| Check Item | Target Range | Red Flag / Action | | :--- | :--- | :--- | | | Typically < 140°F - 160°F (Check OEM specs). | If housing is too hot to touch (>140°F), check lubrication levels immediately. | | Motor Temperature | Compare to ambient + rated temp rise. | Overheating indicates electrical faults or overloading. | | Seal Temperature | Should not exceed process fluid temp significantly. | Overheating seal faces indicate dry running or flush plan failure. | | Oil Analysis | Check for discoloration (milky = water, black = carbon). | Hot oil oxidizes faster; change oil if temp spikes persist. | | Cooling Water Lines | Ensure flow is unobstructed. | If the pump has a cooling jacket, a blockage causes rapid overheating. |
Isolate all electrical power sources to the pump motor at the breaker panel.
Use Data Validation for "Status" columns (e.g., Pending, Completed, Deferred).
