- Balanced / Unbalanced type spring seals
- Independent on direction of rotation
- Inherently pressure balanced
- Rigid and strong metal bellow
Welded metallic bellow seals are designed to avoid most probabilities of failure. As they do not have dynamic sealing devices like O-ring, wedges ,etc. which cause shaft grooving or fretting. Replacing springs with metal bellows ensure even loading and self cleaning to avoid clogging.Most commonly used for thermic fluid applications.
- Suitable for high temperature
