Separator/Purifier · Separators & Purifiers
The Alfa Laval S.p.A. MAPX-205-HFO-Clarifier is a legacy high-speed disc-stack oil separator configured for heavy fuel oil clarification. It is normally installed in the machinery-space fuel treatment system to reduce suspended solid contamination in conditioned fuel. In clarifier service the primary duty is solids removal rather than continuous separation of a defined water phase. Centrifugal force drives denser contamination away from the cleaned oil as the fuel passes through the rotating bowl and disc stack. The MAPX designation belongs to an older Alfa Laval separator family; the exact sludge-handling and operating-water arrangement varies by specification and must be checked in the applicable instruction book. Compared with the corresponding purifier version, the MAPX-205-HFO-Clarifier uses a clarifier arrangement and must be assembled and operated accordingly. Exact throughput, permissible feed conditions, bowl arrangement and service limits must be verified from the manufacturer documentation for the installed unit.

What our service work and the manufacturer documentation say about keeping this model running.
Open and inspect the bowl and disc stack according to actual contamination load and the manufacturer maintenance plan. Confirm that the machine is assembled in its clarifier configuration and that all bowl components are correctly positioned. Check sludge characteristics because unusual metal, catalyst fines or other debris may indicate upstream contamination or machinery problems. Inspect the drive, bearings, spindle, seals and any operating-water or sludge-discharge mechanism fitted to the separator. Refer to the exact manual for wear limits, cleaning procedures, tightening values and operating settings.
Keep the correct seal and service kits for the exact clarifier specification. Additional spares should reflect the installed drive and discharge arrangement and may include bearings, gaskets, valve parts and selected bowl-service components. Match critical parts by serial number and parts catalogue rather than by family name alone.
