Prevents catastrophic failures or pressurized leaks of hazardous fluids.
Highlight risks automatically. Set up a conditional formatting rule that turns a row light red if the Status is "Fail," or if a recorded temperature exceeds a safe threshold (e.g., >180°F for standard bearings).
Vibration was 0.12 IPS last week (Cell C2). This week it is 0.18 IPS (Cell C3). =((C3-C2)/C2)*100 Result: 50% increase. If ROC > 30%, the checklist should flag a "Predictive Alarm."
Monthly tasks involve hands-on assessments, system cleaning, and physical verification of mechanical structural integrity. 1. Vibration Analysis (Baseline Tracking)
Use Data Validation (Data > Data Validation > List) for the "OK/Fail" column so operators just click a dropdown (Yes/No). Add a column for "Notes" to log unusual noises (e.g., "Loud rattling after 2 hours of hot run"). pump preventive maintenance checklist excel hot
Set aside time each month for these deeper checks. Record the findings in your Excel file. Wipe dust and grime off the motor. Check belts: Look for cracks or slips on belts. Test seals: Make sure the packing seals grip right. View mounts: Check that bolts hold the pump tight. Quarterly and Annual Deep Maintenance
For oil-lubricated bearings, check the bullseye sight glass. The oil should be clear and amber. Milky oil indicates water contamination (often from a leaking seal or condensation); black oil indicates extreme thermal breakdown.
Regular lubrication and alignment reduce bearing wear and seal failure.
Record gauge readings. Cross-reference these with the pump's performance curve to ensure the pump is operating within its Best Efficiency Point (BEP) and not running at shut-off or far-out on the curve. Vibration was 0

Daily checks are visual and auditory inspections designed to catch anomalies before they escalate into system failures. These should be performed during standard operator rounds. 1. Visual Leak Inspections
Excel remains one of the most effective tools for tracking pump preventive maintenance. It is flexible, auditable, and accessible across teams. A well-designed Excel checklist helps you:
A systematic approach to pump maintenance, documented through an Excel checklist, is essential for industrial safety and reliability. By conducting regular, structured checks, you can significantly reduce the risk of failure in hot service pumps. If ROC > 30%, the checklist should flag
Add in Excel:
| | Task | Why It's Important (The "Hot" Perspective) | | :--- | :--- | :--- | | Visual Inspection | Check for leaks around the pump body, seals, gaskets, and pipe joints. | Leaks can lead to loss of hazardous fluids and air ingress, which can cause overheating and cavitation. | | Performance Monitoring | Record suction/discharge pressure readings and monitor motor current (amps). | Comparing real-time data against the pump's performance curve helps detect inefficiencies that generate excess heat. | | Temperature Check | Use an infrared thermometer to measure bearing housing temperature. Look for a sustained rise above baseline. | A sudden or gradual increase in bearing temperature is a primary indicator of lubrication failure, misalignment, or bearing wear. | | Vibration & Noise | Listen for unusual noises like grinding, humming, or cavitation (sounds like gravel). Check for abnormal vibration. | Unusual noise often signals cavitation—the formation and collapse of vapor bubbles—which causes intense localized heating and severe impeller damage. | | Lubrication | Visually inspect oil levels in bearing housings. Check for water or discoloration in the oil. | Lubrication is crucial for heat management; contaminated or low oil levels will cause bearing temperatures to spike rapidly. |
This is a comprehensive inspection that often involves full or partial pump disassembly and is best planned as part of a scheduled plant shutdown.
