Pump packing boxes, bearings and casing shall be checked for __________.

Pump packing boxes, bearings and casing shall be checked for __________.

• A. Leaks
• B. Overheating
• C. Corrosion
• D. Wear

Answer: (B)

Excess heat in those components is the clearest sign that something is not right during operation. If packing, bearings, or the casing get too hot, it points to lubrication problems, excessive friction from misalignment, worn bearings, or packing that isn’t moving freely. That overheating can quickly lead to seal damage, bearing failure, or a pump seizure if the test continues, so it’s the most reliable indicator to stop and inspect. Leaks, corrosion, or wear can be present for other reasons or develop over time, but they don’t signal an immediate abnormal operation the way overheating does.
