Product details

Model Meaning
YW无堵塞排污液下泵型号意义

Product Introduction
The YW unobstructed sewage submersible pump is developed through absorption and conversion, and 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.

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, small in size, low in noise, 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;

Product Usage
YW unobstructed sewage submersible 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 waterworks, sewage discharge in hospitals and hotels, municipal engineering construction sites, mining supporting machinery, rural biogas digesters, farmland irrigation and other industries. It can also be used for conveying granular sewage and pollutants, as well as for clean water and weakly corrosive media.

working conditions
A、 The operating environment temperature of the pump is ≤ 40 ℃, and the humidity is ≤ 95%; Altitude ≤ 1000 meters.
B、 The medium temperature shall not exceed 60 ℃, and the medium density shall be 1-1.3kg/dm3.
C、 The range of use for cast iron material is from pH 5 to 9.
D、 Stainless steel material can be used with general corrosive media.
E、 The altitude of the usage environment should not exceed 1000 meters. If it exceeds the above conditions, it should be mentioned when placing an order to provide you with more reliable products.
Note: If the user has special requirements for temperature, medium, etc., please specify the detailed information of the conveying medium when ordering, so that our unit can provide more reliable products.
