Operating under pressure can be problematic

Title Line

For process lines operating under pressure, keeping product inside the process poses various challenges, especially around dust control and connector failure.

Old-style connectors, particularly clamp bands, are prone to failure as pressure within the sleeve increases. They are also prone to continuously leaking product which creates a messy and unhygienic environment.

What's the solution? BFM® fitting, the only flexible connector system that is installed on the inside of the pipe, can prevent product leaking at transition points in the machinery.

BFM® fitting performs better under pressure

Title Line

BFM® fittings are probably the most pressure resistant form of flexible connection available in the world.

The BFM® connector’s internal seal is proven to withstand far higher pressures than clamped connectors without leakage. In fact, our patented spigot and snap-in blue band connector system mean any internal pressure just pushes the cuff of the connector harder against the walls of the spigot, creating an even tighter seal.  

There is nowhere for product to leak or build-up as there are no crevices on the outside of the pipe for it to escape to.   

Our Seeflex 040E connectors have been pressure tested to safely perform under constant pressures of up to 5PSI (34.5kPa,  .345Bar), and explosion pressures of over 9.14PSI (63kPa, .63Bar).

Advantages of BFM® fitting with Pressure

Title Line

The BFM® fitting flexible connector system is made with high-quality materials designed to minimize connector failure that can occur due to overpressure situations.

The BFM® fitting design is, 100% dust-tight, eliminating product leakage. The seal becomes tighter when there is more pressure in the system. 

Proven to contain initial explosions, BFM® fittings also help eliminate dust leakage into the plant, reducing the risk of secondary explosions. 

Superior materials, like our unique Seeflex urethane, and pressure-resistant design mean BFM® connectors are stronger and last much longer.

Our wide range of products have been independently tested to conform to important global standards like ATEX, 3A, USDA, FDA &  EC.

Explore more Applications and Conditions using BFM® fitting

Title Line

BFM® fitting outperform traditional hose clamp systems in virtually every processing application and condition. Here are some common process applications that are challenging for flexible connectors:

BFM® connectors installed on a metal detector

Metal Detector applications can be a challenging environment for traditional clamped connector systems because steel cannot be in near proximity to the detector.

See why BFM® is used with metal detectors.

BFM® Seeflex 040E with Vacuum

If you operate equipment under negative pressure to avoid leaking product out of machinery, you must ensure your connectors seal properly to ensure efficiency.

Find out why BFM® is ideal for vacuum.

BFM® Spigots installed on product and CIP pipes

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.

Watch a BFM® fitting in action during CIP.

BFM® connector and static dissipation

Static dissipative connectors like those in the BFM® fitting range will help reduce the chance of spark discharges occurring that can potentially ignite combustible dust explosions.

The constant movement of sifters and sieves puts stress on flexible connections between equipment, and often causes problems like poor sealing, leaks and failures.

Pressure Resistant Seeflex 060ES

Title Line

Our high-pressure resistant Seeflex 060ES connector can operate comfortably up to 24PSI* (170kPa, 1.7Bar) of continuous pressure.

The secret to the success of the product is in its make-up: a polyester scrim is internally bonded between layers of Seeflex (an ether-based polyurethane).

The polyester scrim restricts the Seeflex and stops it from expanding, providing superior pressure resistance and can be used in all food-contact applications.

How BFM® created a dust-free work environment that is "a pleasure to work in"

Title Line

A leading New Zealand dairy plant had a major challenge with hygiene in their blending filler room. A vibratory discharging cone was connected to the hopper via a traditional connecting sock and steel clamps.

Regular gas purging of the system forced powder through small gaps in the old-style sock and steel clamp connector. There was excessive dust leakage and product build-up in the joins – a major hygiene issue.

Since installing the BFM® fitting system, the room is clean and there has been a significant reduction in both downtime and replacement costs.
