Vertical Pipeline Pump

The LW series vertical pipeline sewage pump is a high-efficiency, energy-saving centrifugal pump specially designed for transporting sewage and wastewater containing solid particles and fibrous materials. Adopting a vertical inline structure, the pump features flanged inlet and outlet that can be directly connected to the pipeline system, eliminating the need for a separate foundation and significantly reducing installation space and construction costs.

Introduce the basic functions of the product




1.High-Efficiency Sewage Transportation 


The core function is to convey various types of sewage and wastewater, stably handling media containing solid particles, long fibers and suspended impurities to meet drainage requirements in different scenarios.


2.Non-Clogging Operation 


Equipped with a large-channel impeller design, it can effectively pass through large-diameter solid particles and fibrous materials, avoiding pump blockage, ensuring continuous and stable operation, and reducing maintenance frequency.


3.Pipeline-Type Convenient Installation 


Adopting a vertical pipeline structure, the flanged inlet and outlet can be directly connected to the pipeline system. It can be vertically installed in the pipeline without a separate foundation, saving installation space and costs.


4.Wide Range of Medium Adaptability 


Suitable for conveying normal-temperature, non-strongly corrosive sewage and wastewater, including domestic sewage, industrial wastewater, rainwater, breeding wastewater and other media.


5.Stable and Reliable Operation 


Matched with a fully enclosed protective motor, it has excellent heat dissipation and waterproof performance, can adapt to harsh working conditions, and realize long-term continuous operation.




Usage Environment




1.Medium Temperature Environment 


Suitable for conveying normal temperature media, with a conventional operating temperature range of 0℃~40℃; customized models with special materials can adapt to high-temperature media (maximum up to 80℃).


2.Medium Property Environment 


Applicable to non-strongly corrosive and non-strongly abrasive sewage and wastewater, including domestic sewage, industrial wastewater, rainwater, breeding wastewater, municipal sewage, etc.; the diameter of solid particles in the medium shall not exceed 1/3 of the pump flow channel diameter, and the fiber length shall not exceed 5 times the pump flow channel diameter.


3.Installation Site Environment 


Can be vertically installed in pipeline systems indoor or outdoor, supporting basements, pump rooms, sewage treatment plants, factory workshops, building floors and other sites; the installation environment should be well-ventilated to avoid the accumulation of a large amount of dust and flammable and explosive gases.


4.Power Supply and Voltage Environment 


Adapt to three-phase AC power supply, with a conventional voltage of 380V/50Hz; can be customized with different voltage specifications such as 220V and 440V according to customer needs, adapting to the power grid standards of different countries and regions. 


5.Altitude and Climate Environment 


Suitable for areas with an altitude not exceeding 1000 meters; the relative humidity of the working environment is not more than 95% (at 25℃), and it can adapt to conventional climate conditions such as temperate and subtropical zones.




Product Advantages




1.Non-Clogging Design for More Stable Operation 


Large-channel impeller and optimized flow channel structure can easily pass through large solid particles and long fiber impurities, completely solving the common blockage problem of sewage pumps, ensuring continuous trouble-free operation, and greatly reducing maintenance frequency.


2.Pipeline-Type Installation for More Convenient Construction 


Vertical integrated structure with flanged inlet and outlet can be directly connected to the pipeline system. It can be vertically installed in the pipeline without a separate foundation, saving 80% of installation space, shortening 50% of the construction period, and reducing installation and civil engineering costs.


3.High Efficiency & Energy Saving for Lower Operating Costs 


Adopting high-efficiency hydraulic model design and matched with energy-saving motor, the pump operation efficiency is 15%~20% higher than that of traditional sewage pumps. Long-term use can significantly reduce electricity costs; at the same time, the motor has excellent heat dissipation performance, extending the service life of the equipment.


4.Compact Structure for Easier Maintenance 


The whole machine has a simple structure, with the pump and motor connected coaxially without complex transmission parts. Daily maintenance only needs to remove the pump cover to inspect and repair core components such as impeller and mechanical seal, no need for professional personnel, greatly saving maintenance time and costs.


5.Wide Application Range for More Flexible Scenarios


It can adapt to a variety of normal-temperature, non-strongly corrosive sewage media, supporting various installation sites such as indoor and outdoor, high and low floors, basements, etc. It meets the sewage discharge needs of different fields such as municipal administration, industry, construction, breeding, with strong versatility.


6.Reliable Operation for Stronger Adaptability 


Matched with a fully enclosed air-cooled motor, the protection grade can reach IP54/IP55, with good waterproof, dustproof and shockproof performance. It can adapt to harsh working environments such as humidity and dust, and realize long-term continuous and stable operation.
