Pump

• Area: Bearing temperature elevation above normal baseline (monitor continuously; sharp increase indicates lubrication failure or wear)
  Check: Use non-contact infrared thermometer to check bearing housing temperature; establish baseline temperature during commissioning; trend data over time
• Area: Abnormal vibration levels indicating misalignment, imbalance, bearing wear, or other mechanical issues
  Check: Periodically monitor vibration with vibration analyzer; conduct vibration analysis by trained technician; identify bearing defects, resonance, and misalignment patterns; compare to baseline readings
• Area: Mechanical seal leakage or loss of seal integrity leading to system contamination and pump failure
  Check: Inspect all connections, seals, and joints for visual signs of leakage; monitor seal drip rate; check seal housing and mating surfaces for wear; address leaks immediately to prevent progression
• Area: Cavitation damage to impeller and internal components caused by low suction pressure or vapor bubble collapse
  Check: Listen for cavitation noise (audible as crackling/popping); monitor NPSH (Net Positive Suction Head) margin; check for pitting/erosion on impeller surfaces; verify suction conditions; maintain adequate suction pressure
• Area: Impeller and casing wear, corrosion, pitting, or erosion reducing pump efficiency and performance
  Check: Annual disassembly for internal inspection; examine impeller for grooves, pitting, or erosion; inspect casing for material loss exceeding 1/8-inch depth; replace components showing excessive wear; photograph wear patterns for trend analysis
