0.85kW Cast Iron Submersible Mixer - Efficient Mixing Solution for WWTP
The QJB0.85/8 series cast iron submersible mixer is a critical process component specifically engineered for municipal and industrial wastewater treatment plants (WWTP). Constructed from high-strength casting materials, this unit operates fully submerged. It generates powerful axial thrust and radial flow fields through impeller rotation to keep solids in suspension and ensure a highly efficient biochemical reaction environment.
Core Applications
Sludge Suspension: Prevents solid particle sedimentation in biochemical and sludge tanks
Media Homogenization: Mixes wastewater from various sources to balance water quality and pH levels
Process Support: Creates circulatory flow in anaerobic/anoxic tanks to improve denitrification efficiency
Mass Transfer: Works alongside aeration systems to increase oxygen utilization rates

Technical Advantages & Reliability
Thrust Performance: With a rated thrust of 163 N, a single unit effectively covers a mixing zone of 3-5 meters in diameter, minimizing "dead zones"
Extreme Condition Adaptability: Utilizing Class F insulation and IP68 seals, the motor maintains thermal stability even under voltage fluctuations of 380 V ± 10%
Structural Consistency: High-precision machined cast iron housing offers superior vibration resistance and heat dissipation, extending mechanical seal life
Efficiency Optimization: Operating at 740 r/min achieves an optimal balance between energy consumption and flow field intensity
Frequently Asked Questions
Q: What tank depth is suitable for this model?
A: Combined with the System I mounting bracket, it is typically suitable for tank depths of 3-5 meters.
Q: Why choose cast iron over pressed steel?
A: Cast iron provides higher mechanical strength and wear resistance, making it better suited for heavy-duty industrial wastewater containing abrasive particles.
