Operation Principle:
Rotor pump is also named colloid 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 | is filled with
medium, when it revolves to position b, housing B encloses medium, and finally
it goes to position d, then housing A,B and || are interlinked and the  medium is
transported to the outlet. As this process is repeated, medium (material) is
transported continuously. 
 
Special Structure
Butterfly rotor pump: with butterfly rotor, it is superior to other rotor pump when transferring material with high viscosity and larger powder and effectively transports extremely stiff material.
Singe butterfly curved rotor pump (powder rotor pump): this pump series are specially design to transport material with larger powder. Its unique shape and curve makes it more outstanding compared to other pumps in delivering material with larger powders. It effectively prevents powders from clashing, which is the top choice of pumps transferring material with powders.
Widely used to deliver: various special material, stiff material, mixture with different specific gravity, corrosive material and material with larger power.Capacity / per centum rotate, range speed, corresponding discharge
