Optimize Your Production Process with BFM Fittings

Designed for the toughest conditions

Industrial processes place high demands on flexible connections: vibration, pressure differences, vacuum, high temperatures, and chemical cleaning. The BFM fitting performs reliably under all these conditions. Whether it’s CIP cleaning, vacuum systems, or explosion-risk environments, the unique design holds firm and prevents leakage, downtime, and failures.

Applications across all industries

BFM fittings are used worldwide in the food, feed, pharmaceutical, chemical, and mineral industries. Typical applications include:

• Sieves, vibrating pipes, and mixers where constant movement challenges traditional seals.
• Metal detectors and conveyors where metal-clamp systems often cause disruptions.
• Silos, big bag filling stations, and rotary valves where dust-free operation is critical during filling and discharge of powders or granules.

For modular clamp or piping systems

This adapter makes the connection between a BFM system and modular piping systems effortless. The 6 mm raised lip ensures the fitting can be quickly and securely fastened with a clamp, without welding. Perfectly compatible with JACOB and similar brands. This allows easy integration of BFM fittings into existing production lines and saves installation time.

Perfect connection to the Surge Hopper

This adapter is specially designed for the Surge Hopper and features a unique flange with an internally welded weir plate. This allows product to flow smoothly down one side while air is vented in a controlled manner on the other side. Ideal for preventing bridging. The adapter is available in stainless steel T304L or T316L, suitable for intensive applications above or below dosing gates. The precise design ensures the connection remains secure and leak-free.

Enhanced safety for Tool Release sleeves

The TR Lock-Out increases the safety of removing Tool Release sleeves. By placing a small tube over the TR opening, into which a padlock can be inserted, only employees with a key or code can remove the sleeve. This allows controlled and safe maintenance and prevents staff from inserting other tools into the TR opening.

Flexible, lightweight, and ATEX-safe

Flexi sleeves feature an integrated stainless steel coil. They are designed for applications where compression and movement are important, such as bulk bag fillers, filling machines, and bag feeders. Flexi sleeves retain their shape, are mechanically strong, and suitable for both horizontal and vertical movements. Available in standard, lightweight (Flexi-Light), and grounded (Flexi-Earthed) versions for extra flexibility and safety in ATEX environments.

Lightweight, breathable, and antistatic

LM sleeves are lightweight, breathable, and antistatic fittings suitable for low-pressure applications and processes requiring airflow or ventilation. LM3 is flexible and breathable, LM4 is heavier and tear-resistant for intensive industrial conditions. Ideal for minerals, powders, and ATEX-sensitive applications.

Heat- and chemical-resistant

Teflex sleeves are made from heat- and chemical-resistant PTFE (Teflon). They withstand high temperatures, aggressive chemicals, and demanding process conditions. Available in black, opaque, and woven versions, ideal for chemical processes, sterile environments, and high-temperature applications.

Safe changeover with minimal risks

Most BFM fittings can be removed without tools, but in installations near rotating or moving parts, this poses risks. The Tool Release (TR) version has a reinforced snap ring that makes manual removal nearly impossible. Only the special TR Tool allows the fitting to be safely removed. This extra protection prevents accidents and complies with Article 7.7 of the Working Conditions Decree. The TR version is ideal for applications near rotary valves, blades, or other fast-moving components.

Perfect fit between different diameters

The conical version ensures optimal connection between different diameters or transition points. The tapered design creates a strong, leak-free connection and prevents product from sticking between fittings. This makes the fitting ideal for discharge points, silo outlets, and transport transitions. The flexibility and durability of the BFM sleeve remain fully intact.

Prevents collapsing under pressure or vacuum

Anti Collapse sleeves feature internal support rings that prevent collapsing or deformation. This is essential for applications under negative pressure or heavy compression, such as silo outlets or transport tubes. The design ensures the sleeve always remains open and provides a stable, leak-free connection. Available with SS (stainless steel) or plastic support rings, depending on application and process conditions.

For CIP processes and frequent cleaning

The Wash Sleeve version is specifically designed for processes with frequent cleaning, such as CIP systems. The material resists cleaning chemicals and prevents leaks during cleaning. The smooth interior makes flushing product residues easy, ensuring a hygienic, safe, and efficient connection in food and pharmaceutical processes. Identified by the light blue “Wash Sleeve” stamp on the sleeve.

Inspection and sampling without removing the sleeve

The Quick Access Port version allows easy access to the product flow or process point. Ideal for inspections, sampling, or maintenance without dismantling the entire system. The system remains fully leak-proof and safe during use, saving time and minimizing production downtime.

Flexible solution for corners, bends, and tight spaces

Corner Connectors are designed for applications where the product flow must follow a 90° angle. Available in 040E and 060ES for light to heavy-duty applications. They ensure smooth, leak-free passage and reduce product buildup in bends or transitions. Thanks to the flexible and durable material, the fitting maintains the same hygiene and reliability as straight sleeves.

Safe and hygienic product collection

Blanking bins are designed to capture bulk products in a controlled, clean manner during transport, transfer, or maintenance. They fit perfectly to the system, preventing spills, product loss, and contamination. The flexible design ensures stability even with vibrating or moving equipment, keeping your work environment safe, hygienic, and efficient—even during temporary process interruptions.

Control over airflows

Brather bags allow controlled release of air and gas from your system without letting product particles escape. Ideal for silos, big bags, or overflow points where pressure differences occur. The strong, flexible material ensures reliable performance under heavy use, limiting dust, protecting staff, and maintaining production stability.

UV and heat protection with covers

Kevlar and Black Out covers provide extra protection for BFM sleeves. Kevlar is strong and wear-resistant, protecting against mechanical damage, heat, and sharp products. Black Out blocks light and UV radiation, ideal for light-sensitive powders and granules. Using covers extends sleeve life and ensures optimal product quality during transport and processing.

The solution against product build-up

The Surge Hopper is an innovative replacement for traditional steel hoppers. Its conical shape and central divider allow product to flow on one side while air escapes on the other. Transparent Seeflex 040E material provides full visibility of the product flow and makes bridging easy to monitor. Flexible walls facilitate clearing product buildup, and the hopper is easy to remove and clean, ensuring efficient and hygienic handling.

Accurate weighing and precise measurements

The Weighing Bellow provides a flexible, airtight connection between weighing systems and process equipment. Its elastic, wear-resistant material ensures accurate weighing even under vibration or movement. The smooth seal prevents leaks and guarantees hygienic handling of powders or granules, ensuring reliable measurements and consistent product quality.

Fast big bag filling without leaks or contamination

The BFM Bulk Bag Loader is designed for quick and safe filling of big bags without product loss or leakage. The inflatable sleeve ensures a perfect connection and can be installed or removed without tools. The Bulk Bag Loader is foodgrade and ATEX-certified, suitable for both the food industry and explosive environments.

Extra control and security for your process

Pneumatic Monitoring System: continuously monitors air pressure in the BFM system and immediately detects deviations that could affect sealing or product flow, preventing downtime and product loss.

Tool Release Tools: available in standard and Smiley versions for fast and safe TR sleeve replacement, minimizing downtime and maximizing system reliability.
