Pump Cavitation Explained Simply. Pump cavitation is one of the most common causes of pump failure in industrial systems. It happens when low pressure creates vapor bubbles that collapse violently, damaging the pump impeller and reducing efficiency. In this video, we explain cavitation in pumps in a simple way, including causes like low suction pressure, poor system design, and incorrect operation. Learn how cavitation leads to noise, vibration, and equipment damage, and how to prevent it in cen
