🔍 Key Concepts

• Pump shaft sleeve function and why scoring (grooving or scratching) is a problem • Difference between correcting symptoms (e.g., speed, leakage) vs. correcting the root cause of wear • Standard maintenance practice when damage is found on a replaceable part like a sleeve

💭 Think About

• Ask yourself: Does this choice fix only how the pump operates, or does it actually address the mechanical damage you just found? • Is the sleeve designed to be adjusted, aligned, or replaced when damaged? • Which option prevents the scoring from quickly getting worse and possibly damaging the shaft or packing?.

✅ Before You Answer

• Verify which choices actually remove or repair the damaged sleeve vs. just changing operating conditions. • Check whether the option deals with the cause of scoring (e.g., grit, misalignment, dry running) instead of ignoring it. • Confirm that standard practice for a scored, replaceable wear part is to correct the cause and renew the part, not to keep running it.
