Centrifugal Pump Basics - How centrifugal pumps work working principle hvacr

The video tutorial explains the components and operation of centrifugal pumps, focusing on the motor, shaft, and impeller. It covers the mechanics of three-phase induction motors, the role of the pump casing, and the dynamics of fluid movement. The tutorial also introduces the concept of Net Positive Suction Head (NPSH) and the phenomenon of cavitation, emphasizing the importance of maintaining proper pressure levels to prevent damage. Finally, it highlights the diverse applications of centrifugal pumps in various systems.
