Suitable for pressure reversals
Operation in vacuum without additional seat locking possible;
No damage of the shaft by a dynamically loaded O-Ring;
Small installation sizes
Best suitable for conversions, no adaptations of the pump;
Insensitive to solid containing and abrasive media
Advantages of a balanced seal even with plain shafts
Insensitive to shaft movements because of the stationary design
