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.

Pump Selection

Centrifugal pumps should be selected such that the specified System Duty Point is located on or as near as possible to the point of maximum efficiency (Pump Duty Point) of the max. speed H/Q-curve.
