Asymmetrical drum funnels
Asymmetrical drum funnels for controlled filling and emptying of drums and similar containers.
Asymmetric funnels are used primarily in the chemical, pharmaceutical, and food industries and are designed for applications with high requirements for material resistance, hygiene, and process reliability.
Manufactured from austenitic stainless steel 1.4404 (AISI 316L). This material offers high corrosion resistance to aggressive media as well as good mechanical properties and is suitable for contact with sensitive products. The asymmetrical design supports targeted material flow and facilitates largely complete emptying, thereby reducing product residues and losses.
To improve cleanability, the inner surfaces are treated using the Optimized Grind Finishing (OGF) process. The resulting surface roughness of Ra < 0.25 µm reduces particle adhesion and supports hygienic cleaning processes. In addition, the drum funnels are electropolished to further increase surface smoothness and corrosion resistance.
The design of drum funnels complies with GMP guidelines and is integrated into a quality management system in accordance with DIN EN ISO 9001:2015. High tightness and mechanical stability of the components contribute to safe operation and minimize the risk of leaks and contamination.
Depending on the respective application, the asymmetrical drum funnels can be designed with different inlet and outlet geometries, sealing systems, and other customer-specific adaptations. This allows integration into existing process plants.
Due to the choice of materials and surface treatment, the drum funnels are designed for long-term use. The reduced cleaning and maintenance requirements contribute to economical use and lower operating costs over the entire life cycle.
