2W W-sealed twin screw pump

2W The W-sealed twin screw pump forms sealed cavities in the pump body through the meshing of the main and driven screws in the pump body, as well as the matching of the screw and the pump body hole. When the screw rotates, these sealed cavities continuously move forward, pushing the liquid in the sealed cavity to be discharged from the outlet, achieving the purpose of pumping liquid

2W Advantages of W-sealed twin-screw pump:

1. The twin-screw pump can transport liquids smoothly, without pulsation, stirring, vibration, and noise

2. Twin screw pumps have strong self suction performance. When transporting multiphase mixtures, the gas content is not higher than 80%, and the sand content is not higher than 500g/m3.

3. The external bearing structure of the twin screw pump adopts independent lubrication, which can transport various non lubricating media.

4. The twin-screw pump is driven by synchronous gears, and there is no contact between the two rotors, even if it runs idle for a short time

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

6. The correct material selection for twin-screw pumps can even transport many corrosive media.

7. The double suction structure of the twin-screw pump has no axial force on the rotor8. The shaft end of the twin-screw pump adopts mechanical seal or corrugated pipe mechanical seal, which has the characteristics of long service life, low leakage, and wide applicability2W Performance range of W-sealed twin-screw pump:

1. High working pressure 4.0MPa

2. Flow range of twin-screw pump: 1-1000m3/h

3. Temperature range of twin-screw pump: -20-120 ℃

4. Medium viscosity of twin-screw pump: 1-3000mm2/s, reducing speed can reach 106mm2/s

Medium viscosity has a significant impact on twin-screw pump performance, and the nominal displacement of the pump refers to the displacement under specific viscosity conditions, To protect the pump from working at a higher efficiency during insufficient testing
