Product Overview of JYWQ and JPWQ Automatic Mixing Sewage Pumps

The JYWQ and JPWQ series of automatic‑agitation submersible sewage pumps are a new generation of environmentally friendly products developed using advanced hydraulic models, built upon the integration of cutting‑edge foreign technologies. They offer unique capabilities in handling solid particles and long‑fiber waste, as well as in minimizing sedimentation within sewage pits. These pumps boast advanced, mature hydraulic performance, with key performance parameters that meet or surpass the state‑of‑the‑art levels of comparable foreign products.

The JYWQ and JPWQ automatic‑agitation sewage pumps are based on the WQ submersible sewage pump, incorporating an automatic stirring device that rotates with the motor shaft to generate powerful agitation. This forces sediment in the wastewater tank into suspension, which is then drawn into the pump and discharged, thereby enhancing the pump’s resistance to clogging and its capacity for efficient waste removal. The system simultaneously accomplishes drainage, sludge removal, and sediment clearance, reducing operating costs while delivering clear environmental benefits and demonstrating significant technological advancement and practical utility.

JYWQ and JPWQ automatic mixing sewage pumps feature a large‑diameter, anti‑clogging hydraulic design; an oil‑chamber sealing monitoring system; a fully automatic safety‑protection control cabinet that continuously monitors pump operation; and a dual‑rail automatic coupling installation system, ensuring convenient installation and maintenance. The built‑in automatic mixing mechanism thoroughly agitates the wastewater, enabling more complete drainage.

Application Scope of JYWQ and JPWQ Automatic Mixing Sewage Pumps

The JYWQ‑type automatic agitating submersible sewage pump is suitable for conveying sewage and sludge containing solid particles in industries such as chemical processing, petroleum, pharmaceuticals, mining, papermaking, power plants, as well as in urban wastewater treatment, municipal engineering, and public‑facility drainage applications.

Product Features of the JYWQ and JPWQ Automatic Mixing Sewage Pumps

1. Utilizing the pump’s own discharge pressure, it stirs and homogenizes the settled sludge in the sewage tank, thereby effectively achieving the complete removal of sediment from the tank.

2. The hydraulic components feature a large‑diameter flow path designed to resist clogging, significantly enhancing the pump’s ability to handle debris. They can effectively pass fibrous materials up to five times the pump’s nominal diameter and solid particles with diameters of approximately 50% of the pump’s nominal diameter.

3. The design is well-optimized, the accompanying motor is appropriately matched, resulting in high efficiency and significant energy savings.

4. The mechanical seal employs a double‑stage tandem configuration, with a hard, corrosion‑resistant tungsten carbide material that ensures durability and wear resistance, enabling the pump to operate safely and continuously for over 8,000 hours.

5. The pump features a compact design, small footprint, and easy portability; it is simple to install and requires no dedicated pump house—simply submerge it in water to operate, thereby reducing construction costs.

6. The oil chamber is equipped with an oil‑water probe to provide absolute protection for the pump. Wenzhou

7. It can be equipped with a fully automatic safety protection control cabinet that provides comprehensive protection against pump leakage, electrical leakage, overload, and overheating, thereby enhancing the product’s safety and reliability.

8. The float switch can automatically start and stop the pump according to the desired water level, eliminating the need for dedicated supervision.

9. The motor may be equipped with a water-jacketed external circulation cooling system, ensuring safe operation of the electric pump in dry‑run conditions.

10. The dual-rail automatic coupling installation system greatly simplifies pump installation and maintenance, eliminating the need for personnel to enter the sewage pit.

11. Installation options include fixed automatic coupling installation and mobile free‑standing installation, catering to various application scenarios.
