?The vertical single-screw pump is a new type of liquid conveying machine with extensive applications in many industrial fields.

?The progressive cavity pump rotor plays a crucial role in a progressive cavity pump. Its primary function is to propel or extract fluids through rotation. The following is a detailed explanation of the role of the progressive cavity pump rotor:

?Common causes of premature stator wear in screw pumps include the following:

?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:
