The LW type non clogging submersible sewage pump is a new generation of pump products developed based on the introduction of advanced foreign technology and the characteristics of domestic water pump usage. It has significant energy-saving effects, anti entanglement, non clogging, automatic installation, and automatic control. It has a unique effect in the discharge of solid particles and long fiber waste. This series of sewage pumps adopts a unique impeller structure and a new type of mechanical seal, which can effectively transport solids and long fibers. Compared with traditional impellers, the impeller of this sewage pump adopts a single channel or double channel form, which is similar to a curved pipe with the same cross-sectional size and has very good flow characteristics. Coupled with a reasonable volute chamber, the pump has high efficiency and the impeller has undergone dynamic and static balance tests, making the pump operate without vibration.

2、 Characteristics of LW type vertical unobstructed sewage pump:
1. Adopting a unique single or double blade impeller structure greatly improves the ability of pollutants to pass through, effectively passing through 5 times the diameter of the sewage pump and solid particles with a diameter of about 50% of the pump diameter.
2. The mechanical seal adopts a new type of hard and corrosion-resistant titanium tungsten material, which can ensure the safe and continuous operation of the pump for more than 8000 hours.  
3. The overall structure is compact, small in size, low in noise, and has significant energy-saving effects. It is easy to maintain and does not require the construction of a pump room. It can work underwater, greatly reducing project costs.  

3、 The main purpose of the sewage pump is:
Suitable for conveying granular wastewater and waste in industries such as chemical, petroleum, pharmaceutical, mining, papermaking, cement plants, steel mills, power plants, coal processing, as well as urban sewage treatment plant drainage systems, municipal engineering, construction sites, etc. It is also used for pumping clean water and corrosive media.
