Progressive Cavity Screw Pump
The Progressive Cavity Screw Pump was first developed and successfully applied in Peru in the 1960s, initially used for catching fish and shrimp. In order to prevent solid substances from clogging and ensure smooth outflow, a twisted screw blade is installed in the impeller. Along the axial extension of the conical wheel hub from the suction port, the radius of the flow channel gradually increases, forming a helical flow passage. Building on the original design, advanced production techniques from leading enterprises were introduced to further improve the pump. In addition to the original belt pulley transmission method, a new shaft-coupled transmission method was developed, expanding the pump's application range. After years of market promotion, it has been widely used in industries such as papermaking, fishing, sewage treatment, gelatin processing, food processing, and chemical engineering.
