Main models and scope of application of submersible sewage pump

Submersible sewage pumps mainly include: submersible sewage pumps mainly include: QW submersible sewage pumps, WQ fixed submersible 

sewage pumps with coupled submersible sewage pumps, JYWQ automatic stirring and uniform sewage pumps, JPWQ outsourcing stainless steel 

stirring and uniform sewage pumps, WQK/QG sewage pumps with cutting device, and AS tear-type submersible sewage pumps. The main materials 

are 201, 304, 316 stainless steel submersible sewage pumps, etc. According to the motor conditions, they can be divided into ordinary submersible 

sewage pumps and explosion-proof submersible sewage pumps.

The submersible sewage pump adopts a large runner anti-blocking hydraulic component design, which greatly improves the ability to pass through 

dirt and can effectively pass through 5 times the fiber substance of the pump diameter and solid particles with a diameter of about 50% of the pump 

diameter. Reasonable design, reasonable supporting motor, high efficiency and significant energy-saving effect. The mechanical seal adopts a 

double-channel series seal, and the material is hard wear-resistant tungsten carbide, which has the characteristics of durability and wear resistance, which 

can ensure the pump to run safely and continuously for more than 800 hours. The pump has a compact structure, small size, easy to move and easy to install. 

There is no need to build a pump room and can work by diving into the water, greatly reducing the cost of the project.

The QW mobile submersible sewage pump is compact in structure, small in size, easy to move and easy to install. There is no need to build a pump room, and 

can work by diving into the water, greatly reducing the cost of the project

When the WQ fixed-coupled submersible sewage pump needs to be lifted, people can do not need to go into the water and unscrew the screws, and directly lift 

the water pump. After maintenance, the water pump can be sealed with the pipes, so that the water pump can be operated normally. Small sewage pumps can be

 installed freely, while large sewage pumps are generally equipped with automatic coupling devices to be automatically installed, which is quite convenient to install 

and repair.

JYWQ/JPWQ automatic stirring and drainage pump uses an automatic stirring device based on ordinary sewage pumps. The device rotates with the motor shaft and

 generates extremely strong stirring force. It stirs the sediment in the sewage tank into suspended substances and is suctioned into the pump to discharge, improves 

the pump's anti-blocking and drainage capabilities, and completes drainage, cleansing and silting at one time, saving operating costs. It is an environmentally friendly 

product with obvious advanced and practicality.

The WQK/QG sewage pump with cutting device is the factory that absorbs advanced technology and processes in West Germany and develops the latest sewage

 discharge machine. It has particularly strong sewage discharge ability and good cutting performance. It can cut long fibers, plastics, paper, belts, cloth strips, straws, 

ropes and other impurities in the sewage and discharge them.

The AS tear-type submersible sewage pump is developed by our company using advanced technology from Germany's ABS company. This series of water pumps 

have a tear structure that can tear and cut off medium-length fibers, bags, belts, grass, cloth strips and other substances in sewage, and then discharge them smoothly. 

It is especially suitable for transporting liquids containing hard solids and fibers, as well as particularly dirty, sticky and slippery liquids.

These are the main types of submersible sewage pumps. The above only briefly introduces the usage and environment of each one. For detailed parameters, please
