Common failures & inspection points

Impeller/wheel inspection: check for corrosion, erosion, pitting, cracks, and blade fouling or buildup; re-balance if material loss detected

Bearing condition: inspect and re-lubricate (or replace) shaft bearings per manufacturer intervals; check for abnormal noise, vibration, or temperature rise

Shaft seal integrity: inspect neoprene or equivalent shaft seals for wear, cracking, or leakage allowing moisture ingress into bearing housing

Housing and casing integrity: inspect for corrosion, weld cracks, coating breakdown (especially inorganic zinc and epoxy layers); recoat as required per marine

Housing and casing integrity: inspect for corrosion, weld cracks, coating breakdown (especially inorganic zinc and epoxy layers); recoat as required per marine maintenance schedule

Motor inspection: verify insulation resistance (megger test), check terminal box for moisture ingress, confirm motor rating and cooling are suitable for ambient

Motor inspection: verify insulation resistance (megger test), check terminal box for moisture ingress, confirm motor rating and cooling are suitable for ambient below-deck temperature (≤50°C)

Drive components: for belt-driven units, inspect V-belt tension, wear, and alignment; check sheave grooves and tighten set-screws; for direct-drive units, verif

Drive components: for belt-driven units, inspect V-belt tension, wear, and alignment; check sheave grooves and tighten set-screws; for direct-drive units, verify coupling alignment and fastener torque

Inlet/discharge ductwork connections: inspect flexible connections, gaskets, and flanges for air leaks, corrosion, or mechanical damage; confirm no obstructions

Inlet/discharge ductwork connections: inspect flexible connections, gaskets, and flanges for air leaks, corrosion, or mechanical damage; confirm no obstructions in air path

Vibration and noise monitoring: measure and record vibration levels (compare against AMCA/ISO baseline); investigate any increase in broadband noise or tonal co

Vibration and noise monitoring: measure and record vibration levels (compare against AMCA/ISO baseline); investigate any increase in broadband noise or tonal components as early indicator of impeller imbalance or bearing wear
