Submersible Mixers Description
QJB type Submersible Mixer, a key equipment used in the water treatment technology, can meet the technological requirement for homogeneity and fluidity of solid-liquid two-phase flow and solid-liquid-gas three phase flow in biochemical course of the water treatment process. It is composed of the submersible motor, impeller, and installation system etc.. The submersible mixer is in direct connection structure. Comparing with the traditional high-power electric motor that retards speed by a speed reducer, it is highlighted by compact structure, low energy consumption, facile maintenance. The impeller shaped by finishing casting or punching, which has high precision, forceful thrust as well as simple, nice-looking and streamlined profiling. The series of products are applicable to the places that requires for solid- liquid agitating or mixing.
Submersible mixers are suitable for promoting and stirring sewage containing suspended solids, thin mud, industrial process liquids, etc. in the process of sewage treatment plants, creating water flow, strengthening mixing function, and preventing sludge sedimentation. It is an important process in municipal and industrial sewage treatment processes. equipment.

Submersible Mixers Application
For industrial wastewater treatment and tap water/sewage treatment
For environmental conservation in ponds and rivers
For artificial water flow in amusement facilities
For mixing, stirring, dissolving, density equalization and aeration
Energy-saving Submersible Mixers Selection
- The mixer must be submerged in water to work, and it cannot work in flammable and explosive environments or environments with strong corrosive liquids;
- Pool type;
- The characteristics of the medium include viscosity, density, solid content;
- The matching power required by the mixer is determined according to the size of the volume, the density, viscosity and mixing depth of the stirring liquid. One or more mixers should be used according to the specific situation.
