8. Non-wetted Shafts
The conveying product because of the special self-sealing design does not wet the carrying
shafts of BOERGER Rotary Lobe Pumps.
The connection between the rotors and the shafts is continuously wetted by the lubricant
liquid from the intermediate chamber and thus protected from corrosion. Even after extended
operation, an easy and trouble-free exchange of the rotors is ensured.
The self-sealing design of the entirely elastomer coated rotors prevents any contact of the
pumped liquid with the shafts. With all other rotors this is ensured by separate O-rings.
