Non Clogging Submersible Pump
Technical Core: Integrated Anti-Clogging and Slag-Crushing Design
Specially designed for conveying wastewater containing a large amount of easily entangled impurities such as fibers, cloth strips, and kitchen residues, the non clogging submersible pump adopts a combined structure of "open impeller + tearing knife" to solve the clogging problem from the source. When the non clogging submersible pump works, the high-strength tearing knife at the edge of the impeller first cuts the long fibers and large debris in the wastewater into pieces, and then the open impeller (with a wide flow channel) efficiently conveys the crushed wastewater, avoiding the winding and clogging of the impeller of traditional pumps.
Structural Design and Core Performance
The structural highlight is that the impeller is cast with wear-resistant alloy material, the hardness of the tearing knife reaches above HRC55, and the flow channel of the pump body adopts a streamlined large-opening design to reduce impurity retention. The motor is equipped with an overload protection device that automatically shuts down when locked-rotor occurs.

Core Advantages and Application Scenarios
Its biggest advantage is excellent anti-clogging performance, with a continuous operation clogging rate of ≤0.5%, and the maintenance frequency is reduced by 60% compared with ordinary submersible sewage pumps. Typical application scenarios of the non clogging submersible pump include sewage lifting in catering kitchens, kitchen waste wastewater treatment in food processing plants, sewage discharge in vegetable markets, and sewage conveyance after grilles in sewage treatment plants with high impurity content. There is no need to frequently disassemble and clean the impeller.
