1) The inlet and outlet civility adopts special design to make sure that enough medium is remained in the pump. Even when the medium in the suction pipe is all discharged, the pump still has very good self-suction performance.

2) The pump body adopts special-structure circular valve, which will open when the outlet pressure is higher than the working pressure. Then, some medium will back to the inlet of pump or saving can through this circular valve. Meanwhile, the pump can starts under full pressure situation thus greatly reduce the torque.

3) Use synchronous gear to transfer toque from initiative screw to idler screw, which ensures no metal contact and power transmission between transferring elements. So the transferring elements have high reliability for any medium and the pump can free from damage of dry rotation in a short time.

4) When the pump is working, the meshing screws form a sealed civility in the pump body, following the rotary motion of the screws, the liquid in the sealed civility does axial motion with the sealed civility and transferred to the outlet of pump steadily and continuously. Because the capacity of the sealed civility never changes in the working pump, there will be no pulsation when the pump deliveries liquid.

5) The body of twin screw pump has several different heating structure plans for choice, to adapt to different medium under different temperature.

6)Outboard bearing structure which adopt independently lubricate, so all kinds of non lubricate medium can be transported.

7)The pump body has heating jacket, so it can transport all kinds of clean or low viscosity or high viscosity medium which contain the particulate solids. (the diameter of the particulate is usually less than 0.12-0.2mm)

8)If selecting the material correctly, some corrosive medium can be transported.

9)Double suction structure, and there is no axial force on the rotor.
