STI 1 Rubber Bellows
Mechanical seal Features:

• Machined parts
• Robust Single spring
• Non-Clogging
• Rotating face fixed, it will not fall out during installation
• Torque driven no set screws required
• Full convolute bellows , allows greater axial movement/ radial runout
• Upgraded materials to prevent corrosion and premature wear
• Seal is designed to absorb both breakout and running torque
• Designed with a drive band and drive notches that eliminate overstressing of bellows
• Friction driven by the bellows to eliminated slippage, protecting the shaft and sleeve from wear and scoring
• Self-Aligning Capability compensates for abnormal shaft end play, axial and radial runout
• Special pressure Balanced, allowing the seals to handle higher pressures.
• All sizes are available.
  
  

• Superior Bellows Design
  These seals are manufactured with a 45 º tilt edge at the bellows inside diameter to disperse stresses and maximize operating life.

• Superior Plate Design
  The plate design used by STI is called a nesting bellow. With a three-sweep radius, this plate design allows the bellows device to be flexed repeatedly without the metal being stressed beyond its endurance limit.

• Self-Cleaning and non clogging Design
  Rotating bellows will throw off suspended solids preventing clogging. This self-cleaning action eliminates the need for external flushing, filters or cyclone separators and their associated costs.

• Superior class Bellows Manufacture
  Our bellows production facility has an outstanding manufacturing process with state-of-the-art stamping, welding and testing technology.

• Application Flexibility in all conditions
  A wide range of metallurgies, face combinations and packing materials are used to seal a variety of demanding applications.

• Extensive Research and Development
  The STI bellows incorporate all of the design features resulting from key engineering competencies, such as metallic thin shell methodology, tribology and fluid sealing technology, and thin film/fluid mechanics.
