Common failures & inspection points
Inspect mechanical shaft seals for weeping or spray pattern; verify seal type matches media (standard vs. special for high temperature); check coupling condition and vibration levels
Visual inspection of impeller blade surface for pitting, erosion, or material loss; measure impeller diameter wear and compare against design tolerance; assess suction-side NPSH adequacy
Monitor bearing temperature (infrared or contact), check lubricant level and condition (contamination, discoloration), listen for abnormal noise; verify bearing pre-load is correct
Check for galvanic corrosion between dissimilar metals; inspect stainless steel components for pitting or stress-corrosion cracking; verify seawater pump materials (bronze, duplex) are properly selected
Verify inlet suction strainer is clear of debris; check differential pressure across strainer; inspect foot valve (if present) for sticking; confirm priming capability of self-priming pumps
