The transportation of liquid finished.

1. Steady delivery without pulsation, little vibration and noise.
2. Out standing self-priming ability.
3. The pump can deliver the varied corrosion mediums if the proper material of parts selected in addition, the working temperature can reach 200 deg C.
4. The same rotary direction of internal rotor and outside rotor results in little wear and long operation life.
5. The pump's flow can be changed through adjusting the speed.
6. It's specially suited to deliver high viscosity medium.
