Sewage pump selection Main classification of sewage pumps

The main models of sewage pumps include QW, WQ, JYWQ, JPWQ, WQK/QG, AS/AV, GW, LW, ZW and other series. The following will 

introduce them to you one by one.

1. QW submersible sewage pump:

The QW submersible sewage pump has a reasonable design, reasonable supporting motor, high efficiency, and significant energy-saving 

effect. It is developed by introducing advanced experience in foreign high-efficiency, energy-saving, non-blocking sewage pumps, combined

 with the technical strength of this unit, and all performance indicators have reached the level of similar products in the national standard. 

Because of the unique single-channel impeller and dynamic seal, we use two sets of special materials, cemented carbide mechanical sealing

 devices. The motor is separated by an oil chamber, which has no blockage, high efficiency and significant energy saving. It is the latest product 

for the renewal of pumps in my country and is highly popular and well-received by users. The main difference between QW submersible sewage 

pump and WQ submersible sewage pump is the installation method, and the QW submersible sewage pump is a mobile installation.

The WQ submersible sewage pump is equipped with coupling device, which is a fixed installation. The advantage over the QW submersible 

sewage pump is mainly fixed and convenient maintenance. The sewage pump will slide up along the track of the self-drift. (It is generally used

 in daily use, septic tanks, or domestic sewage tanks) In this way, people don’t have to go down to the dirty sewage tank for repair.

2. JYWQ/JPWQ automatic stirring and discharge pump

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, and is an environmentally friendly product with obvious advanced and practicality.

JYWQ/JPWQ automatic stirring and sewage pump has a stirring function and is suitable for sediment. Of course, there are too many specific functions. 

JYWQ is an automatic stirring and sewage pump, and JPWQ is an outsourcing stainless steel stirring and sewage pump.

3. WQK/QG sewage pump with cutting device

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 WQK/QG sewage pump with cutting device is particularly suitable for narrow operating surfaces such as shipbuilding, communications, shipping,

 basements, and excavation of ponds to dredge river channels, especially individual food processing fields, individual farms, drilling industry, water pit 

wells, paper mills, and paint factories. The sewage pump with cutting device is mainly used to discharge domestic wastewater, sewage, human feces and 

urine, solid suspensions containing short fiber scraps, wood chips, starch, sediment, ore particles and non-corrosive media. The temperature of the liquid 

being pumped shall not exceed 40℃, the density shall not exceed 1200kg/m3, and the pH value shall not be 9. The electric pump adopts double-end 

mechanical sealing and rotating impeller. The impeller is made of stainless steel, wear-resistant, non-blocking, non-wrapped, and has the advantages 

of small size, compact structure and convenient portability.

4. AS/AV tear-type submersible sewage pump

Compared with WQK/QG sewage pump with cutting device, the scope of application is relatively small. The maximum AS/AV motor is generally 7.5KW, 

while the WQK/QG sewage pump with cutting device can reach 160KW or even larger.

The AS/AV tear submersible sewage pumps are all equipped with adjusted tearing mechanisms, which can tear and discharge medium-length fibers, 

bags, belts, grass, cloth strips, etc. in the sewage and then discharge them. Therefore, working in sewage will not be blocked and the operation will be 

extremely reliable. The AS cutting submersible sewage pump adopts the advanced technology of Germany's ABS company, which is particularly suitable

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

The main ones are these, and according to the different materials, they are divided into many types, 201 stainless steel. 304 stainless steel, 316 stainless 

steel. GW, LW, and ZW are mainly used on water, which has a completely different use environment and effect from the above. Next time, Dingfei Pump 

Industry Technology will take you to learn more about the main performance and uses of these sewage pumps.
