What does "pump cavitation" typically indicate?

Pump cavitation is a phenomenon that occurs when vapor bubbles form in a liquid due to a drop in pressure. Specifically, this decrease in pressure can lead to the liquid's pressure falling below its vapor pressure, causing bubbles to form. When these bubbles move to an area of higher pressure within the pump, they collapse violently, creating shockwaves. This can result in damage to the pump components, reduced efficiency, and ultimately, pump failure.

Recognizing cavitation is critical for power engineers, as it indicates a potential issue with pump performance and can be influenced by various factors such as flow rate, pump speed, and system design. Ensuring proper operation conditions and avoiding cavitation can lead to more reliable and efficient pumping systems.
