Features mechanical seal type 676
- 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.
Features mechanical seal type 676
- 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.
