🔍 Key Concepts

• Centrifugal pump performance and how head pressure should respond when the discharge valve is throttled or closed • Typical symptoms of pump wear (impeller wear, internal clearances, casing erosion) versus symptoms of drive motor or coupling problems • Difference between problems that require pump overhaul vs. problems that indicate external/ancillary equipment issues

💭 Think About

• Which option directly reflects a loss of hydraulic performance inside the pump, rather than an issue with the motor, coupling, or speed control? • In a healthy centrifugal pump, what should happen to discharge pressure (head) when you slowly close the discharge valve at constant speed? • Which of the listed symptoms would be the most specific and measurable indication that internal wear or damage has reduced the pump’s ability to build head?

✅ Before You Answer

• Verify which symptom is a hydraulic performance issue (pressure/head) rather than a mechanical noise/vibration symptom only • Check which condition would still occur even if the motor and coupling are in perfect condition • Confirm which option indicates the pump can no longer develop additional head when flow is restricted (a classic sign of worn internals requiring overhaul)
