What is the main consequence of cavitation in a pump?

Cavitation occurs when the pressure in a pump falls below the vapor pressure of the fluid, leading to the formation of vapor bubbles. These bubbles can create significant problems when they collapse or implode, which typically happens as the fluid moves through the pump. One of the most significant consequences of this phenomenon is the damage to pump components.

When the vapor bubbles collapse, they generate shock waves that can erode the surfaces of impellers and other components, leading to pitting and wear. Over time, this damage not only reduces the performance of the pump but can also lead to complete failure if not addressed. The physical integrity of the pump is compromised, which necessitates repairs or complete replacement of the affected parts. Thus, the main consequence of cavitation is indeed the damage it causes to the pump’s components.
