Flottweg
Nozzle Separator

Flottweg nozzle separators (2- and 3-phase nozzle separators) are used for the continuous separation of solids from liquids and ensure highly efficient clarification or separation. The product to be clarified or separated flows via a stationary inlet pipe into the inside of the bowl and is gently accelerated to operating speed by the distributor.

Large solid particles are separated directly in the centrifugal field of the 2-phase nozzle separator. Finer solids are separated when flowing through the disc stack. The solid particles collect in the bowl’s outer solids chambers. From there, they are continuously discharged via the nozzles. The clarified liquid flows from the disc stack and is discharged under pressure by an impeller.

Our separation technology experts have developed the Flottweg nozzle separator in collaboration with our customers. The goal: a nozzle separator perfectly tailored to the needs of our customers. The result: an innovative, energy-optimized low-wear design.

Throughout the development of our nozzle separators, the focus was on maximum energy savings, and thus on low energy costs. Our revolutionary bowl design saves drive energy. In addition, the bowl of our nozzle separator is significantly lighter than conventional bowls and therefore requires less drive energy. The separator bowl design ensures reliable and low-vibration operation. Solids chambers integrated into the bowl prevent uncontrolled sediment formation and can avoid vibration. The concentrate can be conveyed out of the bowl via the solids chambers without leaving deposits. The size of the nozzles' outlets is optimally adapted to the respective process and to the product to be processed.

The rapid acceleration of separators depends on a powerful drive with a long service life. Flottweg supplies a standard three-phase AC motor to provide the necessary power. It transmits the power to the bowl spindle by means of a belt and runs very smoothly. The speed can be easily and flexibly adapted to the respective product conditions via a frequency converter. The separator quickly reaches full operating speed. At the same time, the inverter reduces both the power consumption and the mechanical load on the system. A completely closed lubricating circuit system protects the spindle bearings. Full lubrication capacity is available during the start-up and shut-down of the machine, which ensures that the bowl’s bearings have a long service life. A pump unit ensures exact and demand-oriented metering of the lubricating oil.

Fast and predictable maintenance makes a decisive contribution to smooth operation. The innovative design of the separator bowl prevents wear. The arrangement of the nozzles creates a natural wear protection of solid material in the bowl. The nozzles of the Flottweg Nozzle Separator are equipped with carbide wear protection for maximum service life. These nozzles can be replaced quickly and easily via a maintenance opening in the housing. The nozzle separator's compact spindle drive is also optimized for minimum downtime during maintenance. This can be removed quickly and easily with little effort. The separator drive belt can be easily retightened or quickly replaced through a maintenance opening. High-quality materials 'Made in Germany' ensure that maintenance intervals are extended. For our customers, this means higher availability and low costs.

Flottweg has a worldwide service network of competent service technicians for maintenance and servicing. This means that your local service partner is quickly available should service be required.

Whether food, biotechnology, or chemicals, Flottweg separators are fully equipped to meet the hygienic requirements in highly regulated industries. They meet all requirements of the applicable centrifuge standard and are constructed according to the principles of "Hygienic Design." The innovative solids chambers in the separator bowl ensure that the concentrate is discharged from the bowl without deposits and that no deposits remain when the machine is shut down. All components of the separator that come into contact with the product are made of high-quality stainless steel. The hygienic design of the Flottweg nozzle separator avoids dead spaces and thus enables easy cleaning of the centrifuge. In the food and biotechnology industries, all components that come into contact with the product are CIP-capable (Clean-in-Place) and can be easily integrated into existing cleaning processes.
