Common failures & inspection points
Inspect mechanical seal faces for wear, damage, and verify no leakage from seal interface to atmosphere
Check double ball bearing condition including grease level, signs of corrosion, and abnormal noise during operation
Inspect impeller (flexible rubber or rigid) for erosion, cavitation pitting, notches, rust, scaling, and bent vanes - replace if wear exceeds 1/8 inch deep
Verify wear ring clearances and shaft runout to ensure proper alignment and prevent recirculation loss and efficiency degradation
Monitor bearing housing temperature with thermal gun during operation - abnormal elevation indicates bearing issues
Check coupling alignment and shaft integrity for proper transmission of rotational forces
Inspect pump body for corrosion, crack propagation, and material degradation (especially important for marine saltwater service)
Verify all fasteners, bolts, and connection ports for tightness and condition - address any seepage at gaskets
