Project Description
- O-rings are dynamically loaded to prevent shaft damage
- Easy and trouble-free installation
- Due to large radial clearance the damage to the seal faces are avoided, in addition to the seal faces being protected by strong steel parts
- Misalignment during installation and operations is reduced due to the static springs
- Pulp and paper industry
- Chemical industry
- All clean none abrasive media
- Ahlstar UP A MS21 range of pumps
- Sulzer A, APP/APT pumps
- Sulzer SL mixers
- Metso conical refiners
- Stock pumps
