Product details
1Large flow pipeline sewage pumpproduct overview
The GW pipeline sewage pump is a new generation of pump products that has been successfully 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, non clogging, automatic installation, and automatic control. It has a unique effect in the discharge of solid particles and long fiber waste. The GW type pipeline type unobstructed sewage pipeline pump adopts a unique impeller structure and a new type of mechanical seal, which can effectively transport solid substances 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.
The LW type non clogging vertical pipeline sewage pump is developed by introducing high-efficiency and energy-saving non clogging sewage pumps from abroad and organizing the technical strength of our unit. All performance standards meet or exceed similar product technologies at home and abroad. Due to the use of a unique single channel impeller, the dynamic seal adopts two sets of special materials for hard alloy mechanical sealing devices, and the motor oil chamber is separated. It has the advantages of non clogging, durability, accurate profile, easy use and maintenance, high efficiency, and significant energy saving. It is a new product of pump upgrading in China and is highly welcomed by users. This pump has multiple models and different structural forms to choose from.

IIILarge flow pipeline sewage pumpProduct Features
Product features of GW pipeline sewage pump:
1. The pump is a vertical single suction single-stage centrifugal sewage pump, with the inlet and outlet centerlines on the same horizontal line and the same inlet and outlet flanges, making installation and disassembly very convenient, occupying a small area, and can be installed at any position in the pipeline like a valve.
2. The pump and motor are directly connected and coaxial, belonging to the electromechanical integration product, with compact structure and stable performance.
3. Adopting a high flow and anti clogging hydraulic component design, it greatly improves the ability of pollutants to pass through, effectively passing through 5 times the fiber material of the pump diameter and solid particles with a saliva diameter of about 50% of the pump diameter.
4. Reasonable design, reasonable matching motor, high efficiency, significant energy-saving effect.
5. The mechanical seal adopts hard and wear-resistant tungsten carbide, which has the characteristics of durability and wear resistance, and can ensure the safe and continuous operation of the pump for more than 8000 hours.
6. Advanced hydraulic performance, high overall efficiency, and low operating noise.
7. By adding protective covers to the fan blades of the motor, the entire machine can be operated outdoors without the need for a machine room, which can save a lot of infrastructure costs.
8. Use within the range of head to ensure that the motor is not overloaded.

LW series upright unobstructed sewage pump product features:
1. Adopting a double blade impeller structure greatly improves 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, and the energy-saving effect is significant. It is easy to maintain and convenient for users to replace;
4. The automatic control cabinet can automatically control the pump's over movement and stop according to the required liquefaction 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. Can be used within the design scope 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 and used outdoors to save costs;

6、 Main purpose
The main purpose of GW pipeline sewage pump is:
The GW type pipeline type unobstructed sewage pump is suitable for the discharge of severely polluted wastewater in factories and 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 machines, 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 weakly corrosive media.
The LW series upright non clogging sewage pump is mainly used for:
The LW vertical pipeline sewage pump has a unique and stable base installation design, which saves space and has strong overcurrent capacity. Cost saving, easy to use, and widely applicable. LW pumps are not only 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, but also for transporting sewage and pollutants with particles, as well as for transporting clean water and weakly corrosive media.
