Discharge Cavitation - Centrifugal Pump

Discharge Cavitation. Discharge cavitation occurs when the pump discharge pressure is extremely high or when the discharge flow is restricted and cannot leave the pump (e.g. caused by closed outlet valve). An extremely high discharge pressure results in the majority of the pumped fluid circulating inside the pump.. This type of cavitation originates from two sources.
