**Product Specifications**
**Product Overview** The QW (WQ), YW, LW, and GW non-clogging sewage pumps are advanced submersible pumps developed by integrating cutting-edge foreign technology with domestic design features. These pumps are energy-efficient, anti-winding, non-clogging, and equipped with automatic installation and control systems. They are ideal for transporting wastewater containing solid particles and long fibers. Featuring a special impeller design and an improved mechanical seal system, these pumps offer enhanced efficiency in handling solids and fibrous materials. Compared to traditional impellers, the spiral-flow or double-leaf type impellers significantly improve the pump’s capacity and performance, ensuring smooth operation without vibration. **Key Features** 1. Unique spiral or large passage impeller design allows passage of solid particles up to half the pump inlet diameter. 2. Equipped with a sub-impeller (mounted on the same axis as the motor) to ensure stable operation and complete discharge of wastewater. 3. Dynamically balanced rotor and properly arranged bearings reduce radial and axial loads, improving stability and reducing noise. 4. Supports both mobile and fixed installation based on customer requirements. 5. Uses advanced mechanical seals that extend service life to over 8,000 hours. 6. Offers common-type or fully protected models upon request (specify "fully-insured" at order time). 7. Optional liquid level control cabinet enables automatic pump control based on water level. **Working Conditions** - Flow range: 2–800 m³/h - Medium temperature: -15°C to +60°C - Head range: 3–50 m - Medium density: 1.3 × 10³ kg/m³ - Rated speed: 980–2900 r/min - pH range: 5–9 - System pressure: ≤ 0.9 MPa **Accessories Available** Pump, packing, flexible joint, soft pipe, and automatic control devices can be provided as optional accessories. **Structure Drawing**
