Qw200-250-15-18.5 Wq Type Non-Clogging Submersible Sewage Lift Pump Made of Cast Iron and Stainless Steel

QW200-250-15-18.5  WQ type non-clogging submersible sewage lift pump made of cast iron and stainless steel
QW submersible sewage pumps are suitable for the discharge of severely polluted wastewater from factories and businesses, sewage discharge stations in residential areas, urban sewage treatment plant drainage systems, civil air defense system drainage stations, water condensation devices in water plants, sewage discharge in hospitals and hotels, and municipal engineering buildings. It is used in industries such as construction sites, exploration, mining supporting machines, rural biogas pools, farmland irrigation and other industries to convey granular sewage and dirt. It can also be used for clean water and corrosive media.

QW/WQ 25-7-8-0.55  220V 60HZ  sewage sump pump sewage pump system septic tank pump:

QW submersible sewage pumps are suitable for the discharge of severely polluted wastewater from factories and businesses, sewage discharge stations in residential areas, urban sewage treatment plant drainage systems,
The QW/WQ submersible sewage pump has a compact structure, small size, easy movement and installation. There is no need to build a pump room and it can work when submerged in water, which greatly reduces the project cost. QW submersible sewage pumps have various structures and installation methods, simplifying the pumping station and saving investment. The motor is separated by an oil chamber, which has no clogging and significant energy saving. It is a new generation product of my country's pumps. Commonly used models are: QW50-20-7-0.75, QW25-8-22-1.1, QW50-10-10-0.75, QW50-20-15-1.5, QW50-15-25-2.2, QW50-18-30- 3.

Principles for selecting sewage pumps - DFIN Pump Industry

1. High mechanical reliability, low noise, and minimal vibration.

2. Economically, it is necessary to comprehensively consider the total cost of equipment, operation, maintenance, and management fees to minimize them.

3. Make the selected pump type and performance meet the requirements of process parameters such as device flow rate, head, pressure, temperature, cavitation flow rate, and suction stroke.

4. Must meet the requirements of medium characteristics.

For pumps that transport flammable, explosive, toxic, or valuable media, reliable shaft seals or leak free pumps are required, such as magnetic drive pumps, diaphragm pumps, and shielded pumps

For pumps transporting corrosive media, it is required that the convection components use corrosion-resistant materials, such as AFB stainless steel corrosion-resistant pumps and CQF engineering plastic magnetic drive pumps.

For pumps transporting media containing solid particles, it is required that the convection components be made of wear-resistant materials, and if necessary, the shaft seal should be flushed with clean liquid.
