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.
Deformation-optimized seal for high pressures and high sliding velocities
Economical due to standardized inner components
High flexibility due to adaptation of the connection parts to the pump seal chamber
Insensitive to shaft deflections due to stationary design
Dual seal does not open even in the event of barrier fluid pressure failure
Reliable operation due to one rugged seat with bandage
Version with loose-fitted seal face available, for extreme applications
Only small number of components
