Submersible mixer

Purpose

The submersible mixers in our company include mixing agitator and low-speed flow propeller, mainly used for: The purposes of mixing, agitating and making ring flows in the process of municipal and industrial sewage treatment: activated sludge tank, bioreactor tank, mixing tank,sludge silos, equalizing reservoir, sewage tank and etc. ;

The maintenance equipment for the landscape water environment, improving the quality of the water body; Creating water flow, effectively preventing the sedimentation of the suspended substances.

Features

● The two rows of independent mechanical sealing ensure the long-term and reliable operation of the submersible motor.

● The international well-known high-quality bearings have longer service life, which are maintenance free.

● The unique sealing design for the cables removes the hidden danger of water leakage for the cables.

● The shaft of the motor employs the stainless steel, and the rotors are inspected with the use of dynamic balancing,

● leading to smooth rotation.

● The in-built leakage sensor and the device for the overtemperature protection for the windings of the stator( No leakage sensor for PJ 0.37/6 or PJ 0.55/4).

● The mixer agitators have the stainless steel pressing impeller, which are of the sweptback shape through the optimized design, resulted in high efficiency and self-cleaning function.

● The vanes of the low-speed flow propeller are made of enhanced PU, which are sweptback shape, have the self-cleaning function, the smooth and streamlined propeller surface distributes the propelling power equally.

Mixing agitator (With dome)

Mixing agitator

● On the low-speed flow propeller, all the tightening pieces which will contact media employ the stainless-steel material;

● The decelerator employs integrated reducer with high safty coefficient, whose standard configuration is CYCLO, you can also choose helical gear speed reducer.

Low-speed flow propeller

Conditions of usage

● The highest temperature of the media shall not exceed 40℃

● The pH value of the media: 5~9

● The density of the media shall not exceed 1150kg/m3

● The depth of submersion shall not exceed 20m

● The electric power supply: 380V, 50Hz

● The motor: F class insulation and in accordance with IP68, continuous operating in 24hr

● The submersible mixer must operate in the complete submersion into water
