Flottweg's disc stack centrifuges epitomize German engineering excellence, offering robust purification and clarification for a diverse range of applications. These separators stand out with their impressive centrifugal accelerations of over 12,000 g, optimizing liquid processing beyond the limits of decanter centrifuges. The innovative disc stack design ensures efficient solids separation and maximized liquid phase purity, while the Soft Shot® discharge system guarantees smooth operation with accurate partial and full discharges in any combination. Flottweg's separators are not only powerful, thanks to their three-phase standard motors and belt drives, but also offer flexible speed regulation and efficient lubrication systems for long-term reliability. Safety is paramount, with all components manufactured to withstand the rigors of high-force operations, ensuring a continuously safe separation process. Tailored to meet specific customer requirements, these separators integrate seamlessly into existing systems, marking them as the final stage in a comprehensive purification process.
Disc centrifuges for clarifying and separating liquids
From algae harvesting to beer clarification and protein extraction: If you want to separate or purify liquids or remove ultra-fine particles you need powerful and robust separators. With their enormous centrifugal acceleration of up to over 12,000 g, Flottweg separators are real purification and clarification all-rounders - highest quality made in Germany.
The right disc separator for your application
Where decanter centrifuges reach their performance limits, separators come into play. Thanks to their higher speeds, they are able to process liquids optimally. Do you want to separate finest solid particles from a liquid? Then a clarifying separator (2-phase separation) is the right solution. Do you need to separate liquid phases of different densities while simultaneously separating solids? Then a purification separator (3-phase separator) is required.
In addition, Flottweg's know-how as a system partner is of great importance, as separators are often the last stage in an extensive separation process. They are often combined with an upstream decanter or Tricanter®. Flottweg customizes the process to the customer's requirements and also finds the best possible separator solution that can be integrated into existing piping and plant systems.
Flottweg disc stack separators are available in two basic designs and are suitable for a wide range of applications:
How the Flottweg separator works
Through high-precision centrifugation, separators efficiently separate operating fluids into solids and heavy and light liquid phases – continuously, gently, and fully automatically during ongoing operations.
1. Infeed:
The product to be separated flows into the inside of the drum via an infeed pipe.
2. Acceleration:
Inside, a distributor gently accelerates the liquid to full speed.
3. Separation in disk pack:
The product flow is divided into many thin layers in the disk pack. This creates a large separation surface.
4. Solids separation:
Solids are separated from liquids through centrifugal force and separated at the edge of the bowl.
5. Solids discharge
A hydraulic system in the bottom of the bowl periodically discharges the collected solid particles at maximum speed.
6. Fluid drainage (clear phase)
A centripetal pump discharges the clarified fluid under pressure.

Soft Shot®
The solids discharge of a Flottweg separator is performed by the patented Flottweg Soft Shot® FLEX discharge system. The system allows a precise and user-defined combination of partial and full emptying. Depending on the products to be processed and the consistency of the solids, the type of discharge can be adjusted to ensure highly efficient operation.
Further information about the system can be found here: Soft Shot® FLEX
Hydrohermetics
The option for 2-phase separators seals the product space from the ambient atmosphere. As a consequence, this feature prevents unwanted oxygen absorption and the formation of foam. The hydrohermetic design of the disk separator consists of a stationary disk which is immersed in a liquid (e.g. degassed water) and thereby creates a seal to the immediate environment.

Centripetal Pump
The centripetal pump ensures optimum discharge of the clarified liquids from the centrifuge. It discharges the clarified liquid under pressure from the separator bowl and prevents the product from foaming.

Lubrication system
A lubrication circulation system ensures fully automatic lubrication of the bowl spindle bearings. It lubricates the bearings regularly with an optimum oil quantity. This enables precise and speed-independent lubrication.
Further information: Lubrication system
Disc stack
The actual splitting up of the liquid mixture takes place in the separator bowl disc stack. The disc stack consists of a large number of vertically arranged conical individual discs. The disc stack increases the clarifying area in the separator bowl and thereby the separation efficiency.
