WWTP 368r/Min Cast Iron Submersible Mixer IP68 790mm
The 790mm large-diameter cast iron submersible mixer series is a heavy-duty agitation solution specifically engineered for large-scale municipal Wastewater Treatment Plants (WWTP) and industrial biochemical tanks. Constructed with a high-strength cast iron housing, it offers exceptional vibration resistance and thermal dissipation. The core advantage lies in combining a 368 r/min low-to-medium speed with a 790mm large-diameter impeller to generate high axial thrust at low energy consumption, making it ideal for preventing sludge accumulation and enhancing flow circulation.
Core Applications
Large-Scale Tank Propulsion: Drives large volumes of water in aeration, anaerobic, and anoxic tanks to keep activated sludge in suspension.
Low-Speed Flow Assistance: Provides continuous and stable flow field dynamics for deep or high-capacity tanks.
Sludge Homogenization: Ensures uniform mixing of high-concentration media in sludge digestion or storage tanks.
Mass Transfer Improvement: Optimizes hydraulic circulation paths to enhance the uniformity of dissolved oxygen distribution.

Technical Advantages & Reliability
Exceptional Thrust Output: With a rated thrust of 3540N, a single unit can establish a powerful circulation flow in large tanks, with a coverage radius significantly exceeding conventional mixers.
Heavy-Duty Structural Consistency: The 270kg cast iron body provides immense structural rigidity, effectively counteracting mechanical vibrations from the large impeller and protecting the mechanical seals.
Extreme Environment Durability: Utilizing IP68 multi-stage sealing and Class F insulation ensures the motor maintains thermal stability during long-term submersion and continuous heavy-load operation.
Energy-Efficient Flow Design: The optimized hydraulics of the 790mm impeller minimize energy loss while maintaining high thrust, helping WWTPs reduce operational electricity costs.
Frequently Asked Questions
Q: Why is the speed of this model set at 368 r/min?
A: For large volumes of water, a low-speed, large-diameter impeller offers higher hydraulic efficiency and greater thrust than high-speed, small-diameter alternatives.
Q: Does this model require special mounting hardware?
A: Due to the 3540N thrust and significant weight, it must be used with System II or System III heavy-duty mounting brackets to ensure operational stability.
