Product Description
Model Code Explanation
Product Introduction
The YW Non-Clogging Submersible Sewage Pump is developed through absorption and transformation, and all performance indicators meet national standards for similar products. Featuring a unique single (or double) channel impeller, this pump has strong sewage discharge capacity and can effectively pass fibrous materials up to five times the diameter of the pump inlet and solid particles with a diameter up to 50% of the pump inlet size. The dynamic seal utilizes two special material hard alloy mechanical seals, made of cast iron and stainless steel.
Product Features
- Uses a dual-blade impeller structure to significantly improve the ability to pass waste.
- The mechanical seal uses a new type of friction pair, continuously operating in the oil chamber.
- Compact overall structure, small size, low noise, easy maintenance, and convenient for users to replace parts.
- The automatic control cabinet can adjust the pump operation and stop according to the required liquid flow, without the need for dedicated supervision, making it extremely convenient to use.
- The pump can be equipped with various installation methods according to user requirements, greatly facilitating installation and maintenance, eliminating the need to enter the sewage pit.
- The pump ensures that the motor will not overload within the designed range of use.
- If paired with an outdoor motor, the pump can be installed outdoors without the need for a pump house, saving on construction costs.
Applications
The YW Non-Clogging Submersible Sewage Pump is suitable for applications such as the discharge of heavily polluted wastewater in factories and commercial environments, wastewater stations in residential areas, water distribution systems in urban sewage treatment plants, drainage stations in civil defense systems, water supply equipment in water plants, wastewater discharge from hospitals and hotels, municipal construction sites, mining equipment, rural biogas pits, agricultural irrigation, and more. It is designed to handle wastewater with particles, sludge, and can also be used for clean water and slightly corrosive media.
Working Conditions
- The pump environment temperature should be ≤ 40°C, humidity ≤ 95%, and altitude ≤ 1000 meters.
- The medium temperature should not exceed 60°C, with a density range of 1 to 1.3 kg/dm³.
- For cast iron models, the pH range of the medium is 5 to 9.
- For stainless steel models, the pump can be used with general corrosive media.
- If the usage environment exceeds 1000 meters in altitude, please specify when placing the order so we can provide a more reliable product for your specific needs.
Note: If there are special requirements for temperature, medium, etc., please specify the details of the conveying medium when placing the order so that we can provide a more reliable product.

FAQs for Overseas Buyers
1. What liquids can the YW submerged sewage pump handle?
It handles sewage, sludge, slurry, wastewater, fluids with fibers, and solid-liquid mixtures.
2. Does the pump support fully automatic control?
Yes, it can use an automatic control cabinet to start and stop based on water level.
3. What is the maximum allowable liquid temperature?
The medium temperature should not exceed 40°C, as stated on page 3 of the PDF.
4. How deep can the pump be submerged?
The installation depth generally ranges from 0.5 to 7 meters.
5. Can the pump run dry?
No. Running dry may damage the mechanical seals and cause motor overload.
6. What is the typical pH range of applicable liquids?
The pH range is 5–9, suitable for most industrial and municipal wastewater.
7. Is OEM customization available?
Yes, including materials, power configurations, installation plates, and flange sizes.
