The company Chupinpack, importer and distributor for France of the BFM Fitting waterproof flexible connection sleeves, offers a new effective and clean sealing solution to be installed on all types of big-bag filling stations with chute. Indeed, filling big-bags or flexible containers without dispersing product represents a challenge for all production lines. In order to ensure efficient operations, it is therefore essential to have an inflatable cuff, which is easy to use and changes quickly. Based on its patented flexible cuff system with stainless steel tubing, BFM Fitting has developed a fully waterproof inflatable cuff to improve the filling of flexible containers with a chute, without product dispersion, and durable over time. But how does it work? The BFM sealing solution for filling the big-bag consists of an inflatable three-layer cuff, which clips easily into the BFM tubing welded to the discharge pipe. Its central part in stainless steel is encapsulated between two layers of Seeflex, resistant and flexible urethane. The BFM system is supplied with a quick coupling for the connection of a standard 8 mm pneumatic hose in order to inflate the ultra-resistant flexible outer layer. The operator places the container chute on the inflatable cuff. When the outer layer of Seeflex swells, the big-bag chute remains in the open position for the duration of filling, without risk of product leakage. When filling is complete, the outer cuff can be instantly deflated, allowing the container to be easily removed. The gains for the operator? The Seeflex material from BFM, a transparent thermoplastic urethane certified for foodstuffs, is much more resistant than the silicone-rubber of today's inflatable rings which wear out quickly. The 100% tightness of the BFM system is the most efficient on the market. In addition, thanks to the BFM attachment system, removing, cleaning and replacing the inflatable cuff is easier and faster than with traditional inflatable seals. The BFM system also provides total security for operators since there is no risk of pinching when removing the chute from the flexible container. The BFM inflatable cuff is available in the following diameters: 250 mm, 300 mm, 350 mm, 400 mm.
