QW (WQ) submersible sewage pump
The QW (WQ) submersible sewage pump adopts a unique single-blade or double-blade impeller structure, which greatly improves the sewage passing capacity and can effectively pass fibrous materials 5 times the pump diameter and solid particles with a diameter of about 50% of the pump diameter. The mechanical seal adopts a new hard and corrosion-resistant titanium tungsten material, which can make the pump run safely and continuously for more than 8,000 hours. The overall structure is compact, small in size, low in noise, and has significant energy-saving effects. It is easy to repair and maintenance. There is no need to build a pump room. It can work by submerging in water, which greatly reduces the project cost.
For example: 40QW(WQ)15-30-2.2
40-caliber (mm)
QW(WQ)-submersible sewage pump
15-flow rate (m3/h)
30-lift (m)
2.2-motor power (kw)
It is suitable for conveying sewage and dirt with particles in industries such as chemical, petroleum, pharmaceutical, mining, papermaking, cement plants, steel mills, power plants, coal processing industries, as well as drainage systems of urban sewage treatment plants, municipal engineering, construction sites, etc. It is also used to pump clean water and corrosive media.
