This material is produced under thename GYLON using a method deve-loped by PS-SEAL product family is manu-factured specially for the reliable sealing of rotating shafts at high peripheral speeds, pressures and tem-peratures against aggressive media. These applications were traditionallysealed with elastomeric radial shaftseals to a limited extent, if at all. PS-SEAL seals are a viable alternativeto mechanical seals and can be used on pressure and vacuum duties suitable for high peripheral speeds temperature-resistant up to +260 C excellent chemical resistance usable in the food and pharmaceutical sectors good dry-running characteristics low friction and wear-resistantThe PS-SEAL product family offerseconomic and practical solutions toa wide range of manufacturing capacityoffers everything under one roof.

In addition, the gapbetween the seal case and the shaft is the section on application limitThe GYLON lip material has temperature limits of 90 C to +260 C. The working temperature is not thesame as the operating/process temperature.

Different material combinations are available to takeaccount of varying application requirements in the che-mical, food, pharmaceuticals and engineering surfaceAttention must also be paid to the running surface,which plays a critical role in sealing integrity.

The basic concept of the PS Cartridge is the separationof the seal arrangement on the shaft from the fixed cas-ing components coupled together with a permanentresilient Cartridge floating seal assemblyThe PS Cartridge floating assembly is another designvariation of the PS used where there are large shaft run-outsin the sealing area where maintaining concentricity is aproblem and which can only be contained with specialflexible compensator units.

Never install it over sharp edges, lips andkeyways without taking proper precautions When the GYLON seal lip is installed with it s back to the shaft ( ), radii or lead-in chamfers are to be provided to the end of the shaft. All edges should berounded and the GYLON seal lip is mounted in the direction of the shaft end, a lead-in chamfer of approx. 10 isnecessary. If this is not possible for construction reasons,we recommend that a separate cone be manufacturedfo facilitate correct 2 and 3 show the lead-in chamfers and examples for designing the installation cone. The surfaces of the installation aids must be smooth and free from grooves.
