R&D Background
When the size of solid particles in the pumping medium exceeds the pump's capacity, or when long fibers or colloidal impurities are present, it becomes difficult for the pump to cut and transport these materials effectively. This can lead to sedimentation or entrapment, ultimately causing blockage. While some submersible sewage pumps have undergone mixed improvements, they often fail to address the root issue of clogging. Although their anti-blocking and overflow capabilities have been enhanced, large solid particles and long fibers still remain unprocessed, limiting the actual effectiveness of wastewater discharge.R&D Concept
The Deep Blue Group Fluid Technology Research Center continuously works on transforming technical innovations into practical solutions. As a result, the double-edged knife submersible pump was developed, specifically designed to overcome the challenges caused by large particles and fibers that traditional pumps struggle to handle.Technical Features
Compared to conventional sewage pumps, this model features a unique dual-channel cutting hydraulic system. The rotary cutter head is installed before the impeller, with fixed knives and rotating knives made from carbide material. This design allows for efficient cutting of solids and fibers, making it ideal for harsh environments with high levels of debris. The pump is compact in structure and equipped with an integrated level control switch, enabling automatic operation without the need for constant human supervision.Structural Advantages
A. Motor: Special insulation design ensures reliable performance even in minimal water conditions. B. Hydraulic Components: Utilizing advanced CFD (Computational Fluid Dynamics) technology, the hydraulic components offer high lift, full head, high efficiency, and excellent resistance to clogging and wear. These features place the pump at an international leading level and have been patented. C. Sealing Design: A unique sealing system allows the pump to operate efficiently at deep depths. D. Protection Measures: In addition to standard motor protection, the junction box cavity, motor, and oil chamber are equipped with leak detectors. The stator winding also includes an advanced protection device, ensuring safe and stable operation.Application Areas
This pump is widely used in residential sewage systems, hospitals, hotels, mining operations, municipal water supply and drainage, urban wastewater treatment plants, civil air defense drainage systems, construction sites, rural biogas systems, and irrigation projects.Performance
Before entering the impeller, all impurities in the medium are finely ground. For example, items like gloves and plastic bags are instantly shredded, allowing for smooth pumping and discharge—something no other sewage pump can match. This makes the double-edged knife submersible pump an ideal solution for challenging wastewater applications.Coffee Scale,Best Coffee Scale,Coffee Scale Accuracy,Accurate Coffee Scale
