Common failures & inspection points
Inspect mechanical shaft seal for external leakage, carbon face erosion, and seal ring condition; perform dye or soap solution test for micro-leaks; check seal flush/barrier fluid systems on high-pressure variants
Monitor bearing temperature with infrared thermometer (normal: 50-82°C for ISO 68 oil); inspect bearing oil for water content via Karl Fischer test; check oil color for darkening/oxidation; measure bearing vibration levels with portable vibration analyzer
Perform oil analysis for ferrous metal concentration (Fe) and chromium from bearing rings; monitor flow rate trending against original performance data; check for abnormal noise indicating rotor contact; perform ultrasonic inspection for internal cavitation damage
Measure differential pressure at pump suction/discharge; compare to baseline specifications; check for clearance wear via flow decay test; monitor pump amperage/power consumption for trending; inspect suction strainer and discharge filter for restrictions
Perform ISO Cleanliness particle count (ISO 4406 standard); test oil viscosity at 40°C and 100°C against specifications; check acid number (TAN) for oxidation; measure water content (Karl Fischer); perform FTIR analysis for additive depletion and degradation byproducts
