Twin screw conveying pump is a positive displacement pump

It has a double - suction structure. The two ends of the screw are in the same pressure chamber, and the axial force can be self - balanced. There are two types of bearings at both ends, external and internal. The external - bearing structure adopts independent lubrication and is not affected by the conveyed medium.

The two screws are driven by a pair of synchronous gears. There is a tiny gap between the screw tooth surfaces. Except for being scoured by impurities in the medium, the screw tooth surfaces will not be directly worn.

Smooth conveying: The liquid is conveyed smoothly, with no pulsation, no agitation, low vibration and low noise, which can ensure the stability of the materials during the conveying process and reduce the impact on the materials.

Strong self - priming ability: It has a very strong self - priming performance. When multi - phase mixing and conveying, the gas content rate is not higher than 80%, and the sand content is not higher than 500g/m³, which is suitable for some conveying scenarios that require self - priming ability.

Wide application range: It can convey various non - lubricating media, low - viscosity or high - viscosity media that are clean or contain small solid particles (generally the particle diameter is less than 0.12 - 0.2mm), and by correctly selecting materials, it can even convey many corrosive media.

Reliable operation: It is driven by synchronous gears. The two rotors do not touch each other, and it is okay even if it runs idle for a short time. The shaft end adopts mechanical seal or bellows mechanical seal, which has the characteristics of long life and less leakage.

The working pressure can reach 4.0MPa; the flow range is 1 - 1000m³/h; the temperature range is - 20 - 120℃; the medium viscosity is 1 - 3000mm²/s, and it can reach 106mm²/s by reducing the rotation speed.
