  • Product Details

The single screw pump belongs to the rotor type positive displacement pump. The rotor and the stator driven by the external power source are engaged to form a sealed cavity that separates the suction chamber and the discharge body. The volume change in the sealed cavity is generated by the mutual meshing of the rotor and the stator to transport materials.

 

Which medium is suitable for single screw pump?

1.   High solid content (up to 45% in sewage);  

2.  Various viscosity (up to 1000000mPa.s);

3. Materials containing solid particles;

4. Media that are highly shear sensitive or susceptible to centrifugal force;    It also contains a multi-phase mixture of gas, solid and liquid.

 

Characteristics of single screw pump

1. High pump efficiency, energy saving and consumption reduction;    The volumetric efficiency can reach more than 95%;

2.  The mechanical efficiency can reach 65~85%;

3. There is no pulse in conveying, realizing uninterrupted conveying; 

4. Small mechanical vibration and low noise during operation;

5. The flow rate is strictly proportional to the rotational speed, which is suitable for metering;

6. It has little effect on the shearing property of the conveying medium;

7. Insensitive to conveying medium containing gas and solid particles;

8. Strong self-priming ability, the suction height can reach 5 meters;

9. Changing the installation position does not affect the pump work,

10. It can be installed at multiple angles.
