Product Description
Model Code Explanation

Product Description
The YW Series Submerged Non-Clog Sewage Pump is developed through advanced absorption and transformation technology, with all performance indicators reaching the national standards of similar products.
With a unique single (or double) channel impeller, the pump has strong sewage-handling capability and can effectively pass fibers up to 5 times the pump inlet diameter and solid particles up to 50% of the pump inlet diameter.
The dynamic seal adopts two sets of hard-alloy mechanical sealing units made from special materials. The pump is available in cast iron and stainless steel.
Product Features
1. Dual-vane impeller structure greatly improves the solids-passing capacity.
2. Mechanical seal adopts a new wear-resistant pair and operates for long periods inside an oil chamber.
3. Compact structure, small size, low noise, easy to maintain, and convenient part replacement.
4. Automatic control panel allows automatic start and stop according to liquid level changes—no need for manual supervision.
5. Various installation methods can be configured according to user needs, allowing installation and maintenance without entering the sewage pit.
6. Operates safely within the designed performance range to ensure the motor is not overloaded.
7. When equipped with an outdoor-type motor, no pump house is required—can be installed outdoors directly, reducing installation cost.
Product Applications
The YW Series Submerged Non-Clog Sewage Pump is suitable for the discharge of heavily polluted industrial and commercial wastewater, residential sewage pumping stations, municipal sewage treatment plant discharge systems, civil defense drainage stations, water supply equipment for waterworks, hospital and hotel sewage discharge, municipal construction sites, mining auxiliary equipment, rural biogas digester systems, farmland irrigation, and similar applications.
It is capable of transporting sewage containing solids, sludge, wastewater, as well as clean water and weakly corrosive media.
Operating Conditions
A. Ambient temperature ≤ 40°C; humidity ≤ 95%; installation altitude ≤ 1000 m.
B. Medium temperature ≤ 60°C; medium density 1–1.3 kg/dm³.
C. Applicable pH range for cast iron pumps: 5–9.
D. Stainless steel pumps can handle general corrosive media.
E. Installation altitude should not exceed 1000 m; if exceeding this value, please specify when ordering to ensure a reliable configuration.
Note: If the user has special requirements regarding temperature, medium type, or other conditions, please specify detailed medium information when ordering so we can provide a more reliable product.
