QW submersible sewage pump With coupler is a new generation pump product successfully combined foreign advanced technology with domestic water pumps' features.
It has the unique features of perfect energy-saving effects,anti-entanglement, non-blocking, automatic installation and automatic control.
Moreover, It also has a unique effect in discharging solid particles and long-fiber sewage.
This kind of pump adopts a unique single / double channel impeller structure and a new type of mechanical seal, which can effectively transport solids particles and long fibers.
According to different working conditions, there are two installation methods, fixed automatic coupling installation and moveable installation freely.
Application Scope
The pump can be widely used in the areas of Chemical, Petroleum, Mining, Paper Industry, Pharmaceutical Industry,Cement Plant，Steel Plant，Power Plant，Coal Processing Industry and Sewage Discharge from Municipal Sewage Treatment Plant, Municipal Engineering and Construction Sites, etc. Moreover it also can be used for Clean Water and corrosive Medium.
Product Features
1. QW submersible sewage pump adopts unique single / double vanes impeller structure, thus improving the passing ability of dirty products of the fibre length which 5 times of the pump’s outlet diameter and the solid particles of 50% of the pump outlet diameter.
2. The mechanical seal adopts a new type of hard corrosion resistant tungsten carbide, so that the pump can operate safely and continuously over 8000 hours.
3. The pump has compact structure, small volume, low noise, perfect energy saving effect, convenient for maintenance, and the pump doesn’t need to build a pump room, it can work directly when submerging in the water, which has greatly reduced the project costs.
4.The pump’s sealed oil chamber has installed a high precision anti-interference water leakage detection sensor, and thermal elements are embedded in the stator winding, which is a great automatically protection for the pump motor.
5. It can be equipped with a fully automatic control cabinet according to different users need, which is a great automatic protection for water leakage, electric leakage, overloaded and over-temperature and improves the product safety and reliability.
6. The float switch can automatically control the start and stop of the pump according to the required liquid level. It does not need to be supervised by a special person, and it is extremely convenient to use.
7.According to different users need, QW submersible sewage pump can be equipped with the installation system of double guide coupling rail automatic, it brings convenience for installation and maintenance, and people don’t need to enter the sewage sump.
8. It can be used on all the heads scope of the pump and ensure the motor is not be overloaded.
9. There are two different installation methods, fixed automatic coupling installation system and moveable installation freely.
