The processes of the food and beverage sector increasingly require effective sealing on equipment with rotating shafts.
The critical aspects of this type of application are: guaranteeing the efficiency of operation without lubrication, allowing the sterilisation cycles foreseen by the applicable rules and regulations, and using materials compatible with food products.
Fridle Group has introduced in its range of products a complete line of lip seals in thermoplastic material especially for this sector and capable of adapting to the most demanding applications.
The materials used are certified according to FDA and EU (1935/2004) standards, and contain self-lubricating fillers with high wear resistance. The chemical inertia of the compound protects the seal through several sterilisation cycles; it is also possible to manufacture products that restrict the formation of residue on the surface of the seal itself.
The lip seal in thermoplastic materials represent the evolution of the rotary shaft seal for applications in the food and beverage industry.
If it is necessary to guarantee the absence of contaminants in the fluid being processed, the elastomer “Metal & X-Ray Detectable” solutions offered by Fridle Group allow the constant monitoring of the product throughout processing.
These types of innovative materials, certified according to FDA, 1935/2004 and USP class VI standards, have been developed as a response to the ever more rigorous requirements of the food processing sector and the pharmaceutical industry.
In fact, these materials can come into direct contact with the foodstuffs being processed and allow the efficient identification of any type of contamination from elastomer components in the sealing systems with X-ray line checks.
Fridle Group offers several types of seals made of this material: O-rings, flange gaskets, water-jet-cut flat seals, special seals manufactured with flange or sleeve turning.
