Lists of materials available for Boerger Multichoppers

A fluid-filled control chamber is situated between the space and the flanged-on drive. This provides protection from any medium leaking into the bearing chamber and indicates faults in the seal.

The high-strength shafts do not come into contact with the pumped medium in Boerger Multichoppers.

The wide range of materials available allows optimum adjustment to individual needs.
