The adjustable impeller extends the application range of decanters by enabling the liquid discharge to be adjusted during operation as required. As a result, the decanter can be tailored to a wide variety of applications and process demands. Adjusting the impeller position allows precise control of the liquid level inside the bowl, creating optimal conditions for efficient separation of liquid and solid phases.
As a proven Flottweg system, the adjustable impeller supports high process stability and helps improve separation performance and product yield. Its robust design and ease of use ensure reliable and long-lasting operation.
Every application has its own specific separation requirements. To meet these requirements, the impeller disc concept combines three key features: maximum separation resolution, high flexibility, and easy cleaning. The precise adjustability of the impeller allows for exact adaptation to different products and process conditions. Thanks to the finely adjustable position and the variably adjustable diameter, separation performance can be specifically optimized and adapted to the respective requirements. The concept is complemented by an innovative rinsing system with an optimized nozzle arrangement and a deposit-free design, which ensures reliable cleaning and hygienic process control.
Optimal adjustment of the liquid level is a critical factor for separation in the decanter. Depending on the setting, both the purity of the liquid phase and the dewatering of the solids can be specifically controlled. Adjustments can even be made during operation, offering maximum flexibility in response to changing process requirements.

In addition to precise adaptation to different applications, the adjustable impeller offers simple and user-friendly operation. Adjustment can be performed either manually using a hand wheel or automatically via a drive. This allows the impeller position to be adjusted quickly, precisely, and reproducibly. The automatic adjustment also ensures accurate and repeatable settings and facilitates integration into automated processes. Combined with the innovative CIP rinsing concept, it contributes to reliable operation and high hygiene standards.
This is based on a continuously refined impeller that is designed to be durable and reliable, and to ensure a high level of process reliability. Its optimal adjustability ensures stable process control, even under varying operating conditions. A hygienic version is also available for applications requiring high levels of product safety and cleanliness. The hygienic design, along with the optimised arrangement of the rinse nozzles and housing, ensures safe operation and reliable cleaning.
