With the new decanter centrifuge Z8E (Fig.), Flottweg considerably enlarges the capacity range of its decanters and is setting new bench-marks: The new Z8E is one of the largest (three-phase) decanter with an adjustable impeller on the market. With the adjustable impeller, the fluctuations in the feed can be evened out automatically while the machine is running. At the same time, the fluid level in the decanter can be optimally readjusted. The centrifuge is universally applicable. Thanks to its modular design this decanter can be customized to the specific demands of each industry. For the chemical industry, gastight machines with ATEX certified equipment are currently being developed. The new Z8E model is available in two-phase as well as three-phase versions. All functions of the machine can be integrated into the overall control system of the process. In order to meet the demands of this design size, Flottweg has also upgraded the size and efficiency of the proven SIMP-DRIVE® system.
