R&D Background
When the size of solid particles in the pumping medium is too large, 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 blockages within the pump. While some submersible sewage pumps have been improved with mixed anti-clogging measures, they still fail to fully resolve the issue of clogging and overflow. The main reason is that large solid particles and fibrous materials cannot be properly discharged, resulting in reduced efficiency and poor performance in real sewage applications.R&D Concept
The Deep Blue Group Fluid Technology Research Center continues to innovate by transforming technical achievements into practical solutions. As a result, the double-edged knife submersible pump was developed, specifically designed to address the problem of large particle and fiber discharge, which often leads to clogging in traditional systems.Technical Features
Compared to conventional sewage pumps, this model features a unique dual-channel cutting hydraulic design. A rotary cutter head is installed before the pump impeller, with fixed knives at the water inlet. Both the rotating and fixed knives are made of carbide, ensuring durability and high performance. This double-cutter submersible pump is particularly suitable for harsh environments, featuring a compact and robust structure. It also includes an integrated level control switch, allowing for automatic operation without the need for constant manual supervision.Structural Advantages
A. Motor: Special insulation design ensures reliable operation even in minimal water conditions. B. Hydraulic Components: Advanced CFD (Computational Fluid Dynamics) technology is used to optimize performance, offering high lift, full head, high efficiency, non-clogging capabilities, and excellent wear resistance. These features place the design at an international leading level and have been patented. C. Sealing Design: A unique sealing system enables deep submersion and long-term operation under extreme conditions. D. Protection Measures: In addition to standard motor protection, a leak detector is installed in the junction box cavity, as well as between the motor and oil chamber. A super-protection device is also integrated into the motor stator winding for added safety.Application Areas
This pump is widely used in residential sewage systems, hospital and hotel wastewater management, mining equipment, municipal water supply and drainage, urban sewage treatment plants, civil air defense drainage systems, construction sites, rural biogas systems, and irrigation projects.Performance Benefits
Before entering the impeller, impurities in the pumped medium are effectively crushed. For example, items like gloves and plastic bags are instantly minced, allowing for smooth pumping and discharge—something no other sewage pump can match. This makes the double-edged knife submersible pump a highly efficient and reliable solution for challenging sewage applications.Weight Scale,Body Weight Scale,Weight Scale Digital,Weight Scale Accurate
