Lobe pumps are used for delivering highly viscous and highly abrasive media. In a lobe pump two non-contact pistons rotate in two cylindrical chambers. In contrast to rotodynamic pumps, a positive displacement pump moves the medium by means of closed conveying chambers. With each revolution, they deliver the same volume.
