The QJB submersible mixer should be able to operate continuously under the following conditions:
1. The maximum medium temperature shall not exceed 40 ℃;
2. The pH value of the medium is between 5 and 9;
3. Liquid density not exceeding 1150kg/m3;
4. Long term diving operation, with a diving depth generally not exceeding 20m.

Selection precautions
To ensure optimal results, please provide the following information:
1. Application purpose
2. Pool type
3. Pool size
4. The characteristics of the medium include viscosity, density, solid content, etc.
5. The required matching power for the mixer is determined by the volume, density, viscosity, and mixing depth of the mixed liquid. Depending on the specific situation, one or more mixers should be used.
6. The mixer must work completely submerged in water and cannot operate in flammable or explosive environments or environments with highly corrosive liquids.
7. For selection issues, please contact the supplier.
