Common failures & inspection points
Measure wear ring clearance with feeler gauge or dial indicator; clearance exceeding manufacturer specification indicates recirculation, efficiency loss, and potential failure
Inspect mechanical seal surfaces (SIC/Carbon faces) for scoring, pitting, or wear under magnification; check for weeping/dripping from seal drain; verify seal assembly torque and condition of springs
Verify cooling water passages are clear of salt deposits, corrosion products, or biological growth; check differential pressure across coolers/jackets/heat exchangers; use cooling water flow test
Check axial and radial alignment with dial indicator per manufacturer tolerance (typically <0.05mm); inspect coupling for wear, cracking, or deformation; verify coupling bolts are properly torqued
Monitor bearing temperature with infrared thermometer (should not exceed 60-65°C under normal operation); listen for grinding/grinding noises; feel for play in bearing housing; check bearing oil for water ingress and discoloration
