Description
DAGYEE High-Speed Submersible Mixer – Intense Agitation for Rapid Mixing & Solids Suspension
A high-speed submersible mixer is a powerful mixing device designed for intense agitation, rapid blending, and effective solids suspension in wastewater treatment and industrial applications. Unlike low-speed flow generators that focus on creating circulation patterns, high-speed mixers operate at 480-980 RPM to generate strong turbulence and high shear forces. This makes them ideal for applications where rapid mixing, homogenization, or solids lifting is required.
The mixer consists of a submersible motor directly coupled to a high-speed propeller. The motor is fully sealed and rated IP68 for continuous operation under water. The propeller is designed with a self-cleaning geometry that prevents debris accumulation and maintains consistent performance.
DAGYEE high-speed submersible mixers are built to handle the toughest mixing applications in wastewater treatment. Their robust construction, reliable sealing system, and efficient hydraulic design make them the preferred choice for demanding industrial environments.
Submersible Mixers principle
The Process Flow:
Step 1: Submersion
The mixer is fully submerged in the tank and typically suspended from a guide rail system for easy installation and maintenance. The IP68-rated motor housing ensures watertight operation.
Step 2: High-Speed Rotation
The motor drives the propeller at 480-980 RPM, creating high-velocity flow and intense turbulence. The high rotational speed generates strong shear forces that break up agglomerates and promote rapid mixing.
Step 3: Flow and Mixing
The high-speed rotation creates a strong axial flow that draws liquid from the front and discharges it in a focused jet. This jet generates turbulence that ensures rapid mixing and keeps solids in suspension throughout the tank.
Step 4: Solids Suspension
The intense agitation lifts settled solids from the tank bottom and maintains them in suspension. The flow pattern is designed to prevent dead zones where solids could accumulate.
Step 5: Homogenization
The strong mixing action ensures uniform distribution of solids, chemicals, and biological materials throughout the tank volume.

This explosion-proof submersible mixer is exclusively suitable for high-risk industrial scenarios such as petrochemical plants, oil refineries, natural gas enterprises and coal chemical factories, targeting flammable, volatile and oil-containing wastewater treatment. It solves the defect of high energy consumption of traditional explosion-proof mixing equipment, equipped with high-efficiency energy-saving explosion-proof motor, which reduces invalid power consumption on the premise of meeting industrial explosion-proof safety standards. It is the only safe and energy-saving preferred stirring equipment for special dangerous sewage treatment projects, perfectly balancing safety performance and operating cost control.
Submersible Mixers Installation Method
Dagyee explosion-proof submersible mixer adopts heavy-duty full explosion-proof guide rail lifting installation system as standard. All installation accessories including guide rails, brackets, fasteners and bottom bases are made of anti-static and anti-spark special metal materials, which will not generate impact sparks during water flow impact and equipment operation. The modular lifting structure supports free underwater lifting, inspection and maintenance without draining tank water or shutting down the dangerous treatment system, ensuring continuous safe operation of the project. For special limited-space explosion-proof tanks, customized fixed anti-explosion suspension installation schemes can be provided to adapt to special tank structure requirements.
Submersible Mixers Factor
- Selection Factor: Strictly select matching explosion-proof grade and power model according to project hazard level, sewage flammability and tank volume parameters.
- Operation Factor: Prohibit frequent start-stop and overload operation, keep standard diving depth to avoid idle running and spark hidden dangers.
- Safety Factor: Regularly detect explosion-proof sealing performance and electrical isolation structure to eliminate potential safety hazards in dangerous working conditions.
- Maintenance Factor: Professional staff must conduct regular inspection, replace aging explosion-proof accessories regularly to maintain long-term safety performance.
