Common failures & inspection points
Visual inspection of impeller blade surfaces for pitting, erosion, material loss, or uneven wear patterns; listen for cavitation noise during operation; monitor flow rate reduction
Check for liquid dripping at seal housing, visual inspection of seal faces for scoring/wear, verify seal pressure and condition; replace if leakage exceeds acceptable limits
Monitor bearing temperature (should not exceed 80°C), listen for grinding noise or vibration, check lubrication levels in larger bearing types with lubrication points
Verify suction strainers are clean and not restricted, check NPSH margin at operating point, monitor for cavitation symptoms or reduced prime capability
Test priming capacity and time to full prime, inspect check valve operation and seal integrity, verify diffuser passages are not blocked (for SA and Modular S series)
