1.Flow and speed are in direct proportion, automatic flow adjustment can be achieved by speed controller.

2.Various shaft sealing options can be realized due to composite design of sealing chamber

3.Opposite direction transfer in short term can be realized due to composite design of the flange and bearing.

4.Various stator and rotor material pairing for various working conditions.

5.Stable flow and pressure, no pulsation, low noise and strong self-priming ability.

6.Wide application scope for various fluid medium, including high viscosity, solid content, fiber, suspended impurities.

7.Use oil instead of traditional grease for bearing to enable more sufficient and effective bearing lubrication


Indications for type selection:

1.Attentions should paid to pump inlet flow velocity (including inlet pipeline velocity). Normally the inlet velocity should be controlled within 1m/s ,1-1.3m/s can be selected conditionally,velocity larger than 1.3m/s shall be selected cautiously or never;

2.With the medium viscosity increasing,it will become more difficult for the medium to enter into the sealing chamber and the mechanical loss will also increase.Therefore,We recommend the larger viscosity and the lower vgm value as following table.


Performance: Flow 180 m3/h

Maximum Pressure:2.4 Mpa

Maximum Temperature:220 ℃
