The Characteristics And Application Fields Of The Spiral Lobe Rotary Lobe Pump

The spiral rotary lobe pump is a self-priming volumetric pump. It has the following characteristics.

1、No need to manually fill the pump, that is, has a strong self-priming force, the maximum suction range 8.5m; conveying flow range 1-2000m/h.

2. The maximum medium viscosity is 100,000 cp and the maximum solids content is 60% of the slurry.

3. Forward and reverse rotation is possible, suitable for loading and discharging scenarios, as well as for sewage treatment areas where backwashing of the filter membrane is required.

4、The non-clogging design ensures the passage of large diameter materials, with a maximum passage diameter of 80mm.

5、Triple flow precision casting mould and five-axis linkage process empowered with the pump, making it highly efficient, energy saving and low noise.

6. The double support structure allows the pump to run more stably and the output pressure can be up to 1.8Mpa.

7、Smooth conveying, small pulsation, low shear force, can convey mixed media of gas, solid and liquid as well as media sensitive to cut-off, such as liquid bombs.

8、Back cover extraction design, no need to disassemble the pump body and pipeline for maintenance

9. Low speed of 10-650r/min, wear-resistant rubber liner with axial and radial wear plates for longer pump operation and low failure rate.

10、For different working conditions, special devices such as safety valves, heat preservation and cooling can be configured to achieve different working condition requirements.

11、Configuration of reducer to adjust the motor speed, so as to achieve the purpose of adjusting the flow.

12、The application range of the rotary lobe pump is extremely wide and applicable, different materials and different rotors can be used according to different working conditions.
