Which risk increases when a centrifugal pump impeller's inlet pressure drops?

💡 Explanation

Cavitation risk increases because reduced pressure leads to the fluid flashing into vapor bubbles; implOSION of these bubbles erodes the impeller metal through micro-jetting. Therefore pump performance rapidly degrades, rather than improving, and seal/lubricity remain unaffected.
