What outcome arises when centrifugal pumps experience insufficient net positive suction head (NPSH) in HVAC chilled water systems?

💡 Explanation

Insufficient NPSH results in cavitation because localized pressure drops below the fluid's vapor pressure, creating vapor bubbles that collapse and damage the pump. Therefore, efficiency drops with diminished cooling, rather than better efficiency or stable operation.
