What is a common pump type used in water treatment plants?

• A. Diaphragm pump
• B. Centrifugal
• C. Positive displacement
• D. Gear pump

Answer: (B)

Moving large volumes of water efficiently is essential in water treatment plants. Centrifugal pumps work by spinning an impeller inside a housing to fling water outward, converting the speed of the impeller into flow. This design provides a steady, high-capacity flow that can be adjusted to demand by changing the pump speed or using multiple stages for higher heads. They’re simple, durable, and cost-effective for conveying raw and treated water through processes like filtration, mixing, and distribution. While other pumps have specialized uses—diaphragm pumps for slurries or precise dosing, gear and other positive-displacement pumps for high-pressure or metered flows—the centrifugal pump is the common workhorse for general water movement.
