Steel Submersible Mixer, QJB2.2/8-320/3-740S, 4KW for stirring sewage water



About QJB mixer

QJB series submersible mixer is suitable for both aeration and anaerobic tanks in the industrial and city’s sewage treatment to provide the power for the cycle of the water in the tank and establish the water flow in the phases of nitration, de-nitrification and phosphor removal.


The submersible mixers are mainly used for mixing, agitating and making ring flows in the process of municipal and industrial sewage treatment and can also be used for equipment maintenance of the landscape water circulation through agitation, they can achieve the function of creating water flow, improving water quality, increasing oxygen content in the water and effectively preventing the sedimentation of the suspended substances.


Working Conditions


The submersible mixer can be continuous operation in the conditions as below:

  • The maximum medium temperature be less than 40℃
  • Medium PH value be in 5~9
  • Medium density be less than 1150kg/m3
  • Continuous operation, the depth be less than 20m

N.W. of mixer without installing system


* Cast iron material, or higher 316 stainless steel can be made to order.





1.compact structure,small volume,light weight, easy operation maintenance,fast installation,long service life etc.


2.the blade has the self-cleaning function, can prevent sundries wind,blocking


3.can combine with aeration system to make energy reduced greatly, greatly increase oxygen volume, effective prevent sediment.


4.motor winding is F grade insulation, protection grade is IP68.


5.all fastener is stainless steel.


Working Principle


The propeller blade of a special structure starts slow moving driven by the under-water motor to produce a powerful water flow flowing in a lower tangential direction to make the liquid’s power increased and produce strong stirring to reduce the precipitation under the water, thus realizing liquid stirring and flowing.
