Lube oils face constant contamination from dust, acids and catalyst residues. GEA separators ensure continuous cleaning for reliable, cost-efficient operation.

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.
Contaminated lube oil leads to increased wear, reduced engine efficiency and costly downtime. Regular and efficient treatment of lube oil is essential to:
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.
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:

Sustainable lube oil management with centrifugal separation

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...

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.
Since 2019, GEA has risen from underperformer to DAX member – one of Germany's top 40 listed companies – by fostering entrepreneurship and turning sustainability into a competitive advantage. It reached this milestone in its nearly 145-year history without tailwinds or shortcuts, in a world of compounding crises. This turnaround shows what's possible when purpose and performance align.
This year was a big one for GEA. Can you remember all the milestones and highlights?
The GEA Foundation launched this year with a promise: to make a tangible difference in people's lives. From scholarships in Germany to clean water in Tanzania, the foundation is already proving that when companies commit to giving back, lives change.
