GEA Westfalia OSD-6-91-067
Core Functionality
Advanced Centrifugal Separation
-
Self-cleaning disc stack bowl: Uses high centrifugal forces to efficiently separate water, sludge, rust, sand and other contaminants from oil streams.
-
Fuel-oriented design: Optimized for lighter fuels such as diesel and marine gas oil, as well as compatible with a wide range of lubricating oils.
-
Pressure discharge: Clean oil is discharged under pressure via a centripetal pump, simplifying reintegration into engine or system circuits.
Robust Mechanical Design
-
Constructed with industrial-grade materials for high durability and corrosion resistance in marine engine rooms and industrial plants.
-
Drive system typically includes a flange-mounted vertical motor arrangement providing stable, continuous operation.
-
Hinged hood and solids collector allow straightforward access for maintenance and inspections.
Key Specifications (Typical)
-
Max bowl speed: ~12,000 rpm
-
Rated throughput: ~2000 L/h (depending on application and fluid)
-
Motor power: ~4 kW (e.g., 380/690 V, 3-phase AC, 50/60 Hz)
-
Construction: Stainless steel and heavy-duty industrial components
-
Discharge: Pressure-driven clean oil and separated impurities.
Typical Marine Applications
✔ Fuel Oil Purification:
Ensures high-quality diesel or marine fuel before combustion in main engines, auxiliary engines, and generators, reducing injector wear and improving combustion efficiency.
