Common failures & inspection points
Confirm 304 vs 316/316L material for seawater applications (316L required for marine use per ASME/ISO); examine nameplate and casing stampings
Visual inspection for erosion/corrosion damage, cavitation pitting, impeller balance verification; measure with calipers against design drawings
Check seal orientation (SiC/Carbon/EPDM standard); verify proper cooling/flushing for freshwater vs seawater; monitor leakage rate (<1 drop/min acceptable)
Check axial/radial play (shall-not-exceed limits per ISO 1101); ultrasonic vibration signature analysis; oil condition testing for bearing health
Verify pump rated pressure matches system requirements (typically 10-16 bar for Ebara cooling); confirm temperature rating matches liquid (±120°C max standard)
