Sanitary lobe lobe pump relies on two synchronous and counter-rotating rotors (the number of teeth is 2-4) to generate suction (vacuum degree) at the inlet during the rotation process, thereby inhaling the material to be conveyed. The two rotors divide the rotor chamber into several small spaces, and operate in the order of a→b→c→d. When running to position a, only chamber I is filled with medium; when it reaches position b, part of the medium is closed in chamber B; when it reaches position c, chamber A is also closed with medium; when it reaches position d, chambers A, B and II are closed. The chambers are connected, and the medium is transported to the discharge port. In this way, the medium (material) is transported out.
