Rotary Lobe Pump basically consist of two lobe rotors which rotate synchronously inside a casing without touching each other.

The two rotors divide the rotor chamber into to several smaller rooms and move in order as: a→b→c→d.

At position a, only room Ⅰif filled with medium;

at position b, some medium is closed in room B;

at position C, some medium is also closed in room A, and at position d, room A and B are connected with room Ⅱ;

here the medium is delivered to the outlet. With this circulation, the medium (material) is delivered through the pump continuously.
Sanitary rotary lobe pump specification
Technical parameters:
As the rotors rotate, the spaces between the lobes and the casing are successively filled with fluid,

which is transported to the discharge nozzle with a fixed amount of displacement.

 The pumped fluid forms a continuous stream thanks to the tolerances between the lobes and the pump casing,

 thus ensuring an efficient pumping.

 Sanitary rotary lobe pump application
Rotor Pump is wildly used to transfer viscous media in food- processing, Cosmetics and chemical industry etc.
