: These components prevent fluid leakage and contamination. Regularly inspecting them for cracks or hardening is vital.

: Inspecting gaskets and mechanical seals prevents fluid loss and protects the pump internals from contamination. preventive maintenance of pumps

| Failure Mode | Root Cause | PM Action | |--------------|------------|------------| | Cavitation | Low NPSH, clogged strainer | Clean suction strainer, check fluid level, open suction valve fully | | Dry running | Loss of prime | Install low-level or flow switch; prime before start | | Leaking seal | Misalignment, debris, dry running | Align pump, flush seal flush line, never run dry | | Vibration | Unbalance, misalignment, bent shaft | Laser align, dynamically balance impeller, check shaft runout | | Overheating | Wrong lubricant, high ambient, blocked cooling | Change lubricant type, clean cooling jackets | : These components prevent fluid leakage and contamination
