WQ Series Sewage Submersible Pump

**Product Specifications of WQ Series Submersible Sewage Pump** --- **Introduction to the WQ Series Submersible Sewage Pump** The WQ series submersible sewage pump is a highly efficient and reliable solution designed for a wide range of applications. It is widely used in municipal projects, industrial buildings, hotels, hospitals, civil defense systems, and mining operations. This pump is ideal for handling wastewater, rainwater, and domestic water that contains solid particles and long fibers. One of the key advantages of the CNBM WQ series is its ability to operate efficiently without clogging or blockages. It features an auto-coupling system, high reliability, and automatic control functions, making it a preferred choice in demanding environments. --- **Technical Performance of the WQ Series Sewage Pump** - **Discharge Diameter:** 50–600 mm - **Flow Rate:** 10–8000 m³/h - **Head Range:** 5–60 meters - **Power Output:** 1.5–315 kW - **Solid Passing Diameter:** 20–145 mm These pumps are built to handle heavy-duty tasks and maintain consistent performance even under challenging conditions. --- **Operating Conditions for the WQ Series Sewage Pump** - **Rated Voltage:** 380V / 460V, 50Hz / 60Hz, 3-phase AC - **Medium Temperature:** Below 40°C - **pH Range:** 4–10 - **Solid Content:** Less than 2% by volume - **Medium Density:** Less than 1200 kg/m³ These specifications ensure the pump operates safely and effectively in various industrial and municipal settings. --- **Structural Features of the WQ Series Sewage Pump** The WQ series is equipped with advanced safety and protection mechanisms to ensure long-term, trouble-free operation. Key features include: 1. **Cable Sealing System:** Prevents cable leakage and ensures electrical safety. 2. **Thermal Protector:** Protects the motor from overheating and extends its lifespan. 3. **External Cooling System:** For motors above 18.5 kW, this design ensures safe operation even at low water levels. 4. **Floating Switch:** Installed at the bottom of the motor chamber to protect the mechanical seal. 5. **Oil-Water Probe:** Located at the top of the oil chamber between the pump and motor to detect leaks and trigger protective measures. 6. **High-Quality Mechanical Seal:** Made from tungsten carbide, silicon carbide, and hard metal alloys to prevent water ingress and ensure reliable operation. 7. **Auxiliary Impeller:** Balances pressure on the mechanical seal and prevents water from entering the oil chamber. 8. **Unique Impeller Design:** Wide passage allows large solids and long fibers to pass freely, reducing clogging and improving efficiency. 9. **Replaceable Wear Ring:** Ensures optimal performance by maintaining the correct clearance between the impeller and casing. --- **Impeller Design and Functionality** The impeller is specifically designed to allow waste materials such as paper, soft goods, and garbage bags to pass through without clogging. The flow channels are widened to accommodate larger solids, and the design is optimized to reduce vibration during operation. Whether it's a small or large pump, the impeller ensures smooth and efficient movement of the medium, enhancing overall performance and longevity. --- **Product Images of WQ Series Sewage Submersible Pump**
