Lube oil treatment for diesel engines
Lube oils face constant contamination from dust, acids and catalyst residues. GEA separators ensure continuous cleaning for reliable, cost-efficient operation.
Protecting your engine, extending oil life
Diesel engines face tough conditions - and so does their lube oil. During operation, the oil is constantly exposed to contaminants like dust, metal particles, water and chemical residues. These impurities speed up oil aging and can lead to increased wear and reduced engine performance.
Trunk piston diesel engines are especially vulnerable. Under partial load, unburned fuel and combustion residues can enter the crankcase. When these mix with water vapor, they form acidic compounds that can damage critical components such as bearings, pistons and cylinders.
The importance of effective lube oil treatment
Contaminated lube oil leads to increased wear, reduced engine efficiency and costly downtime. Regular and efficient treatment of lube oil is essential to:
- Remove solid and liquid contaminants
- Prevent corrosion and premature engine wear
- Extend the service life of both oil and engine components
- Reduce maintenance costs and environmental impact
Maximum engine protection with minimal effort
Centrifugal separation is the most effective and widely used method for lube oil treatment. In this process, a separator is installed in a bypass loop within the engine’s lube oil system. The separator efficiently removes water, sludge and particulate matter, ensuring the oil remains clean and fit for use.
For applications requiring 24-hour unattended operation, self-cleaning mineral oil centrifuges are the preferred choice. These systems automatically discharge separated contaminants, minimizing manual intervention and maximizing uptime.
GEAs solutions for lube oil treatment
GEA offers a comprehensive range of high-performance centrifuges designed specifically for the purification and dewatering of lube oils in diesel engines. Our solutions are engineered for efficiency, reliability and ease of maintenance:
- Modular design: All GEA fuel and lube oil treatment centrifuges share identical design features, allowing for the use of common components. This simplifies spare parts management and streamlines maintenance.
- Proven performance: GEA centrifuges deliver consistent, high-quality oil purification, reducing engine wear and extending oil change intervals.
- Unattended operation: Our self-cleaning centrifuges are ideal for continuous, around-the-clock operation, ensuring your engines are always protected.

Centrifugal Separator
GEA separators are designed for liquid-based applications. Using centrifugal force, they are used for separating suspensions consisting of two or more phases of different densities, i.e. they can be used for liquid-liquid separation, for liquid-liquid-solid separation or for liquid-solid separation. They are equally as effective at separating liq...
Machine automation & control
Every plant or machine, which is designed for a reliable long-term operation, requires a control unit that enables the communication between the different system parts. It is one of the most important component that guarantees reliability and efficient operation.
