Innovation in detail

Optimized bellows design

• Reduced outer diameter of seal shoulder enables direct bellows support through retaining ring or smaller spacer rings
• Optimized automatic alignment for axial shaft movements
• Minimized stick-slip effects
• Impervious to shaft deflections through high axial mobility
• Protection of shaft across the entire seal length
• Special bellows design protects the seal face during assembly

Innovative PEEK-PTFE disk

• Outstanding sliding properties and consistent centering across the entire pressure operating range
• Continuous self-cleaning of disk and shaft additionally ensures alignment of the elastomer bellows

Optimized high-performance SiC series

• Up to 50 % longer operating periods
• Extended emergency running properties
• Reduced power consumption
