Fuel contamination and its impact
Fuel contamination can occur at various stages throughout the supply chain, from transportation and storage to day-to-day operation.
Typical contaminants include:
- Water from condensation
- Dirt and dust particles
- Corrosion products from storage tanks
- Rust particles
- Sediments and sludge
Even small amounts of contamination can lead to increased wear, injector damage, blocked filters and reduced engine efficiency. Modern high-performance diesel engines are particularly sensitive to water and fine particles, making reliable fuel treatment essential.
Fuel polishing with centrifugal separation
Fuel polishing is the continuous removal of water and contaminants from stored diesel and fuel oils to maintain fuel quality and protect equipment.
GEA centrifugal separators remove free water and fine solids in a single process step, ensuring consistently clean fuel for engines, generators and fuel distribution systems.
Installed in a bypass or dedicated fuel treatment system, GEA separators continuously condition the fuel while minimizing maintenance requirements. Compared with conventional filtration systems, centrifugal separation reduces filter loading while providing highly efficient contaminant removal.
By continuously maintaining fuel quality, operators can reduce engine wear, minimize downtime and extend the service life of critical equipment. The result is improved equipment reliability, longer component life and lower operating costs.

Fuel & diesel oil treatment with centrifugal separators
Where fuel polishing makes a difference
Whether fuel is stored for days, weeks or even months, fuel polishing helps prevent the accumulation of water, sediments and other contaminants that can reduce fuel quality and impact equipment reliability.
GEA solutions help ensure reliable fuel quality in applications such as backup power systems, vehicle fleets, fuel depots, mining operations, agricultural equipment and industrial facilities.

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...

Jet pumps
Jet pumps, also referred to as ejectors, are devices for the conveyance, compression or mixing of gases, vapors, liquids or solids and for the production of vacuum in which a gaseous or liquid medium serves as the motive force.

Liquid Mixers
Mixing is a vital process in the production of a diverse range of products in a wide range of industries. Based on our extensive experience and technological know-how, GEA offers a variety of batch, continuous and in-house custom designed mixing solutions for unique applications that meet specific customer needs.

The water equation
Across Europe, drought is a recurring reality – and no longer confined to the south. While water increasingly shapes where industries locate, its value is determined by local context. There are many technological routes to water efficiency in industrial processes, but location, energy needs and other factors are also key.
