The selection of single screw pumps is mainly concentrated in the following parameters:

1. The pressure of the single screw pump is determined:

The maximum output pressure of the single screw pump is determined based on the number of guides of the band -level, that is, the guidance of the band (stator):

Level 1: The highest work pressure is 0.6 mPa;

Level 2: The highest work pressure is 1.2 MPA;

Level 4: The highest work pressure is 2.4 MPA;

Due to the different conditions of the conveying medium, for the medium that contains severe wear, select the appropriate stator level according to the requirements of the conveying pressure.
