Rotor pump also named rotary lobe pump, three 一 lobe pump , sole pump, etc .When the 2 slmultaneous reverse rotatlng rotors ( wlth2-
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 l
is fllled with medium, when it revolves to position b , housing B encloses pert of the medium , When it goes to posiltion
c, housing. A encloses medium, and finally it goes to position d , then housing A、B and ll are interlinked and the medium is
transported to the outlet . As this process is repeated , medlum(material)is transpor-ted continuously.
