The materials commonly used for the stator of a single-screw pump include rubber, elastomers, and synthetic resins. The choice of these materials depends primarily on the pump's application, the nature of the conveying medium, and the required wear resistance, corrosion resistance, and elasticity.
Compared to ordinary screw pumps, single-stage screw pumps have some special structural features. These features are primarily designed to meet the unique requirements of the dosing process. The following are some of the special structural features of single-stage screw pumps:
