The main purpose of a centrifugal pump is to:

• A. Move a small volume of fluid with high pressure
• B. Mix solid and liquid components
• C. Move a lot of fluid without adding too much pressure
• D. Compress gases for high pressure delivery

Answer: (C)

A centrifugal pump is specifically designed to transport large volumes of fluid efficiently. It operates using rotational energy, provided by a rotating impeller, which creates a high flow rate. The centrifugal force generated by the impeller blades pushes the fluid outward, effectively moving it from the inlet to the outlet. The primary function of this type of pump is to achieve high flow rates rather than high pressure. While it does produce some pressure as the fluid is moved, the main advantage of a centrifugal pump is its ability to handle large volumes of liquid at relatively low pressures, making it an ideal choice for various applications in wastewater treatment, water supply, and irrigation systems. In contrast, the other options pertain to different functionalities not suited for centrifugal pumps. For instance, moving a small volume of fluid with high pressure is more characteristic of positive displacement pumps, which are designed to ensure a specific amount of fluid is moved at high pressure. Mixing solid and liquid components is typically the role of a mixer or a specific type of agitator, while compressing gases for high-pressure delivery is usually associated with compressors, not pumps designed for liquid transport.
