Inflatable seals are designed to provide efficient hermetic sealing solutions providing protection against incursions by powders, granules, gases, liquids, and dust.
These pneumatic airtight seals are extremely useful for sealing fabricated pieces of equipment where:
· the sealing gap might vary
· assembly and dis-assembly needs to be quick and simple
· hygienic procedures exist (FDA applications and regulations)
Generally working from within a specific groove size the seals can operate axially, and for both inward and outward radial movements. The most popular requirements are for FDA approved Silicone Elastomer in either Blue, White or Red iron oxide colours. Other Elastomers and Pigmentations are available for a wide variety of sealing applications.
Bond most types of the available inflation connectors to the seals as required by the customer/application. This process bonds the connector to the seal by localized injection of identical compound vulcanizing the connector to the seal. The strength of Vulcanized Connector far exceeds any mechanical fixing or adhesively bonded connector, associated with this type of seal. Inflatable Seal Manufacturer has independently pressure tested and supplied with a supporting ‘Test Certificate’.
These tests on free-standing, unsupported seals vary from 1 bar to 4 bar pressure, dependent on the profile type and/or customer specification. With the aid of purpose designed test rigs, which enclose the seal, our production techniques are tested and supported with the proven case history.
