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.
• 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.
