Overview of unobstructed vertical sewage pump and LW pipeline sewage pump:
The LW vertical sewage pump is developed by introducing advanced foreign technology and absorbing and transforming it. All performance indicators meet the national standard for similar products. Due to the use of unique single (double) channel impellers, it has strong drainage capacity and can effectively pass through 5 times the diameter of the pump and solid particles with a diameter of 50% of the pump diameter. The dynamic seal adopts two sets of special hard alloy mechanical seal devices made of cast iron and stainless steel. The LW vertical sewage pump is 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 auxiliary machinery, 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.
Non clogging vertical sewage pump, LW pipeline sewage pump product features:
1. The mechanical seal adopts a new type of friction pair and operates in the oil chamber for a long time;
2. 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
3. Adopting a double blade impeller structure greatly improves the ability of pollutants to pass through
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;

Structural description of LW vertical sewage pump:

The LW vertical sewage pump is a single suction volute pump equipped with non clogging and anti winding single (double) large channel impellers, which have good passing capacity.
The LW vertical sewage pump has two structural forms: one is that the motor is directly coaxial with the pump, and the other is that it is connected by a coupling, and the motor adopts a standard vertical motor. The structural diagram is as follows, and each structural form has two types of base connection forms. One is the inlet horizontal suction, which has a corner function and can be placed at 0 °, 90 °, 180 °, 270 ° according to usage requirements for pipeline connection. The other is the inlet axial suction, which is convenient for vertical installation.
LW vertical sewage pump usage conditions:
1. The LW vertical sewage pump series products are suitable for rated voltage of 380V and power frequency of 50Hz
2. The medium temperature does not exceed 40 degrees Celsius, the medium density is ≤ 1150kg/m3, and the pH value is between 5-9;
3. Altitude not exceeding 1000 meters;
4. The annual viscosity of the conveying medium shall not exceed 1000CP;
5. The main material of the product is cast iron and cannot be used in highly corrosive or corrosive media;
Attention: Before selecting or installing, make sure that the actual usage conditions of the pump comply with the above terms to ensure the correct use of the product!
