Radial flow design is a _____ pump.

Radial flow design is a _____ pump.

• A. Axial pump
• B. Centrifugal pump
• C. Jet pump
• D. Mixed-flow pump

Answer: (B)

Radial flow design describes a pump where the fluid enters near the center and exits outward toward the periphery, gaining energy as it moves outward through the impeller. This outward, radial movement is the hallmark of centrifugal pumping action, so a radial-flow pump is a centrifugal pump. Axial pumps move fluid mainly along the axis of rotation (like a propeller), jet pumps use a jet to entrain fluid rather than rely on a radial impeller, and mixed-flow pumps combine axial and radial flow. Understanding this helps you identify the pump type by how the liquid actually flows inside the impeller.
