Da Naiscrew pumpIt is a positive displacement pump, with the main working components consisting of a stator and a rotor. The rotor is a screw with a large lead, large tooth height, and small thread inner diameter, while the stator is an elastic sleeve with a double headed spiral. The cooperating rotor and stator form a sealed cavity that is not connected to each other. When the rotor rotates inside the stator, the sealed cavity moves axially from the suction end to the discharge end of the pump, and the medium is continuously transported from the suction end to the discharge end in the cavity.

Da Naiscrew pumpCharacteristics:

1. The spiral sealing line formed by the contact between the stator and rotor completely separates the suction chamber from the discharge chamber (pressure chamber), giving the pump a valve like blocking effect.

2. It can achieve multiphase mixed transportation of liquid, gas, and solid.

3. Compared to other forms of pumps, it has a higher suction capacity (up to 8.5 meters).

4. When the fluid flows inside the pump, the volume does not change, and there is no turbulence, agitation, or pulsation.

5. The volume cavity formed by the elastic stator can effectively reduce the wear during the transportation of media containing solid particles.

6. The viscosity of the conveying medium can reach 50000mPas, and the solid content can reach 40%.

7. The flow rate and speed are directly proportional, and the flow rate can be adjusted with the help of a speed controller.

8. It can achieve constant voltage control and anti dry operation protection.
