying energy to the fluid?

• A. Diffuser.
• B. Casing.
• C. Impeller.
• D. Seal.

Answer: (C)

The impeller is the component of a centrifugal pump that is crucial for supplying energy to the fluid. It consists of blades or vanes that rotate at a high speed, drawing the fluid into the pump and imparting kinetic energy to it. This kinetic energy is then converted into pressure energy as the fluid exits through the pump discharge. The design of the impeller allows it to increase the velocity of the fluid significantly, which is essential for creating the necessary flow and pressure in the system. The effectiveness of the impeller directly influences the pump's performance, including its capacity and efficiency in moving fluids. Other components, such as the diffuser, casing, and seals, play important roles in the overall pump operation but do not directly supply energy to the fluid. The diffuser helps in converting the kinetic energy from the fluid into pressure and directing the flow efficiently, while the casing houses the impeller and creates a controlled environment for fluid movement. Seals are critical for preventing leakage and maintaining pressure but are not involved in energy transfer. Therefore, the impeller's design and function are central to a centrifugal pump's ability to work effectively.
