QW/WQ Type Submersible Sewage Pump

The WQ/QW type submersible sewage pump is a single-stage single-suction centrifugal sewage pump where the motor and the pump are integrated coaxially and can work completely submerged in the medium. The core design concept is "efficiency without blockage", specifically designed for the transportation of sewage, wastewater and slurry containing solid particles, long fibers, sand and other impurities. This series of pumps are developed based on introducing advanced foreign technologies and combined with domestic actual working conditions. They have the advantages of a wide efficiency range, strong throughput capacity, long service life, convenient installation and complete control functions.

1.Years of production experience | Focus on quality - national standard motors | High cost-effectiveness | Easy installation | Long lifespan | Cast iron, 304, 316L stainless steel materials

2.The company has a high-level pump performance testing center in China. All of its products are designed using advanced design methods such as CAD software and CFD computational fluid dynamics software. The products undergo more than ten processes including precision casting, hot forging, welding, heat treatment, fine processing, and assembly.

3.Multiple sealing and all-round protection: A double-channel series mechanical seal is adopted. The sealing surfaces are made of hard and corrosion-resistant tungsten carbide or silicon carbide materials and operate within an oil chamber. It can operate safely for over 8,000 hours continuously. Heat-sensitive elements are pre-installed inside the motor, and a high-precision water leakage detector is set in the oil chamber to monitor the status in real time. It can be equipped with a fully automatic safety protection control cabinet, which provides absolute protection against water leakage, electric leakage, overload and overheating of the pump.

Municipal environmental protection and sewage treatment: Drainage systems of urban sewage treatment plants, municipal engineering and water discharge from construction sites.
Industrial discharges: Severe polluted wastewater discharges from industries such as factories, mines, thermal power plants, petroleum, chemical, pharmaceutical, papermaking, metallurgy, etc.
Public service facilities: Sewage discharge stations in hospitals, hotels, high-rise buildings, residential areas, as well as subway, basements, and civil defense systems.
Agricultural water conservancy and rural construction: Rural biogas digesters, farmland irrigation, sewage discharge from livestock farms, and river sediment suction.
Water supply facilities: Water supply devices in water treatment plants.
Emergency rescue: Applicable for frequently mobile or temporarily urgent situations, such as flood control and drainage.
