Product details

LW/WL type unobstructed vertical sewage pump


1、 Product Overview:
The LW/WL type unobstructed vertical 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 winding, unobstructed, automatic installation, and automatic control. It has a unique effect in the discharge of solid particles and long fiber waste.
This series of 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 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、 Product features:
1. By adopting a unique single or double blade impeller structure, the ability of pollutants to pass through is greatly improved, which can effectively pass through 5 times the fiber material of the pump diameter 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, the volume is small, the noise is low, the energy-saving effect is significant, the maintenance is convenient, and there is no need to build a pump room. It can work underwater, greatly reducing the project cost.

3、 Product Usage:
LW/WL type unobstructed vertical sewage pump is suitable for conveying granular sewage and pollutants in industries such as chemical, petroleum, pharmaceutical, mining, paper industry, cement plant, steel plant, power plant, coal processing industry, as well as urban sewage treatment plant drainage system, municipal engineering, construction sites, etc. It is also used for pumping clean water and corrosive media.
