What is cavitation?

Cavitation is the formation and subsequent implosion of vapor bubbles within the liquid. It occurs when the pressure inside the circuit equals or drops below the liquid value tension. It is accompanied by the characteristic noise produced by the strong impacts of the steam bubbles that implode against the solid surfaces of the pump. Cavitation reduces the hydraulic performances of the pump, generates surface erosion and vibrations that mechanically damage the pump.
