Cooling Water Pump

• Area: Cavitation damage - pitting and cratering on impeller leading edges, casing wear surfaces
  Check: Inspect impeller blade leading edges and pump volute for erosion patterns, pitting, cratering. Install inlet pressure transmitters; baseline trend shows >10% sustained drop indicates strainer/suction piping issues requiring immediate investigation.
• Area: Bearing wear - rumbling noise, loss of bearing preload, increased runout
  Check: Conduct vibration analysis baseline; 25% increase in any axis warrants investigation; 50% increase indicates imminent failure. Listen for grinding/rattling; verify motor current draw against baseline. Monitor bearing temperature if equipped with sensors.
• Area: Wear ring erosion and impeller-to-casing clearance degradation
  Check: Visual inspection of wear rings for abrasion patterns; measure impeller-to-casing clearance with feeler gauges per manufacturer specs. Replace renewable wear rings per maintenance interval (quarterly to annually depending on seawater quality).
• Area: Mechanical seal failure - leakage, internal recirculation, thermal degradation
  Check: Inspect seal faces for wear, corrosion, deposits. Measure seal flush water pressure/flow. Check for weeping or spray from seal cavity. Verify seal water temperature within specification (typically ≤40°C for marine duty). Replace per manufacturer interval or if leakage observed.
• Area: Suction line blockage - reduced inlet pressure, cavitation onset, loss of prime
  Check: Record baseline inlet pressure at pump suction; check sea chest strainer differential pressure regularly. If inlet pressure drops >10% from baseline, inspect/clean sea chest strainer immediately. Verify suction line diameter adequate per installation design.
