  • Overview

Features and Benefits:

  • Withstands high pressures, vacuum, and high shaft speeds for reliable sealing in demanding applications.
  • Maintains integrity through CIP and SIP cycles, reducing contamination risks and cleaning downtime.
  • Ships with short lead times, no minimum orders, and engineering support for custom designs.
  • PS-SEAL® with KF (carbon fiber) lip excels in dry-running service, extending life and reducing downtime.
  • PS-SEAL® with MS (molybdenum disulfide) lip resists abrasion in powders, slurries, and particulate media.
  • PS-SEAL® with GYLON® BLACK (graphite) lip provides reliable performance where consistent lubrication is present, ensuring durability and long service life.
  • PS-SEAL® with F (Econol) lip is optimized for vacuum service, ensuring tight sealing under low-pressure conditions.
  • PS-SEAL® with GYLON® WHITE (barium sulfate) lip ensures FDA and EN 1935 compliance for food and pharma processes.
  • PS-SEAL® with GYLON® BLUE (glass microsphere) lip offers flexibility and stability in dry-running or start-stop conditions.

Typical Applications:

  • Mixers and agitators in food and beverage processing
  • Screw conveyors handling powders, grains, or bulk solids
  • Pumps and compressors exposed to corrosive or abrasive media
  • Blenders and granulators in pharmaceutical production
  • Filling and packaging equipment requiring hygienic sealing
  • Stirring systems in chemical and biotech processes
  • Dry-running shafts in start-stop or intermittent duty equipment
  • Rotary valves and dosing systems handling viscous or sticky materials
  • High-temperature processing lines in food or specialty chemicals
