A1: Our QJB submersible mixers cover a wide power range from 0.37 kW to 22 kW, with models like QJB0.37/6-220/3-980/S for low-power needs and QJB22/12-620/3-480/S for high-power applications. This ensures we have a suitable mixer for various tank sizes and mixing intensities.

A2: We offer impellers made from stainless steel or carbon steel, available in both precision-cast and stamped/welded versions. The blades feature a swept-back, optimized design for high efficiency and self-cleaning, suitable for harsh wastewater environments.

A3: Our standard submersible mixers are designed for a maximum diving depth of up to 20 meters. For specific deep-water applications, special designs can be discussed to ensure reliable performance under higher pressures.

A4: The motor features F-class insulation, IP68 protection for complete submersion, and is designed for 24-hour continuous operation. It includes dual mechanical seals for reliability, imported lubricated bearings with a 100,000-hour design life, and protection sensors against leaks and overheating.

A5: For optimal plug-flow mixing effect, the flow velocity should be maintained between 0.15 m/s and 0.3 m/s. Velocities below 0.15 m/s may be ineffective, while those above 0.3 m/s can be inefficient. Our selection service helps determine the right model for your tank.
