Lube Oil Pump

• Area: Mechanical seal degradation or leakage
  Check: Monthly inspection of seal faces for surface roughness exceeding Ra 0.8μm, visible scoring, corrosion pitting, and leakage rate. Check springs for >15% compression loss or corrosion. For marine saltwater environments, verify electropolished 304-grade stainless steel material. Accept minor imperfections <0.05mm depth only (polish out), deeper damage requires shaft sleeve and seal renewal.
• Area: Bearing wear and failure - noise/vibration/temperature increase
  Check: Quarterly monitoring of bearing condition via vibration analysis (compare to baseline), bearing housing temperature (target <80°C for normal operation), audible noise (grinding, squealing indicates wear), and lubricant oil samples for metal wear particles. Use thermocouples for direct bearing outer ring temperature measurement. Premature failure typically caused by lubrication starvation, contamination, or misalignment - check bearing clearances and shaft alignment within 0.1mm on coupling concentricity.
• Area: Rotor/screw internal wear and corrosion pitting
  Check: Yearly inspection of internal screw and casing clearances: rotor-to-bore maximum 0.2mm, between rotor flanks maximum 0.4mm. Use borescope or remove inspection covers to check for internal scratches, scoring, or corrosion pitting. Casing material examination for stress corrosion cracking in cemented carbide components. Complete overhaul required not exceeding 3 years. Discard rotors with scoring exceeding 0.2mm depth.
• Area: Suction line blockage and cavitation - low flow/high noise
  Check: Check strainer and inlet screen monthly by monitoring suction pressure reduction (gradual drops indicate clogging). Verify suction piping for blockages, air leaks into suction line, and adequate net positive suction head (NPSH). Prime pump completely with working liquid before startup. Inlet pressure must not exceed 25-75 PSIG depending on pump type. Cavitation creates vapor bubbles causing noise, vibration, and rotor/impeller damage - verify pump inlet pressure at <6 bar (self-priming design requirement).
• Area: Coupling misalignment and shaft seal leakage
  Check: Pre-installation: verify pump and motor shaft concentricity within 0.1mm on coupling outer circle, maintain 2-4mm gap between coupling planes (0.3mm tolerance). Post-installation: periodic inspection of foundation bolts torque, coupling wear, and shaft seal integrity (leakage should not exceed 10 drops per hour). Rotate pump-motor coupling by hand to confirm smooth operation. Any resistance or grinding indicates internal bearing damage. Replace shaft seals if leakage is excessive.

  Check: Verify lube oil filter condition (change after 250 operating hours minimum). Test oil viscosity, total acid number (TAN), and particle count per ISO 4406. Confirm inlet/outlet strainer mesh integrity (60-mesh recommended for light oils, 100+ mesh for HFO). Check for water content/emulsification.
• Area: Bearing wear, lubrication starvation, or thermal issues
  Check: Monitor bearing temperature trends during operation (excessive heat = 60-70°C+ above ambient). Check external grease pack condition on permanently greased bearings. Inspect bearing races for spalling or pitting. Verify inlet pressure within specifications to prevent cavitation damage.
• Area: Cavitation or operational boundary violations
  Check: Verify inlet pressure is above minimum (avoid negative head). Test discharge pressure against rated maximum for each series (e.g., 150 PSIG for 3E, 2200 PSIG for 12D). Monitor viscosity range (33-3000 SSU typical). Confirm speed limits not exceeded per model/size rating.
