Common failures & inspection points

Stator elastomer wear and material degradation from saltwater/chemical exposure

Visual inspection for hardening, cracking, swelling; micrometers for wall thickness reduction; material compatibility cross-check with cargo type (fuel, sludge, seawater ballast)

Mechanical seal leakage and loss of lubrication film on rotor (dry-running risk)

Leakage detection at shaft seal cavity; rotational drag test under no-flow priming; seal cartridge clearance verification with feeler gauge; lubrication film observation during low-speed commissioning rotation

Rotor/stator cavity clearance increase leading to reduced volumetric efficiency and slippage

Dial gauge measurement of rotor runout; comparison of current displacement (mL/rev) against datasheet baseline; pressure/flow curve trending over service life; bore diameter verification with precision calipers

Joint seal and fastener corrosion/galling under marine salt-spray and vibration environment

Visual inspection for white corrosion products on connection surfaces; thread-locking compound integrity check; bolt torque verification per maintenance manual; ultrasonic or visual crack detection of fasteners

Cavitation damage on rotor/stator surfaces from inadequate net positive suction head (NPSH) during sludge/bilge pumping

Visual pit/erosion pattern mapping on rotor tip and stator bore with borescope; suction line pressure gauge trending; prime-loss incident log review; stator replacement interval comparison vs. design baseline
