The usual symptoms of cavitation in a centrifugal pump is __________.

Question 1 of 27070

The usual symptoms of cavitation in a centrifugal pump is __________.

🔍 Key Concepts

• Cavitation in a centrifugal pump and how vapor bubbles form and collapse • What happens to noise, vibration, and performance when a pump is starved of suction head • Difference between pressure changes and mechanical symptoms (sound/feel)

💭 Think About

• When vapor bubbles form and collapse in a pump, what would you expect to hear and feel in the casing and piping? • If the pump is experiencing cavitation, does it normally cause pressures (suction or discharge) to increase, or does it damage/strain the internals? • Which choice sounds like a direct physical effect at the pump, and which sound more like system pressure responses?

✅ Before You Answer

• Match the symptom directly to the physical effect of bubbles collapsing on the impeller • Eliminate any option that suggests higher pressures as a normal result of cavitation • Focus on the choice that best describes audible and tactile warning signs at the pump itself
