Vulcan Multi-Spring Seals

Introduction Vulcan Multi-Spring Seals

Vulcan’s extensive 16XX range of Multi-Sprung Seals are commonly specified for arduous applications, such as corrosive process fluids or demanding operating parameters. The standard designs are available with a chemically resistant PTFE wedge component, which is spring loaded to force the flexible angular lip of the wedge into tight contact with the shaft.

The same spring force impacts a sufficient load to the rotary face to create a suitable seal interface with a varied choice of standard stationary seats, most commonly our Type 25 V Seat. Balanced face designs are also available for higher duty applications. ‘O’-Ring variants, of both balanced and nonbalanced Types, are available as standard. All the seal faces and wedges interchange with most common competitor designs by fitting into their retainers.

Applications

The 16XX family range are ideally suited for corrosive duties and are commonly utilised in the chemical industry, due to the inertness and sealing nature of the wedge design. These seals are also very suitable for a wide spectrum of application conditions. Their operating suitability range is enhanced by the ‘O’-Ring alternative design and the wide range of available elastomers.
