Which outcome occurs when a centrifugal pump loses prime in a refrigeration system?

💡 Explanation

Losing prime introduces air, causing vapor lock because it disrupts liquid flow within the pump, triggering cavitation as vapor bubbles collapse against the impeller. Therefore, cavitation damage occurs rather than increased efficiency, whose outcomes exist under proper priming with complete fluid fill.
