What is a common cause of pump failure?

Cavitation is a phenomenon that often leads to pump failure, making it a common concern in pump operations. It occurs when the pressure in the pump drops below the vapor pressure of the liquid being pumped, resulting in the formation of vapor bubbles. These bubbles can collapse violently, causing shock waves that can damage the internal surfaces of the pump. This damage might include pitting of the impeller or other components, which can severely affect the pump's performance and lifespan.

Understanding cavitation helps operators to recognize conditions that may lead to its occurrence, such as excessive flow rates, high temperatures, or inadequate suction supply. By addressing these factors, the risk of cavitation and subsequent pump failure can be significantly reduced.
