1Automatic mixing sewage pump applicable scope:
The automatic mixing sewage pump is suitable for the discharge of severely polluted wastewater in factories and commercial areas, sewage discharge stations in main residential areas, water distribution systems in urban sewage treatment plants, drainage stations in civil air defense systems, water supply equipment in water plants, sewage discharge in hospitals and hotels, municipal engineering construction sites, mining supporting machines, rural biogas digesters, farmland irrigation and other industries. The automatic mixing sewage pump can also be used for clean water and weakly corrosive media.
2、 Automatic mixing and drainage pump usage conditions:
1. The automatic mixing sewage pump series products are suitable for rated voltage of 380V and power frequency of 50Hz
2. The medium temperature does not exceed 40 degrees Celsius, the medium density is ≤ 1150kg/m3, and the pH value is between 5-9;
3. Altitude not exceeding 1000 meters;
4. The annual viscosity of the conveying medium shall not exceed 1000CP;
5. The automatic mixing sewage pump must be completely submerged in water during operation, but the diving depth must not exceed 10m;
6. The material of the automatic mixing sewage pump is mainly cast iron and cannot be used in highly corrosive or highly corrosive media;
Attention: Before selecting or installing the pump, it is necessary to ensure that the actual usage conditions of the pump comply with the above terms to ensure the correct use of the product!

3、 Features of automatic mixing sewage pump:
1. The automatic mixing sewage pump adopts a double blade impeller structure, greatly improving the ability of pollutants to pass through
2. The mechanical seal adopts a new type of friction pair and operates in the oil chamber for a long time;
3. The overall structure is compact, the volume is small, the noise is low, the energy-saving effect is significant, the maintenance is convenient, and it is easy for users to replace;
4. The automatic control cabinet can automatically control the pump's over movement and stop according to the required liquid level changes, without the need for dedicated personnel to supervise, making it extremely convenient to use;
5. Installation methods can be provided according to user needs, which greatly facilitates installation and maintenance. People do not need to enter the sewage pit for this purpose;
6. The automatic mixing sewage pump can be used within the design range while ensuring that the motor will not overload.
