product overview

The WQ automatic coupling submersible sewage pump is a new generation of pump product developed by our company based on the introduction of advanced foreign technology and the characteristics of domestic water pump usage. It has the features of anti entanglement, no blockage, automatic installation and automatic control, and has unique effects in the discharge of solid particles and long fiber garbage. The hydraulic performance of this series of sewage pumps is advanced and mature. After performance testing, all indicators of the products meet the relevant design requirements.

scope of application

Suitable for transporting granular wastewater from mining, chemical, petroleum, pharmaceutical, papermaking, power plants, urban sewage treatment, municipal engineering, public facility discharge, and other industries.

Product Features

1. The dual rail automatic coupling installation system brings great convenience to the installation and maintenance of pumps, and people do not need to enter the sewage pit for this.
2. There are two installation methods: fixed automatic coupling installation and mobile free installation, which can meet different usage scenarios.
3. Adopting 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.
4. Reasonable design, high efficiency, and significant energy-saving effect.
5. Compact structure, small volume, easy to move, simple installation, no need to build a pump room, reducing project costs.
6. 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.
7. There is an oil-water probe installed in the oil chamber to provide absolute protection for the pump.
8. 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.
9. The motor can adopt a water jacket external circulation cooling system to ensure the safe operation of the electric pump in a dry state without water.
10. 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.

precautions

1: If this pump is used to pump thick and viscous slurry, the pump chamber needs to be cleaned to prevent sediment from being left inside the pump.
2: Do not operate the pump in a low head state for a long time to prevent overloading and motor burnout.
3: Never lift or suspend the cable or water pump.
4: Under normal conditions, the oil in the oil chamber (10-30 # oil) should be added or replaced every 300-500 hours of use to improve the service life of the mechanical seal. After 3000 hours of regular operation, the pump needs to be disassembled, inspected, and maintained. If necessary, vulnerable parts that are no longer suitable for use should be replaced.
5: When customers install automatic coupling devices, they need to determine the length of the guide rail (standard length is 3M).
