WQ Type Stainless Steel Sewage Pump

The WQ type stainless steel sewage pump is a submersible non-blocking sewage discharge equipment made of all stainless steel. It is specially designed for transporting sewage containing solid particles, fibers and corrosive media.
This pump adopts an integrated structure where the pump and the motor are coaxial. It works entirely submerged in the liquid and does not require the construction of a pump room. The installation and maintenance are very convenient.

High-efficiency prevention: With the unique single-flow or double-flow impeller design, the flow channels are wide and resemble bends, which can effectively pass through fibers with a diameter 5 times that of the pump's diameter and solid particles with a diameter approximately 50% of the pump's diameter. It is anti-tangling and free of blockages. .
Corrosion-resistant and durable: The pump body is made of 304 or 316L stainless steel, which is resistant to acid and alkali corrosion (with a pH value ranging from 4 to 10 or wider), and is suitable for corrosive environments such as those in the chemical industry and seawater. .
Sealing is reliable: The mechanical seal adopts a double-channel series design. The material is hard and corrosion-resistant tungsten carbide or titanium tungsten, which enables the pump to operate safely and continuously for more than 8,000 hours. .
Intelligent protection: The sealed oil chamber is equipped with a high-precision water leakage detection sensor. The stator winding is pre-installed with thermal sensitive elements. A fully automatic control cabinet can be configured to achieve automatic monitoring and protection against water leakage, electrical leakage, overload and overheating.

The WQ type sewage pump is a type of centrifugal submersible sewage pump. . The impeller, which is coaxial with the motor drive, rotates at high speed. This causes the liquid to be thrown from the center to the edge of the impeller under the centrifugal force, and then flows through the volute channel for collection and pressure increase before being discharged. . The "no blockage" feature is fundamentally based on the unique wide-flow channel impeller structure, which enables large particles and long fibers to pass through smoothly. The dual-end mechanical seal and oil chamber isolation design ensures the dryness and safety of the motor cavity.

Municipal and Public Facilities: Urban sewage treatment plant drainage system, subway, basement, civil defense engineering drainage station, municipal engineering and construction site slurry discharge.
Industrial Wastewater Treatment: Severe polluted wastewater discharge from industries such as chemical, petroleum, pharmaceutical, mining, papermaking, cement, steelmaking, power plants, coal processing, etc.
Commercial and Civil: Sewage drainage stations for hospitals, hotels, high-rise buildings, residential communities; water supply devices for waterworks.
Agriculture and Livestock: Rural biogas digesters, farmland irrigation, livestock wastewater discharge and fish pond aeration for pond cleaning and oxygenation.
