* Different lengthes of guide bar can be made to order.




  • Compact structure, small volume, light weight, easy maintenance and installation, long service life.


  • Optimal impeller for high efficiency, and sweep back type blade to prevent clogging, also can be self-cleaning.


  • When use together with aerating system, it can reduce power consumption, increase oxygen content, and prevent sedimentation.


  • F class insulation for motor wiring, IP 68 class protection level, maintenance-free type bearing, be with oil leakage detection and overheat protection, which can assure stable operation for the motor.


  • The mixer will be equipped with two way mechanical seal.


  • The mixer can be used either with flow guide sleeve or not. The faring can enhance the efficiency and control the flow spraying.




Compared with the conventional long axle stirrer, model QJB submersible stirrer features the advantage able to produce different flow directions, and with the the different positions, it can get multiple flowing modes of different effects so as to create a better flowing mode in the pool to remove the dead corner of stirring.
