Choosing a BFM® Connector

Title Line

Depending on what product you're processing - and what the process application is - you are going to have different requirements for the flexible connectors in your process lines.

Temperature, movement, pressure, breathability and chemical resistance are just some of the important factors that need to be considered when selecting a flexible connector.

BFM® BLUEBAND™ connectors are used in multiple industries around the world on all types of bulk handling and powder processing equipment, so it is highly likely there is a connector that's going to be the perfect solution.

This page will help guide you to the right products for your particular needs.

Explore Applications and Conditions

Title Line
BFM® connectors installed on a potato flour sifter
Sifters
The constant movement on sifters puts stress on flexible connections between equipment, and often causes problems like poor sealing, leaks and failures. 
BFM® connectors installed on a metal detector
Metal Detectors
Metal detector applications can be a challenging environment for traditional clamped connector systems because steel cannot be in near proximity to the detector.
BFM® Spigots installed on product and CIP pipes
CIP (Clean In Place)
Proper cleaning of your pipes and in-line fittings is important during CIP, and having a flexible connector that can handle the chemicals and won't leak is essential.
BFM® connector with milk powder feeding into a hopper
Pressure
If you operate under pressure, keeping your product inside your process brings all sorts of challenges usually around dust control and connector failure. 
BFM® Seeflex 040E with Vacuum
Vacuum
Processors often operate equipment under negative pressure to avoid leaking product out of machinery, but you need to ensure your connectors seal properly too. 
BFM® connector and static dissipation
Electrostatic
Static dissipative connectors like the BFM® fitting range will help reduce the chance of spark discharges occurring that can potentially ignite combustible dust explosions.
