Which effect results when differential vapor pressure in a centrifugal refrigerant pump exceeds design limits?

💡 Explanation

Cavitation occurs because the decreasing pressure causes refrigerant flashing into vapor preventing effective pumping; the vapor bubble collapse causes pitting. Therefore cavitation erodes pumps, rather than benefiting from temperature reduction or raising downstream pressure.
