Lists of materials available for Boerger Rotary Lobe Pumps

The timing gear of a Boerger Rotary Lobe Pump is protected as it is safely separated from the pump chamber by the intermediate chamber with quench.
The high-strength shafts do not come into contact with the pumped medium in Boerger pumps.
The variety of material allows optimum adjustment to individual needs.
