The GEA Westfalia OSD 35-0136-067 is a self-cleaning centrifugal mineral-oil separator manufactured by GEA Westfalia Separator. It’s designed to continuously purify and clarify oil — removing water, sludge, and solid contaminants from fuel and lubricating oils using centrifugal force.

GEA Westfalia OSD 35-0136-067

Key Technical Features

• Type: Self-cleaning disc-stack centrifugal separator (built-in automatic ejection of sludge).

• Model: OSD 35-0136-067 (also related to OSD 35-0196-067 in manuals).

• Application: Oil clarification and purification.

• Operation: Rotates at high speed (typically 8,200 rpm+) with a self-cleaning bowl.

• Throughput: Can handle high oil flow rates — up to around 20,000 L/h or more depending on setup.

• Control systems: Often equipped with automatic monitoring such as WMS (Water Monitoring System) and SMS (Sludge Monitoring System) to optimize performance and trigger automatic ejection when required.

• Design: Stainless-steel bowl and alloy frame with self-cleaning hydraulics built for rugged service.

In essence, it’s a continuous, high-capacity oil purifier that maintains cleaner oil with less manual intervention.

 Marine Department Uses

In marine applications (ships, offshore platforms), the OSD 35-0136-067 is widely used because clean fuel and lube oil are critical for engine reliability and efficiency.

🔹 Fuel Oil Treatment

• Cleans heavy and diesel marine fuels of water and solids before injection into main and auxiliary engines.

• Cleaner fuel reduces wear on injectors and pumps, and improves combustion efficiency.

🔹 Lube Oil Purification

• Removes contaminants from lubricating oil used in bearings, gearboxes, turbines, and auxiliary machinery.

• Extends oil life and protects expensive mechanical components.

🔹 Hydraulic Oil Quality Control

• Ensures hydraulic systems (steering gear, deck machinery) operate with clean fluid, reducing the risk of pump and valve issues.

🔹 General Fluid Conditioning

• Maintains fluid quality on long voyages or during heavy operation, contributing to safety and reduced engine-room maintenance.

Marine separators like this are built to withstand vibration, motion, and continuous duty typical of shipboard environments.

Industrial Department Uses

In industrial settings, the OSD 35-0136-067 plays similar roles where fluids need regular cleaning to protect equipment and processes:

🔸 Fuel Treatment

• Clarifies industrial fuels used in generators, boilers, and turbines, improving performance and reducing soot formation.

🔸 Lubricating and Process Oil Purification

• Removes salts, water, and particulates from oils in manufacturing plants, heavy machinery, and large compressors.

🔸 Oil Recycling and Waste Oil Recovery

• Helps reclaim usable oil from waste streams by removing contaminants, lowering disposal costs and environmental impact.

🔸 Chemical and Petrochemical Processes

• Clarifies oils used in various process steps, ensuring consistency and protecting downstream equipment.

Because it’s a continuous self-cleaning separator, it’s ideal for high-duty industrial processing with minimal manual bowl cleaning.

Benefits & Operational Notes

Key advantages
✔ High throughput with continuous operation – suitable for large marine installations or industrial oil systems.
✔ Automatic sludge handling – built-in automatic ejection reduces downtime.
✔ Versatile – suitable for fuel, lube, and hydraulic oil cleaning across industries.
✔ Monitoring systems – WMS/SMS improve automated control and safety.

Considerations

• Requires correct feed conditioning (temperature, particle size limits) for best separation efficiency.

• Routine maintenance per manufacturer manual is essential.
