Metal Bellow Mechanical
These Mechanical Seals are extremely useful in high temperature and other complicated services. Special welding process is used on rare materials to form highly accurate and precise Bellow hence it is expensive and used in ultimate services. These Mechanical Seals are Non-Pusher and Balanced in nature. Bellow is having self cleaning action and axial movement hence do not have dynamic elastomers which overcome several dis-advantages of Pusher Seals. These are available in double configuration & cartridge assemblies too. It finds great usage in Hydrocarbon, Pulp & Paper, Steel,Mine & Power Industries. We have very long experience in reconditioning of Metal Bellow Seals.
