Selection of screw pump in sewage engineering

Screw pumps are widely used in sewage treatment plants for transporting water, wet sludge, and flocculant solutions due to their variable conveying, self-priming, reversible, and ability to transport liquids containing solid particles. The selection of screw pumps should follow the principles of economy and efficiency. If the selection is not carefully considered, it will cause trouble for future use, management, and maintenance. Therefore, choosing a screw pump that meets the actual production needs can not only ensure smooth production but also reduce repair costs. Here are some of our experiences in applying screw pumps:
