Characteristics of LW vertical sewage pump Working principle of sewage pump

Description :

　　The LW series vertical sewage pump is suitable for the discharge of severely polluted wastewater in industrial and mining enterprises, commercial areas, sewage discharge stations in residential areas, urban sewage treatment plant drainage systems, civil air defense system drainage stations, water supply equipment in water plants, sewage discharge in hospitals and hotels, municipal engineering construction sites, exploration, mining supporting equipment, rural biogas digesters, farmland irrigation and other industries. It can also be used to transport granular sewage and pollutants, as well as clean water and corrosive media. The flow rate range for transporting liquids is 7-3000m3/h, the head range is 7-60m, the matching power range is 0.55-315KW, and the caliber range is from φ 25 to φ 500mm.

　　Usage conditions of LW vertical sewage pump

　　1. The operating environment temperature of the pump is ≤ 40 ℃, and the humidity is ≤ 95%;

　　2. The medium temperature shall not exceed 60 ℃, and the medium density shall be 1-1.3kg/dm3.

　　3. The use range of cast iron material is PH5-9.

　　4. 1Cr18Ni9Ti stainless steel material can be used with general corrosive media.

　　5. The altitude of the usage environment should not exceed 1000 meters.

　　LW vertical sewage pump product features

　　1. By adopting a single blade or double blade impeller structure, the passage capacity of pollutants is greatly improved, which can effectively pass through 5 times the fiber material of the pump diameter;

　　2. The mechanical seal adopts a new type of hard all metal corrosion-resistant tungsten carbide material, which allows it to operate in the oil chamber for a long time and can ensure the safe and continuous operation of the pump for more than 8000 hours;

　　3. The overall structure is compact, the volume is small, the noise is low, and the energy-saving effect is significant. It is easy to maintain and adopts standard Y (Y2) series motors, which are convenient for users to replace;

　　4. The automatic control cabinet can automatically control the start and stop of the pump according to the required liquid level changes, without the need for dedicated personnel to supervise, making it extremely convenient to use;

　　5. Installation and maintenance are extremely convenient, and people do not need to enter the sewage pit for this purpose;

　　6. Can be used within the full head range while ensuring that the motor does not overload;

　　7. If the pump is equipped with an outdoor motor, there is no need to build a pump room, and it can be directly installed outdoors to save costs;

　　8. The pump is a vertical structure.
