Separator/Purifier · Separators & Purifiers
GEA Westfalia Separators & Purifiers. GEA Westfalia Marine Separators are self-cleaning centrifugal separators used for clarification and purification of fuel oil and lube oil on marine vessels. The OSD series (introduced 2000) and newer OSE eagleclass (2008/2010) feature 3-phase AC motor drive with centrifugal clutch and flat belt transmission. The OSE generation delivers 30% energy r

| Bowl disassembly and cleaning | 500-1,000 running hours or per the maker's manual, whichever comes first |
|---|---|
| Gasket/O-ring replacement (bowl seals) | every bowl overhaul, typically 4,000-8,000 hours |
| Frictional lining/clutch inspection | every 4,000-6,000 hours |
| Gear/drive oil change | 2,000-4,000 hours or per the maker's schedule |
| Major overhaul (bearings, spindle, main drive) | 12,000-16,000 hours - confirm against the maker's major overhaul interval |
| Operating water solenoid valve function test | monthly |
Typical intervals for this design class, not the manufacturer’s figures for your model. The manufacturer’s manual is binding.
| Frictional lining thickness | renew once remaining thickness is close to the maker's minimum - confirm the exact figure in the maker's manual |
|---|---|
| Bowl spindle bearing radial play | generally renewed once clearance is well beyond the as-new tolerance - check the maker's limit table |
| Disc stack distribution holes | visible enlargement or heavy scale buildup is generally cause for renewal - confirm against the maker's inspection criteria |
Ranges are typical for this design class. Always confirm against the manufacturer documentation for your serial number.
Fuel oil and lube oil purifiers are typically within Continuous Survey Machinery (CSM) scope where the vessel carries that notation; class checks maintenance records for bowl overhaul intervals, sludge discharge test records and bowl-closed safety interlock function. Keep the maker's service reports and parts-replaced logs on board for survey.
Estimated lifetime: Bowl and rotating assembly commonly run 60,000-100,000 hours between major overhauls with correct maintenance; wear parts such as linings and seals need renewal far more frequently - treat as an approximate range, not a guarantee
