The High-Performance Shaft Seal The thermoelastic high-performance seal Multi-Seal is an alternative for mechanical seals and braided packings. The thermoelastic high-performance seal TEDIMA MultiSeal operates with a seal lip of a modified PTFE material with stopped cold flow. This material is produced in a special process under the brand name ‘TEDEX’. Seal lips made of TEDEX have a considerable memory effect, high elasticity, low friction, high wearing quality and do not need a metallic spring element. TEDIMA high-performance MultiSeals are especially produced to ensure a reliable seal for rotating shafts with high pressure, high peripheral speed, high temperature, aggressive media, poor lubrication or dry running. With these applications, conventional radial shaft seal rings are not an ideal option because of the Elastomer material of their seal lips. - - MultiSeal Single lip - - - - MultSeal Double lip, back-to-back - - MultSeal Double lip, tandem Application in the food and pharmaceutical industry Both the MultiSeal Standard single and double lip are appropriate for the above sensitive application fields. Advantages of MultiSeal: • applicable with pressure and vacuum • suitable for high peripheral speed • temperature resistant up to 260°C • excellent resistance with chemical media • applicable in the sensitive food and pharmaceutical industries • wear-resistance and low friction • outstanding behaviour under dry running conditions - - Some typical applications: • centrifuges • mixing machines • compressors • agitators • pumps • rotary valves • rotary feedthroughs • screw-conveyors • separators
