1. screw pump performance advantages:

1) Good inhalation performance, good self-priming ability;

2) The flow is continuous and uniform, the noise is low, and the vibration is small;

3) High speed can be used because the inertial force of the rotating parts in the pump is low;

4) Wide pressure and flow range;

5) The structure is solid and easy to install and maintain;

6)Less sensitive to incoming gases and dirt than other rotary pumps.

2. Screw pump performance shortcomings

1) The performance of the pump is sensitive to changes in the viscosity of the liquid;

2) Screw pump processing and assembly requirements are high.
