Can centrifugal pumps be damaged by running dry?

Centrifugal pumps can indeed be damaged by running dry, leading to various issues such as overheating and mechanical failure. When a centrifugal pump operates without sufficient fluid to transport, it can generate excessive heat due to friction among the internal components. This heat can degrade the materials, damage seals, and ultimately lead to pump failure.

It's essential to recognize that most centrifugal pumps depend on the fluid for lubrication and cooling. Without liquid, the mechanical components may experience wear and failure because there is no medium to absorb the resulting heat from the pump's operation.

Understanding the specifics of pump design is crucial. Some pumps may include protections against running dry, but in general, the risk of damage is present if a centrifugal pump operates without being adequately primed or if it runs out of liquid due to suction issues or leaks.
