The GEA Westfalia OSD-6-91-067/6 is a self-cleaning disc-stack centrifugal oil separator engineered for continuous purification and conditioning of fuel and lubricating oils in demanding marine and industrial environments. It is part of the robust OSD-6 series of separators from GEA Westfalia, designed to improve oil quality, protect engines and systems, and reduce maintenance costs.
GEA Westfalia OSD-6-91-067/6
Core Functionality & Technology
High-Efficiency Centrifugal Separation
-
Uses a self-cleaning disc stack bowl that generates high centrifugal forces to remove water, solids and contaminants from oil effectively, enhancing oil quality and system reliability.
-
Optimized for lighter fuel oils (e.g., diesel and similar fuels) often used in marine and industrial engines, as indicated by the “91” designation.
-
Pressure discharge of clean oil: Clean oil is discharged under pressure via a centripetal pump for easy reintegration into fuel or lubricant circuits.
Robust Mechanical Design
-
Typically equipped with a 4 kW, 3-phase electric motor (e.g., 380/690 V, 50/60 Hz) providing reliable continuous duty performance.
-
Designed with industrial-grade components including a disc-stack bowl, hinged hood, and solids collector that facilitate easy maintenance and access.
-
Flange-mounted motor with vertical arrangement ensures stable and consistent drive performance.
Typical Performance
-
Rated throughput: Approx. 2000 L/h (varies by oil type and setup).
-
Maximum bowl speed: Up to 12,000 rpm for effective separation.
Applications
Marine Department
✔ Fuel Oil Purification: Removes water and solid impurities from marine diesel and gas oil before use in main engines and auxiliary generators, reducing injector wear and improving combustion stability.
✔ Lube Oil Conditioning: Enhances the quality of lubricating oils used in engines, compressors and turbines by removing contaminants.
✔ Engine Room Systems: Continuous duty operation supports long-term engine room reliability in commercial vessels, offshore ships, tankers, and support craft.
Industrial Sector
✔ Power Generation: Purifies diesel/gas turbine fuels and lubricants to maintain generator efficiency and reduce unscheduled downtime.
✔ Heavy Machinery Operations: Keeps hydraulic and lubricating oils free of water and particulates, extending machinery life and lowering maintenance frequency.
✔ Oil Handling & Storage: Ideal for conditioning stored fuel or lubricant before use, enhancing system performance across industrial facilities.
Benefits
🌟 Improved System Reliability: Cleaner oil reduces wear, corrosion and deposits in engines and machinery.
🌟 Lower Operating Costs: Reduced frequency of oil changes and less disposal of contaminated oil.
🌟 Continuous 24/7 Operation: Designed for long, uninterrupted service in harsh environments.
🌟 Easy Maintenance: Hinged hood and accessible components simplify servicing.
