🔍 Key Concepts

• Centrifugal pump operating symptoms such as vibration, noise, loss of efficiency • Mechanical vs. hydraulic faults (alignment, shaft condition, wrong rotation, internal wear) • Effect of shaft alignment and rotation direction on pump behavior

💭 Think About

• Which of these faults would most directly create unbalance or misalignment that is felt as vibration at all speeds? • Which conditions tend to show up more as loss of capacity/pressure rather than obvious noise and vibration? • How would a pump behave if it were turning in the wrong direction versus if its internal clearances were simply worn?

✅ Before You Answer

• Match the symptom: vibration + noise together, not just leakage or reduced flow • Consider which choice would most affect rotating balance and alignment of the impeller and shaft • Think about what a reversed direction of rotation typically changes: flow/pressure vs. mechanical balance
