Common failures & inspection points

Mechanical seal wear and leakage (AFI series with SiC/SiC seals)

Visual inspection for external leaks at shaft seal area; pressure test inlet/outlet; check seal surface for scoring or discoloration

Spindle surface degradation and friction losses (all 3-screw types)

Measure hardness of spindles (must remain within specification); inspect polished surfaces for scratches/pitting using 10x magnification; check for particles in fluid

Pressure and flow deviation from nameplate (indicates internal wear)

Run differential pressure test: measure inlet vs. discharge pressure during operation; compare against max ratings (e.g., ALLFUEL max 40 bar differential); trending over time

Fluid contamination and viscosity out-of-spec (critical for pump life)

Lab analysis of fluid: viscosity (target range per model, e.g., AFI max 1,750 mm²/s); particle count ISO 4406; temperature monitoring (max 150°C for AFI/ALLFUEL)

Cavitation damage and abnormal vibration (indicates suction problems or misalignment)

Acoustic monitoring for high-frequency noise; ultrasonic testing of rotor surfaces; check inlet pressure (max inlet per model); verify pump alignment and mounting bolts
