The GEA Westfalia OTA 7-00-066 is a solid-wall disc-stack centrifugal separator designed to separate liquids and solids efficiently — especially where liquid mixtures contain water, sludge, particulates, or contaminants that need to be removed from oil or other fluids.

GEA Westfalia OTA 7-00-066

Key Features

✔ Type: Solid-wall disc-stack separator (disc centrifuge).
✔ Separation: Uses centrifugal force to separate heavier phases (water, solids) from lighter fluids (clean oil).
✔ Construction: Robust design with a hinged hood and sediment collector for easy cleaning and maintenance.
✔ Drive: Flange-mounted horizontal motor delivers stable power for high RPM rotation of the bowl.
✔ Typical Specs: Many units documented with a 3 HP motor and max bowl speed ~9,600 rpm, processing around 2,900 L/h (~12 GPM).
✔ Materials: Often built in 316 stainless steel for corrosion resistance in marine/industrial conditions.

What it does:
It clarifies and purifies liquids — particularly oils — by removing water, sludge, and solid impurities, improving fluid quality and protecting downstream equipment.

 Marine Department Uses

In marine applications, the OTA 7-00-066 functions as a centrifugal oil purifier/clarifier:

🔹 Fuel Oil Cleaning

• Removes water, solids, and sludge from diesel and fuel oil stored on ships.

• Clean fuel prevents injector clogging, reduces corrosion, and improves combustion efficiency.

🔹 Lube Oil Clarification

• Purifies lubricating oils for engines, gearboxes, and generators.

• Reduces wear and extends equipment life by preventing abrasive particles from circulating.

🔹 Hydraulic Oil Purification

• Cleans hydraulic fluids in steering gear, deck machinery, and ancillaries.

• Clean hydraulics improve pump and valve life and reduce maintenance issues.

🔹 General On-Board Liquid Quality Control

• Handles stored oils that have accumulated water or solids during storage or handling.

• Smooth operation of machinery and reduced downtime.

Why it suits marine use:
Marine separators must tolerate motion, vibration, and changing fluid qualities while reliably protecting critical engine room systems. GEA’s centrifugal technology is built for this continuous, robust performance.

 Industrial Department Uses

In industrial settings, the OTA 7-00-066 helps improve liquid quality and protect machinery in many applications:

🔸 Industrial Oil & Fluid Clarification

• Removes solids and contaminants from hydraulic oils, gear oils, compressor oils, and other industrial lubricants.

• Cleaner fluids reduce wear on pumps, bearings, and industrial equipment.

🔸 Fuel Treatment

• Clarifies diesel or other fuels before use in industrial engines or generators.

• Improves combustion and reduces fouling in burners or injectors.

🔸 Liquid-Solid Separation

• Separates contaminants from liquids in chemical, petrochemical, or processing industries where solids need removal before further use or disposal.

🔸 Recycling & Waste Oil Recovery

• Helps recover usable oil from waste streams by removing solids and water.

• Reduces disposal costs and supports environmental and plant efficiency goals.

  Benefits of Using the OTA 7-00-066

  ✔ Efficient separation: High centrifugal force provides good removal of water and solids from liquids.
  ✔ Robust construction: Stainless steel and solid design for marine/industrial durability.
  ✔ Reliable performance: Suitable for continuous operation in engine rooms and production environments.
  ✔ Lower machine wear: Cleaner oil reduces wear on pumps, engines, hydraulics.
  ✔ Versatile use: Works for fuel oils, lubricant oils, hydraulic fluids, and other process liquids.
