Submersible Mixers Description
Dagyee high thrust low speed submersible mixer is professionally optimized for large-volume deep water tanks and high-concentration sludge sewage treatment. Different from conventional high-speed mixers, it adopts large-diameter hydrofoil impeller and high-torque low-speed motor design, converting mechanical power into powerful long-distance water flow thrust. The low-speed operation will not produce high shear force, effectively protecting activated sludge activity and ensuring stable biochemical reaction efficiency. The whole machine adopts heavy-duty integrated waterproof structure and F-class high-temperature resistant motor, with upgraded dual mechanical seals to reach IP68 deep water waterproof standard, supporting 24-hour continuous operation in high-viscosity sludge water bodies.
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 high-thrust low-speed model is the best choice for large municipal sewage plants, deep water tanks and high sludge concentration working conditions. It is suitable for scenes requiring large-range water circulation and overall water quality homogenization. Compared with matching multiple small-power mixers, a single high-thrust mixer can cover a larger stirring area, effectively reducing overall equipment power and comprehensive energy consumption. It is widely selected for denitrification tanks, aerobic tanks and large regulating tanks with high requirements for energy saving and biochemical effect stability.
Submersible Mixers Installation Method
Dagyee high thrust mixer adopts heavy-duty reinforced guide rail lifting installation. Thickened stainless steel guide rails and anti-shake brackets effectively resist strong water flow impact and prevent equipment shaking and displacement. The modular lifting structure supports free underwater maintenance without draining water or shutting down the system, greatly reducing later maintenance cost. Adjustable angle installation is optional according to tank layout to realize directional water circulation and eliminate stirring dead angles in large tanks.
Submersible Mixers Factor
- Selection Factor: Match impeller diameter and motor power according to tank area, water depth and sludge viscosity to ensure full coverage of circulating thrust.
- Operation Factor: Maintain standard diving depth to avoid insufficient thrust caused by shallow water operation.
- Safety Factor: Reinforce base fixation to resist strong water flow impact and prevent equipment displacement.
Submersible Mixers Features
- Super Wide Circulation Coverage: Large-diameter impeller forms three-dimensional water circulation without dead angles in large tanks.
- Sludge Activity Protection: Low-speed operation avoids shear damage to activated sludge to stabilize biochemical treatment effect.
- High Energy Saving Rate: Save 25%-30% energy compared with traditional high-speed mixers under the same working condition.
- Strong Overload Resistance: Adapt to high-concentration sludge operation with low failure rate and long service life.
Submersible Mixers Application
- Large municipal sewage plant anaerobic, anoxic and aeration tank water circulation and homogenization.
- High-concentration sludge storage tanks and regulating tanks anti-sedimentation treatment.
- Large-scale environmental protection water treatment projects requiring long-distance water circulation.
