WQ Series Submersible Sewage Pump

The WQ Series Submersible Sewage Pump is a high-performance product developed by our company through the assimilation of advanced German pump manufacturing technology. This series features elevated technological specifications, significant energy-saving capabilities, comprehensive system compatibility, and extensive application versatility. Recognized as a key imported product for digestion and localization by the former State Machinery Commission, it has successfully obtained export quality certification and CE marking compliance. Since its market launch, this pump has received widespread acclaim from industrial users, achieving substantial international sales and serving as a domestic substitute for imported equipment in numerous national key construction projects. In 1995, it was designated as a "Torch Program" development project by the State Science and Technology Commission, and in 1997, it was included in the Ministry of Construction's recommended product list and promoted by the State Science and Technology Commission.

1、The WQ Series Submersible Sewage Pump incorporates a large-channel anti-clogging hydraulic component design, enabling efficient passage of solid particles up to 125mm in diameter.

2、Equipped with a water-jacketed circulation cooling system for the motor, ensuring reliable operation under waterless (dry) conditions.

3、Motor designed for minimum 15 starts per hour operation.

4、Motor insulation class rated at F or above.

5、Integrated anti-condensation device automatically performs motor dehumidification, maintaining insulation resistance above 300MΩ even in high-temperature environments to guarantee reliable motor operation.

6、Utilizes an automatic coupling system enabling simplified installation without pump house construction, significantly reducing engineering costs and lowering operational expenses.

7、Comprehensive automatic protection system featuring multifunctional operational display for centralized control and effective protection of all operating conditions.

8、Widely applied in municipal engineering, industrial facilities, commercial establishments, medical institutions, hotels, residential complexes for wastewater, sewage, rainwater discharge containing solid particles and long fibers, as well as water supply and agricultural irrigation systems.

• Discharge of heavily polluted industrial wastewater
• Residential sewage treatment
• Hospital and hotel wastewater management
• Exploration and mining operations auxiliary systems
• Water supply and drainage for water treatment plants
• Municipal sewage treatment plant systems
• Civil defense system drainage
• Urban infrastructure and construction sites

Rural biogas systems and agricultural irrigation

pH range: 5-9; water temperature ≤40℃ (special media including high-temperature, mildly corrosive liquids, and seawater are available through customized configurations).

Fixed Wet Installation: Utilizes the Lanshen Dual-rail Auto-coupling Device, allowing the pump to automatically slide along dual rails to the designated installation position on the base, ensuring secure sealing connection at the discharge port.

Fixed Dry Installation: Mounts the pump base onto a support bracket, suitable for dedicated collection wells and water tank pumping stations. This configuration optimizes space utilization and reduces installation costs, making it an ideal retrofit solution for existing long-shaft pump stations.
