The heart of the machine is made up of two lobe rotors mounted on parallel axes. They rotate in a synchronized manner inversely to each other, inside a proofed chamber. The rotors have three or four lobes, according to the pump size. The combination of the rotor movements creates suction and delivery, and the special helicoidal shape of the lobes guarantees greater fluid movement without any vibrations.
The important characteristics of this type of pump are:
Easy cleaning and maintenance (Rotors can be replaced without having to dismantle the piping)
Double rotation: the suction connection can be positioned on the right or on the left
