Which risk increases when a centrifugal pump supplying chilled water to a data center runs at very low speed?

💡 Explanation

Centrifugal pumps operating far from their Best Efficiency Point experience recirculation at the impeller inlet; this causes the local pressure to drop which leads to vapor bubble formation (cavitation). The collapse of those bubbles generates pitting damage to the impeller itself, rather than other modes because pressure is the dominant variable.
