What are the two main parts of a centrifugal pump?

The two main parts of a centrifugal pump are the impeller and the casing. The impeller is a rotating component that converts mechanical energy from the pump's motor into kinetic energy in the fluid being pumped. As the impeller spins, it creates a pressure differential that draws fluid into the pump and forces it out through the casing.

The casing, on the other hand, is the stationary part that surrounds the impeller. It serves multiple functions: it directs the flow of fluid coming from the impeller and helps convert the kinetic energy generated by the impeller into pressure, allowing the fluid to be effectively moved through the discharge pipe. The design of the casing is crucial for optimizing the performance of the pump, including factors such as flow rate and efficiency.

Understanding the roles of these components helps in comprehending how centrifugal pumps operate and their application in various pumping situations, which is essential for effective operation and maintenance in scenarios encountered by mobile pump operators.
