Rotor pump is also named rotary lobe pump,three-lobe pump,sole pump,ect.When the 2 simultaneous reverse rotating rotors(with 2-4 gears)revolve,it produces suction force at the inlet (vacuum),which intakes the material delivered.The 2 rotors divid the rotor housing into many smaller parts and revolve in the sequence of a-b-c-d.When is revoles to position only housing I is filled with material .When revolves to position b,housing B encloses part of the me medium.When it goese position c,housing A encloses medium,and finally it goes to position d,then housing A,B and II are interlinked and the medium is transport to outlet.As this process is repeated,medium (material) is transport continuously.
