Submersible Mixers Description
Dagyee standard energy-saving submersible mixer is a mainstream general-purpose underwater stirring equipment developed for municipal sewage and conventional biochemical water treatment projects. It adopts mature direct-coupled integrated structure of motor and impeller, with compact overall layout and no redundant mechanical parts. The full submersible working design enables the equipment to work completely underwater without occupying ground space and avoiding external noise interference. Equipped with dual mechanical seal system and IP68 full waterproof grade, this submersible mixer supports 24-hour continuous long-cycle operation with stable sealing performance and zero water leakage. The streamlined hydrofoil impeller effectively prevents fiber winding and sludge adhesion, ensuring continuous and uniform water stirring and circulation, and solving common problems such as water stratification and sludge sedimentation in conventional sewage tanks.
Submersible Mixers principle
Component
- Motor
- Upper bearing
- Seal monitoring&indication
- Solids deflection ring
- Mechanical seal
- Axial flow propeller
- Bracket
- Control System
- Corrosion resistant shell
The operating principle centers on converting electrical energy into controlled hydrodynamic flow. The motor drives an impeller (typically a three-blade propeller or specialized mixing disc) that rotates at optimized speeds. This rotation creates a powerful axial or radial flow pattern, generating a directional current within the vessel. This current ensures complete circulation, preventing sedimentation, maintaining solids in suspension, equalizing temperature and concentration gradients, and enhancing chemical or biological reactions by ensuring uniform contact between components.

Energy-saving Submersible Mixers Selection
This standard submersible mixer is the preferred universal model for conventional municipal sewage treatment plants and general biochemical tank projects. It is suitable for non-corrosive domestic sewage water bodies with normal sludge concentration and stable water quality. It matches medium and large tank volume and conventional water depth working conditions, fully meeting the daily homogenization, circulation and anti-sedimentation needs of biochemical treatment systems. For project owners and engineering companies that pursue stable operation, low failure rate and basic energy consumption reduction, Dagyee standard mixers can effectively reduce long-term operating power consumption while ensuring sewage treatment efficiency, with extremely high cost performance.
Submersible Mixers Installation Method
Dagyee standard submersible mixer adopts stainless steel guide rail lifting installation as the standard configuration. The complete supporting system includes vertical stainless steel guide rails, high-strength lifting brackets, fixed bottom bases and anti-loosening fasteners, with firm assembly and strong water flow impact resistance. The greatest advantage of this installation method is free underwater lifting and lowering. Daily inspection, maintenance, repair and replacement can be completed without draining tank water or shutting down the water treatment system, which greatly saves later maintenance time and engineering cost. In addition, fixed suspension installation can be customized for small shallow water tanks to adapt to different tank structure requirements.
Submersible Mixers Factor
- Selection Factor: Confirm tank effective volume, water depth and sludge concentration to match reasonable power and impeller specification.
- Operation Factor: Keep standard submersible depth to avoid equipment floating, exposure and idle running failure caused by water level fluctuation.
- Maintenance Factor: Regularly check oil quality, sealing components and impeller dirt to eliminate hidden dangers and extend service life.
Submersible Mixers Features
- Excellent Energy Saving: Optimized motor and hydraulic structure reduces power consumption by more than 20% compared with traditional mixers.
- Stable & Low Failure: Integrated sealed structure, low vibration and low noise, suitable for long-term uninterrupted operation.
- Self-cleaning Performance: Streamlined impeller avoids sludge adhesion and fiber winding, reducing manual maintenance frequency.
- Strong Adaptability: IP68 waterproof and dustproof, stable operation in various conventional sewage working conditions.
Submersible Mixers Application
