Product details
1、 Overview of WQ High Temperature Resistant Stainless Steel Submersible Sewage Pump:
Using a three-phase power supply, the overall stainless steel structure is rust free and corrosion-resistant. According to the different manufacturing materials, it is divided into stainless steel sewage pumps made of 304 material and stainless steel sewage pumps made of 316L material. Whirlpool and double blade impellers have strong sewage discharge capacity and can pass through larger particle diameter pollutants and debris. Suitable for the transportation and discharge of wastewater. Users can choose electric pumps made of different materials according to their needs: electric pumps made of 304 material, with a range of use (pH 4-10). Suitable for general acid and alkali media, electric pumps made of 316L material, with a range of use (pH 0~12). Suitable for industries such as seawater and chemical industry.
2、 Characteristics of WQ High Temperature Resistant Stainless Steel Submersible Sewage Pump
1. Adopting a unique single blade or double blade wheel structure greatly improves the ability of dirt to pass through
2. The overall structure is compact, with small volume, low noise, significant energy-saving effect, easy maintenance, no need to build a pump room, and can work underwater, greatly reducing project costs.
3. A fully automatic control cabinet can be equipped according to user needs to automatically protect the pump from water leakage, rain leakage, overload, and overheating, improving product safety and reliability.
4. The float switch can automatically control the start and stop of the pump according to the required liquid level changes, without the need for special supervision, making it extremely convenient to use.
There are two different installation methods, fixed automatic coupling installation system and mobile free installation system.
3、 WQ high-temperature resistant stainless steel submersible sewage pump usage conditions:
1. The temperature of the medium should not exceed 90 ℃, and the density should be 1.0-1.3kg/m3304. It is suitable for use within the pH range of 4-10. If it exceeds this range, it is recommended to use 316. If the pH of the sewage is not known, the volume concentration or mass concentration of the acid or alkali should be provided to facilitate the calculation of the actual pH. Alternatively, follow the previous use of similar water pumps to determine which material to choose.
In general, pumps must be used within the range of head to ensure that the motor is not overloaded. If it is necessary to use within the full head range, it should be specified separately when ordering.
During operation, the motor current shall not exceed the rated current of the motor.
4. When in use, more than half of the motor of the water pump must be immersed in water.
4、 The main uses of WQ high-temperature resistant stainless steel submersible sewage pump are:
1. Municipal engineering and construction sites.
2. Urban sewage treatment and discharge system.
3. Wastewater discharge from enterprises and units.
4. Sewage discharge in residential areas.
5. Subway, basement, civil air defense engineering.
6. Wastewater discharge from hospitals, hotels, and high-rise buildings.
7. Waterworks, water conservancy projects, etc.
8. Hot water is pumped from power plants and steel mills.
