Your benefits
For high pressures and speeds
The tried-and-tested ROTOSTAT E sealing system uses a hydrostatically controlled radial gap seal, ensuring reliable operation even under the most demanding operating conditions.
Extremely long service life
The contactless sealing system has very low friction, reducing wear to the minimum. Cost savings are considerable.
Continuous development
The product specialists at GAT are continuously striving for further development of this high-tech product. For example, leakage could be reduced significantly by an enhanced bearing system and improved production processes introduced in 2015.
