What is the consequence of cavitation in pumps?

Cavitation in pumps occurs when the pressure of the liquid falls below its vapor pressure, leading to the formation of vapor bubbles within the fluid. These vapor bubbles can then collapse violently when they move into areas of higher pressure, creating shock waves that can cause significant damage to the pump components, such as impellers and casings. This damage not only reduces the pump's efficiency but can also lead to costly repairs and downtime.

In addition to the physical impacts, the presence of cavitation results in a reduced flow rate and overall degraded performance of the pump. This condition also tends to create noise and vibration, further signaling a decline in the operational efficiency of the system. Thus, the consequences of cavitation are serious and can compromise the reliability and longevity of the equipment.
