The Venting Surge Hopper is designed to facilitate the flow of powdery or sticky materials that are prone to bridging, commonly used above rotary valves or bag-loading heads. Its unique angled and tapered design includes an internal partition that separates the product from the airflow, allowing powder to flow in on one side while displaced air exits from the other. This setup prevents bridging and ensures consistent material flow, essential for maintaining efficiency in processing systems.

Made from Seeflex 040E, a transparent ether-based thermoplastic polyurethane, the hopper allows operators to visually monitor product flow and quickly identify any bridging. This visibility eliminates the need for opening inspection hatches, reducing downtime. Additionally, the flexible walls of the hopper can be manually manipulated ("massaged") to easily break up any bridging, further enhancing the smooth operation of processing systems.

The Venting Surge Hopper boasts a gloss finish with a wall thickness of 0.9 mm and is constructed to be dust-tight and durable with a hardness of 90 Shore A. It can withstand temperatures from -25 to 110°C with a maximum operating pressure of 0.34 bar. Certified by the FDA, USDA, and 3A for sanitary conditions, and meeting EU and Atex standards, it is ideal for use in environments requiring stringent compliance with health and safety regulations.

Yes, the hopper is available in various diameters at the inlet and outlet to suit different system sizes, ranging from 250mm to 1,000mm at the inlet and 200mm to 350mm at the outlet, with lengths from 400mm to 1,000mm. Customization allows the hopper to be adapted to specific needs, ensuring optimal performance. It is also available with a tool release option for easy installation and removal, facilitating quick access for cleaning and maintenance without the need for specialized tools.
