1. The conveying liquid is stable, without pulsation, stirring, vibration and noise.

2. It has strong self absorption performance, and the air content is not higher than 80% and the sand content is not higher than 500g/m3 in multiphase mixed transportation

3. The external bearing structure adopts independent lubrication and can transport various non lubricating media.

4. The synchronous gear drive is adopted, and the two rotors do not contact each other, even if they are idling for a short time.

5. The pump body is equipped with a heating jacket, which can transport all kinds of clean or low viscosity or high viscosity media containing small solid particles (generally the particle diameter is less than 0.12-0.2mm)

6. The correct selection of materials can even transport a lot of corrosive media.

7. Double suction structure, no axial force on the rotor.

8. The shaft end adopts mechanical seal or bellows mechanical seal, featuring long service life, less leakage and wide application range.
