2W.W Sealed twin - screw pump

2W.W sealed double screw pump adopts double suction structure. Both ends of screw are in the same pressure chamber, and the force of shaft can be balanced by itself.At the ends of the bearing installed in place of the type, lubricated by lubricating oil (grease) alone, with a pair of synchronization between the two screw does not contact between gear drive screw tooth surface, and leave a small gap, the impurities in medium can not be directly on the screw tooth surface wear.There are two ways of import: first, horizontal in, horizontal out;The second is going in horizontally and out vertically.Users can make their own choices according to their needs.

2W. Advantages of w-sealed double-screw pump:

1. Stable, pulsating, non-stirring, low vibration and low noise.

2. Strong self-absorption performance. When mixed transportation of multiphase, the gas-bearing rate is no more than 80%, and the sand content is no more than 500g/m3.

3. External bearing structure, independently lubricated, can transport various non-lubricating media.

4. Adopt synchronous gear drive, no contact between the two rotors, even a short time of idling is ok.

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

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

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

8. The shaft end adopts mechanical seal or corrugated pipe mechanical seal, with features of long life, less leakage and wide application range.

2W. Performance range of w-sealed double-screw pump:

1. Working pressure: 4.0mpa

2. Flow range: 1 ~ 1000m3/h

3-20 ~ 120 ℃, temperature range

4. The viscosity of the medium is 1 ~ 3000mm2/s, and the reduced speed can reach 106mm2/s

Medium viscosity influence the performance of double screw pump, pump displacement refers to the specific viscosity of conditions in the name of the displacement, in order to ensure the pump can work in high efficiency, when the test is not sufficient, suggestion choice speed on the viscosity of the following terms and conditions:

Medium viscosity cSt speed r/min

< 400 1500

400 ~ 1200, 1000

1200 ~ 3600, 750

For a more viscous medium, the speed and power of the drive motor should be selected, please contact the manufacturer.
