Operation Principle

Rotor pump is also named rotary lobe pump,three-lobe pump,sole pump,etc.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 divide the rotor housing into many smaller parts and revolve in the sequence of  A→B→C→D.When it revolves to position A,only housing I is filled  with medium;when it  revolves to position B,housing B encloses part of the medium,when it goes to 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 transported to the outlet.As this process is repeated, medium(material)is transported continuously.
