With its unique positive displacement working principle, wide media adaptability and low maintenance characteristics, screw pumps have become an indispensable fluid transport equipment in many industries.

[0003] Chinese patent CN221347248U discloses a single screw pump that can be cleaned online. In normal operation, there is a gap between the discharge housing and the stator housing, and the stator housing is in close contact with the stator.
