1) Wide range of pressure and flow. The pressure is about 3.4-340 kgf / cm 2, the flow rate is up to 18,600 cm 3 / min;
2) Wide range of liquid types and viscosities;
3) Because of the lower inertial force of rotating components in the pump, it can use high speed;
4) Inhalation performance, self-priming capability;
5) uniform and continuous flow, small vibration, low noise;
6) less sensitive to incoming gas and dirt compared to other rotary pumps;
7) solid structure, easy installation and maintenance.
The disadvantage of the screw pump is that the screw machining and assembly requirements are higher; the performance of the pump is sensitive to changes in the viscosity of the liquid.
