Cavitation
Cavitation is characterised by parts of the pumped fluid forcefully flashing into a vapour and the resulting formation of bubbles.
This occurs if the static pressure in the fluid falls below the temperature-related vapour pressure. A forceful implosion of the bubbles occurs when the fluid stream reaches a region of higher pressure.
Cavitation can lead to premature material wear and noise emission. Cavitation should therefore be avoided as far as possible.
