Product Introduction

The WQ type engineering sewage pump is a new generation of pump products developed based on the introduction of advanced foreign technology and combined with the characteristics of domestic water pump usage. It has significant energy-saving effects, anti entanglement, no blockage, automatic installation and automatic control. It has a unique effect in the discharge of solid particles and long fiber waste.
The engineering sewage pump adopts a unique structure and a new type of mechanical seal, which can effectively transport solid substances and long fibers. Compared with traditional impellers, the impeller of this pump adopts a single channel or double channel form, which is similar to a curved pipe with the same cross-sectional size and has very good flow characteristics. Coupled with a reasonable volute chamber, the pump has high efficiency and the impeller has undergone dynamic and static balance tests, making the pump operate without vibration.

Product Features

1. The overall structure is compact, the volume is small, the noise is low, and the energy-saving effect is significant. It is easy to maintain and does not require the construction of a pump room. It can work underwater, greatly reducing the project cost.
2. The float switch can automatically control the start and stop of the pump according to the required liquid level changes, without the need for special supervision, making it extremely convenient to use.
3. By adopting a unique single or double blade impeller structure, the ability of pollutants to pass through is greatly improved, which can effectively pass through fiber materials with a diameter of 5 times the pump diameter and solid particles with a diameter of about 50% of the pump diameter.
4. It can be used within the full head without overloading the motor.
5. The mechanical seal adopts a new type of hard and corrosion-resistant titanium tungsten material, which can ensure the safe and continuous operation of the pump for more than 8000 hours.
6. The pump is equipped with a high-precision anti-interference water leakage detection sensor in the sealed oil chamber, and a thermal sensor is embedded in the stator winding to automatically protect the water pump motor.
7. The engineering sewage pump can be equipped with a dual rail automatic coupling installation system according to user needs, which brings greater convenience to installation and maintenance, and people do not have to enter the sewage pit for this.
8. There are two different installation methods, fixed automatic coupling installation system and mobile free installation.
9. A fully automatic control cabinet can be equipped according to user needs to automatically protect the pump from water leakage, electric leakage, overload, and overheating, improving the safety and reliability of the product.
There are many manufacturers of WQ type engineering sewage pumps on the market now, which one is good for engineering sewage pumps? Dadonghai Pump Industry specializes in producing engineering sewage pumpsHigh temperature resistant sewage pumpThe models are very complete. Welcome everyone to consult and purchase (WQ sewage pump performance parameter table, follow here).

Product Usage

The WQ type engineering sewage pump is suitable for conveying granular sewage and waste in industries such as chemical, petroleum, pharmaceutical, mining, paper industry, cement plant, steel plant, power plant, coal processing industry, as well as urban sewage treatment plant drainage system, municipal engineering, construction sites, etc. It can also be used for clean water and slightly corrosive media.
