What is the term for the disruption in pump operation when it runs dry?

The term used to describe the disruption in pump operation when it runs dry is pump cavitation. This phenomenon occurs when the pressure drops below the vapor pressure of the liquid being pumped, leading to the formation of vapor bubbles in the liquid. When these vapor bubbles collapse or implode as they move into areas of higher pressure within the pump, it can cause significant damage to the pump components and reduce its efficiency.

Understanding pump cavitation is crucial for maintaining proper pump operation and longevity. It emphasizes the importance of ensuring that the pump always has adequate fluid supply and pressure to prevent livestock damage and operational failures. Knowledge of this term is vital for firefighters and other professionals who deal with pumps in high-pressure situations, ensuring they can take appropriate measures to prevent cavitation and maintain effective pumping operations.
