Common failures & inspection points
Visual inspection for fuel weeping at mechanical seal area; measure any drips; verify seal chamber vent hole patency (prevents residue accumulation damaging couplings)
Monitor discharge temperature continuously; K/L series max 180°C (300°C with MAG coupling); verify fuel suitability for elastomer resistance; check cooling system function
Verify internal safety valve function; K series max 16 bar, C series max 100 bar, L series max 63 bar; minimum operating pressure must not fall below 2 bar
Auditory monitoring for abnormal noise (friction/wear); K/L series use sealed, pre-lubricated external bearings requiring no maintenance; verify FKM sealing discs prevent washout
Verify fuel viscosity matches pump spec (K/L: up to 10,000 mm²/s; F series: 0.2-500 mm²/s); confirm chemical neutrality and acid value <0.5 mg KOH/g for F-series biofuels; check elastomer/housing material compatibility with fuel type
