Common failures & inspection points

Verify pump impeller and suction strainer for wear, erosion, or cavitation damage. Compare with baseline per operating hours.

Visual inspection of impeller surface, hard-iron coating integrity, and strainer perforations. Check for pitting in hydraulic surfaces.

Confirm mechanical seal integrity (silicon carbide, tungsten carbide components) for salt-water/corrosive service. Seals degrade with abrasive particle contact.

Run pressure drop test across seal cavity; measure leakage rate at discharge. Inspect seal chamber for contamination ingress.

Verify stator housing insulation breakdown risk in Inox models during continuous operation. Material galvanic compatibility critical in marine bilge service.

Megohm meter (insulation resistance test) across motor windings to ground at 500-1000VDC. Document baseline and trending.

Check cable insulation degradation and connector corrosion, especially submersed 20m+ cable runs with salt spray exposure.

Visual inspect cable jacket for cracks, UV damage, moisture ingress. Measure conductor resistance and insulation resistance annually.

Verify bearing lubrication adequacy under continuous high-speed operation (2760+ RPM small models). Oil degradation accelerates in contaminated-water submersion

Temperature monitoring of bearing housing (should not exceed 65°C). Visual inspection of oil color/clarity in accessible bearing cavities post-operation.
