Which risk increases when a pump impeller's rotation achieves high frequency?

💡 Explanation

Increased impeller frequency causes turbulence, leading to local pressure drops. Vapor bubbles form, and their subsequent collapse causes cavitation erosion because the implosion's force damages the impeller, therefore increased blade erosion rather than the listed alternatives.
