With around 250 locations and 90 serve centers, we are represented in the most important economic regions of the world. The advantages are clear: short paths to our customers, fast response times and a shared language.
Small outer diameter of bellows support (dbmin) enables direct retaining ring support, or smaller spacer rings
Optimal alignment characteristic through self-cleaning of disk/shaft
Improved centering across entire pressure operating range
No torsion on bellows
Shaft protection over entire seal length
Protection of seal face during installation due to special bellows design
Insensitive to shaft deflections due to large axial movement ability
Suitable for low-end sterile applications
