Type 676

Low-temperature, AM350 Metal Bellows Shaft Seal for Mild Corrosive Services

The Type 676, with a rotating AM350 stainless steel bellows, is well suited for mild corrosive and abrasive applications. Available with hard faces for abrasive applications and a wide variety of secondary seals that cover a broad range of applications.

Features

  • California Residents: PROPOSITION 65 WARNING
  • Static secondary seal — available in single or dual arrangements, shaft mounted or in a cartridge; manufactured with a 45-degree tilt edge at the bellows' inside diameter to disperse stresses and maximize operating life.
  • Superior nesting ripple plate shape 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 design — rotating bellows throw off suspended particles that clog spring-type seals. This self-cleaning action eliminates the need for external flushing, filters or cyclone separators and their associated costs.
  • World-class bellows manufacture — our bellows production facility has an outstanding manufacturing process with state-of-the-art stamping, welding and testing technology.
  • The Sealol® 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.
