MAB-204-MDO-Purifier
The Alfa Laval S.p.A. MAB-204-MDO-Purifier is a solids-retaining disc-stack separator configured for purification of marine diesel oil or comparable distillate fuel. It is generally installed in the engine-room fuel-cleaning system upstream of service tanks, booster equipment or engine fuel-system components. The rotating disc-stack bowl separates denser water and suspended solids from the lighter fuel phase. The duty is typically less viscosity-sensitive than heavy-fuel-oil separation, but stable feed conditions and the correct separator setup remain essential. The MAB family is designed for manual removal of accumulated sludge and can be arranged for clarification or purification. The MAB-204-MDO-Purifier should be treated as a specific MDO purifier configuration rather than as automatically interchangeable with HFO or lubricating-oil versions of the same basic separator size. Exact process conditions, capacity and configuration details must be taken from the manufacturer documentation for the installed serial number.

Service & Maintenance
Inspect the bowl, disc stack and sludge space for water-related corrosion, particulate deposits and mechanical damage. Confirm the purifier arrangement after maintenance and verify correct routing of clean-oil and water outlets. Check drive condition, bearings, spindle, seals and any operating-water or discharge system fitted to the exact model. Review downstream fuel quality and separator operating behaviour after reassembly. Use the manufacturer documentation for exact process settings, wear limits, tightening values and maintenance intervals.
