Common failures & inspection points
Verify pump casing material is bronze, aluminum bronze, copper bronze, or stainless steel (NOT cast iron for bilge/seawater service). Check surface for pitting, graphite skeleton formation, or soft areas indicating corrosion.
Inspect all shaft seals, fasteners, and connections for tightness and any signs of fluid weeping. Check packing gland condition and seal wear. Verify no active leaks from pump body or discharge points.
If accessible, inspect impeller for erosion damage, cavitation pitting, or debris accumulation. Check for wear patterns indicating improper clearances. Verify smooth operation during performance testing.
For pumps with visible bearing arrangements (CNLB, DHB series), inspect bearing housing for leakage or contamination. Verify adequate lubrication and absence of noise/vibration during operation.
Verify current classification society documentation (ABS, DNV, BV, LR, or equivalent). Confirm certificate matches pump model designation and is not expired. For replacement pumps, ensure equivalent certification is maintained.
