Product Description
QJB SUBMERSIBLE MIXER & LOW-SPEED FLOW PROPELLER
Efficient Mixing, Sludge Suspension and Process-Tank Circulation
The QJB Series provides dependable mixing and circulation solutions for wastewater treatment plants, industrial process tanks and biological treatment systems.
Two main configurations are available:
Mixing Series
Designed for rapid and uniform mixing of liquids containing suspended solids. It helps prevent sedimentation, maintains solids in suspension and improves process consistency.
Low-Speed Flow Propeller Series
Designed to generate high-volume, low-velocity directional flow. It is particularly suitable for oxidation ditches, aeration tanks and circulation processes requiring continuous water movement with low energy consumption.
Key Features
-
Optimized hydraulic design: High-efficiency propeller geometry produces strong circulation and uniform mixing.
-
Anti-clogging performance: Backward-swept blades provide a self-cleaning effect and reduce fiber entanglement.
-
Reliable underwater operation: IP68 motor protection, Class F insulation and continuous-duty operation.
-
Long service life: High-quality bearings and double mechanical seals improve operational reliability.
-
Flexible configurations: Cast-iron, stainless-steel and polyurethane propeller options are available.
-
Convenient maintenance: Guide-rail and lifting systems allow the equipment to be raised without personnel entering the tank.
