Type 680 Metal Bellows Seals Mechanical Seal Replacement

Type 680 Metal Bellows Seals Mechanical Seal Replacement With Factory Price

The Mechanical Seal Type 680 is the ideal seal for general-purpose applications. Its rotating Alloy-20 bellows provide corrosion resistance in a broad range of corrosive media. Its cost-effective design, combined with a reliable performance history, has made the Type 680 a standard for low-temperature applications found in the chemical, water and wastewater, pulp and paper, and utility industries.

The Type 680 Metal Bellows Seals are available with hard faces for abrasive applications and a wide range of elastomers to cover a broad range of applications.

we can provide OEM service.
We are a mechanical seal manufacturer with 25 years of production experience since 1998.

1. Mechanical Seal Application:

Medium: various solutions, aromatic, crude oil processing, hydrocarbons, chemical annual output, hot oil transmission, 

especially suitable for medium high viscosity occasions suitable for petrochemical, refining oil field exploitation, 

chemical industry, chemical fiber, gold, food, medicine, thermoelectric.

2.Technical Features:

Corrugated tube adopts bow wave, which can maximize the good tracking of pressure deformation force, 

better sealing effect, different working conditions can be used a variety of materials can be designed into 

the assembled type, easy to install the flexible graphite seal.

• 01
  
  

  Static secondary seal available in single or dual arrangements, shaft-mounted or in a cartridge.

• 02
  
  

  Manufactured with a 45-degree tilt edge at the bellows' inside diameter to disperse stresses and maximize operating life.

• 03

  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.

• 04
  
  

  Self-cleaning design — rotating bellows throw off suspended particles that clog spring-type seals. 

• 05
  
  Outstanding manufacturing process with state-of-the-art stamping, welding and testing technology.

   

• 06
  
  

  The bellows incorporate all of the design features resulting from key engineering competencies, such as metallic thin shell methodology, tribology and fluid sealing technology.
