Pump Preventive Maintenance Checklist Excel Hot -

Before diving into the specific checks, it is vital to understand why Excel is the preferred medium for preventive maintenance (PM):

| 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 | pump preventive maintenance checklist excel hot
