What does a volute centrifugal pump's operation involve?

• A. Water enters at the discharge and flows inward
• B. An impeller rotates in a vacuum environment
• C. Water enters at the eye of the impeller and is thrown outward
• D. The pump uses a check valve for operation

Answer: (C)

In a volute centrifugal pump, the operation is characterized by the way water enters the pump and how it is manipulated by the impeller. Water flows into the pump at the eye, or center, of the impeller. As the impeller rotates, it imparts kinetic energy to the water, causing it to be thrown outward towards the pump's discharge. This flow pattern is fundamental to the pump's effectiveness, as the design maximizes energy transfer and increases the pressure of the liquid being pumped. The use of the impeller in this manner is crucial; it allows the pump to efficiently convert mechanical energy into hydraulic energy. The volute casing that encases the impeller serves to convert this high-velocity water flow from the impeller into a higher pressure as it moves to the discharge point. Understanding this operation is key to grasping how volute centrifugal pumps function and why they are widely used in various applications that require managing the flow of liquids.
