MAHLE Pi 230 DN80

MAHLE MAHLE Pi 230 DN80 is identified in the source list as a fuel-oil filter. It is normally installed in the engine-room fuel treatment or supply system upstream of engines, pumps or other contamination-sensitive equipment. Its purpose is to remove solid contamination from fuel and protect downstream injection and pumping equipment. The source record provides the stated capacity or size information DN80. Depending on the model it may use simplex, duplex, automatic backflushing or another filtration arrangement, which must be confirmed from the installed documentation. The exact model designation and source-listed connection or capacity information distinguish filter size and arrangement from neighboring units; refer to the manufacturer documentation for the exact filtration grade and flow data.

Common failures & inspection points

●Filter-element blockage caused by contaminated fuel, sludge or abrasive particles, resulting in rising differential pressure and reduced downstream fuel pressure
●Automatic backflush failure where fitted caused by actuator, control or valve faults, resulting in repeated high differential pressure
●Seal or cover leakage caused by damaged gaskets or incorrect assembly, resulting in visible fuel leakage
●Internal bypass or damaged element caused by incorrect fitting or collapse, resulting in inadequate filtration and contamination downstream
●Heating or viscosity-related restriction caused by fuel being unsuitable for the operating condition, resulting in excessive pressure drop and poor flow

Service & Maintenance

Monitor differential pressure and downstream fuel pressure and investigate rapid fouling rather than repeatedly bypassing the filter. Inspect elements, baskets, backflush mechanisms, covers, drains and seals for contamination and damage. Maintain fuel temperature and viscosity conditions appropriate to the vessel's fuel system. Clean or replace elements using the approved procedure and prevent dirt entering the clean side during maintenance. Check automatic changeover or backflush functions where fitted. Refer to manufacturer documentation for exact element grade, differential-pressure limits and servicing criteria.

Replacement Parts

Keep model-correct filter elements or candles, cover gaskets, O-rings, backflush valve or actuator service parts and differential-pressure instrumentation spares as recommended. Carry sufficient consumables for expected fuel-quality variability and voyage duration. Verify exact filtration grade and materials before installation.
