APPLICATIONS Flottweg AC-Separators for Highly Efficient Clarification and Separation Disc stack centrifuges are high-speed centrifuges for the mechanical separation and clarification of mixtures comprising solids and liquids. Due to their special design, disc stack centrifuges work at a very high rotation speed. As a result, the centrifugal acceleration (g-force) generated by a disc stack centrifuge is extremely powerful. Moreover, the discs included provide a large clarifying area. Thus, it is possible to separate ultrafine solid particles from a liquid and to separate liquid mixtures in...

HOW THE CLARIFIER WORKS Clarification: Two-Phase Separation (Solid-Liquid) Flottweg Clarifiers separate solids from liquids thus enabling high efficient clarification. The product to be clarified enters the interior of the bowl through a stationary inlet pipe and is gently accelerated by the distributor to the bowl speed. Big solid particles are immediately separated in the centrifugal field. The disc stack in the bowl causes the product stream to be divided up into many thin layers, creating a large clarifying area. The solids are separated from the liquid within the disc stack. The high...

HOW THE PURIFIER WORKS Purification: Three-Phase Separation (Liquid-Liquid-Solid) A purifier enables the separation of liquid mixtures with different densities and solids at the same time. In a purifier (three-phase disc stack centrifuge), the product to be separated enters the inside of the bowl through a stationary feed pipe and is gently accelerated by the distributor to the bowl speed. Big solid particles are immediately separated in the centrifugal field. The disc pack in the bowl causes the product stream to be divided up into many thin layers, creating a large clarifying area. The...

THE FLOTTWEG THE FLOTTWEG SOFT SHOT® SOFT SHOT® SYSTEM SYSTEM Precise, Silent and Economic Flottweg AC disc stack centrifuges are equipped as a standard with the hydraulic Soft Shot® discharge system. This bowl valve system offers various advantages for the customer: The heart of the Soft Shot® discharge system consists of two bowl valves. The mass of these valves has deliberately been kept low. Thus system inertia is reduced and the system is triggered almost exclusively by the operation water pressure inside the bowl. In contrast to other systems, these valves work at a very high speed....

INERT GAS PURGING If centrifuges are used to process products whose vapors together with oxygen may form a flammable mixture, there is a risk of explosion. Consequently, inert gas purging systems are used to prevent the exit of vapors into the atmosphere (contamination) as well as to avoid the entry of air into the system (explosion). Flottweg offers centrifuges including an inert gas purging concept which is perfectly adapted to the requirements of these applications and in compliance with the highest safety standards.
