QW large-diameter cast iron submersible sewage pump

1、 Product Overview:
QW unobstructed submersible sewage pumpyesDongquan Pump IndustryA new product developed by integrating the characteristics of domestic water pumps and adopting advanced technology. Due to its excellent energy-saving effect and high quality, as well as the advantages of no blockage, anti winding, reliable performance, automatic control and installation, it has been highly praised by customers. The product has mature performance and all testing indicators meet relevant standards, especially the impeller has passed the dynamic and static balance test. The results show that the pump has no vibration during operation, and the product has achieved excellent results in discharging long fiber garbage and solid particles. The WQ submersible sewage pump adopts a new type of mechanical seal, and its impeller adopts a single (double) channel form. The impeller structure of * is similar to a bent pipe with the same cross-sectional size, which has stronger flow capacity compared to traditional impellers and can smoothly transport long fibers and solid materials. The impeller is equipped with a suitable volute chamber, which further improves its operational efficiency.
2、 Scope of application:
QW unobstructed submersible sewage pumpSuitable for conveying granular sewage and waste from chemical, petroleum, pharmaceutical, mining, papermaking, power plants, urban sewage treatment, municipal engineering, public facility sewage discharge, irrigation of rural biogas digesters and farmland, and water supply equipment for water plants.

4、 Product features:
1QW unobstructed submersible sewage pumpAdopting a large flow channel anti clogging hydraulic component design, it greatly improves the ability of pollutants to pass through, and can effectively pass through 5 times the fiber material of the pump diameter and solid particles with a diameter of about 50% of the pump diameter.
2. Reasonable design, high efficiency, and energy saving.
3. Adopting a dual channel series mechanical seal, the material is hard and corrosion-resistant tungsten carbide, which is durable and wear-resistant, and can ensure the safe and continuous operation of the pump for more than 8000 hours.
4QW large-diameter cast iron submersible sewage pumpCompact structure, small volume, easy to move, simple installation, no need to build a pump room, reducing project costs.
5. There is an oil-water probe installed in the oil chamber to protect the pump.
6. It can be equipped with a fully automatic safety protection control cabinet to monitor the leakage, electric leakage, overload, and overheating of the pump, ensuring reliable and safe operation of the pump.
7. The float switch can automatically control the stop and start of the pump according to the required water level changes, without the need for a dedicated person to supervise.
8. The motor of the unobstructed submersible sewage pump can adopt a water jacket external circulation cooling system to ensure safe operation of the electric pump in a dry state without water.
9QW large-diameter cast iron submersible sewage pumpThe double rail automatic coupling installation system brings convenience to the installation and maintenance of pumps, and people do not need to enter the sewage pit for this.
10. There are two installation methods: fixed automatic coupling installation and mobile free installation, which can meet different usage scenarios.
