BFM® venting surge hopper

Description:

A partitioned, transparent hopper that provides airflow to prevent bridging while allowing full product flow visibility and access.

Documents and Resources:

For in-depth information on the features and installation of Venting Surge Hopper, refer to our detailed documents and resources.

The Venting Surge Hopper is an angled, tapered connector with an internal partition that allows powder to flow in on one side and displaced air to flow up and out the other.


Unlike steel hoppers where you have to open an inspection hatch to see if bridging is occurring inside, the transparency of the Seeflex 040E material gives visibility of product flow.  Its flexible walls are malleable, meaning bridging can often be easily freed up simply by massaging the side of the hopper.


The hopper is designed to fit into a special Surge Hopper Spigot (on the lower end) that features a weir plate to match the angle of the connector partition. 


Application

  • As an intermediary hopper above a rotary valve or bag-loading head.

Frequently Asked Questions

  • What is the primary function of the Venting Surge Hopper, and how does its design support this?

    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.

  • How does the transparency and flexibility of the Venting Surge Hopper improve operational efficiency?

    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.

  • What are the key physical properties and compliance certifications of the Venting Surge Hopper?

    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.

  • Can the Venting Surge Hopper be customized to fit different industrial setups?

    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.
