Even a "hot" checklist can fail. Avoid these errors:
A pump does not fail suddenly. It fails slowly—first a 0.01 in/sec vibration increase, then a 4°F temperature rise, then a dripping seal. Only a structured, "hot" Excel checklist captures these subtle changes before they become catastrophic.
Printing a paper checklist and carrying a clipboard is industrial archaeology. Using a dynamic, conditional-formatting-driven, trend-calculating Excel workbook turns your maintenance team into predictive analysts.
Implement this checklist tomorrow. Track your data for 90 days. Then, count how many emergency Saturday callouts you avoided.

| Frequency | Component | Action Item | Acceptable Criteria | Hot-Service Note | |-----------|-----------|-------------|----------------------|-------------------| | Daily | Bearing housing | Check temp (thermometer or IR gun) | <180°F (82°C) for oil; <200°F for grease | Log trend; sudden rise = failure warning | | Daily | Mechanical seal | Check for leakage | <5 drops/min from drain port | More leakage = seal faces warped from heat | | Daily | Casing | Listen for cavitation/rumbling | Smooth sound | High temp reduces NPSH – check suction pressure | | Weekly | Lubrication | Check oil level & color | Clear, no milky/black | Hot pumps need synthetic oil if >200°F | | Weekly | Coupling alignment | Thermal alignment check (when hot) | Within 0.002" parallel, 0.001" angular | Align at operating temp, not cold | | Monthly | Jacketed stuffing box | Verify cooling flow | Flow visible in sight glass or temp <150°F | Critical for hot pumps | | Monthly | Vibration | Measure at DE & NDE | <0.2 in/s RMS (ISO 10816-3) | Increase frequency if hot service | | Quarterly | Flush piping | Check for coking / scale | No blockage in flush line | Common in hot oil pumps | | Annually | Internal clearances | Measure wear rings | Within pump manual spec | Heat accelerates wear | Even a "hot" checklist can fail
You don't need to start from scratch. Here is a raw table you can copy/paste into Excel right now:
| Date | Time | Pump ID | Hot Status (Y/N) | Suction (psi) | Discharge (psi) | Diff Press | Motor Amps | Casing Temp (°F) | Vibration | Action Required | | :--- | :--- | :--- | :--- | :--- | :--- | :--- | :--- | :--- | :--- | :--- | | 4/19/2026 | 08:00 | P-101 | Y | 22 | 110 | 88 | 48 | 165 | Smooth | OK | | 4/19/2026 | 14:00 | P-101 | Y | 21 | 95 | 74 | 52 | 210 | Rough | Check Impeller |
Pro Tip: Use Excel's Conditional Formatting (Home Tab > Styles).
| Pump ID | Drive Coupling Alignment (Mil deviation) | Baseplate Bolt Torque (ft-lbs) | Breather Vent Condition | Gland Packing Adjustment | Motor Cooling Fan Clean | Health Score (Calculated) |
| :--- | :--- | :--- | :--- | :--- | :--- | :--- |
| P-101 | 2 mils | 150 ft-lbs | Clean | 2 drips/min | Yes | 92% |

Excel Formula for Cell E2:
=IF(D2>50,"CRITICAL HOT",IF(D2>25,"WARNING","NORMAL"))
Why this is hot: You can instantly see which pumps are running outside their thermal envelope. Use Excel’s Conditional Formatting (Home > Conditional Formatting > Color Scales) to turn cells red when Delta T exceeds 40°F.
Most maintenance checklists focus on Lockout/Tagout (LOTO) status. While safety is paramount, 80% of pump failures show symptoms before the pump stops. A "Hot" checklist allows you to catch:
Warning: Only trained personnel using proper safety gear (gloves, safety glasses, hearing protection) should perform hot checks on rotating equipment.
