Fuel Oil Separator · Separators & Purifiers
Datasheet on file — the values below have not yet been checked against it.
| Bowl disassembly and cleaning | typically every 4,000-8,000 running hours per Alfa Laval's recommendation, adjusted to fuel quality experienced |
|---|---|
| Seal/gasket kit replacement | at each major bowl overhaul |
| Bearing replacement | commonly in the 8,000-16,000 hour range for this separator class - confirm against the unit's own service manual |
| Gravity disc/dam ring check | whenever fuel density changes significantly |
| Bowl running hours since last overhaul | track against Alfa Laval's stated interval for this bowl size rather than a fixed number, since it depends heavily on fuel contamination level |
|---|---|
| Disc stack condition | reject on visible pitting, deformation, or clogging that cleaning does not remove |
Ranges are typical for this design class. Always confirm against the manufacturer documentation for your serial number.
Fuel oil separators are a Continuous Survey Machinery item on many class notations - class checks running hour records, overhaul history, and that bowl speed/vibration and discharge water oil content are within normal limits at survey; keep the overhaul log and spare parts consumption record available.
Estimated lifetime: The separator frame and gearbox are typically designed for long service life (many tens of thousands of hours) with periodic bearing and seal renewal; the bowl requires interval overhaul as above rather than outright replacement under normal operation.
