• Pumping sewage water * The unique single or double vane impeller structure greatly improves the sewage passing capacity. Fibre with the length of 5 times the outlet can pass through, and solids up to half outlet can be effectively passed. * The mechanical seal adopts new hard corrosion-resistant material tungsten carbide and double face seal, which can make the pump operate safely and continuously for more than 8000 hours. * It has the advantages of compact structure, small size, low noise, remarkable energy-saving. It can work when submerged in the water and no need to build a pump house, which greatly reduces the project cost. * A high-precision anti-interference water leakage detection sensor is set in the sealing oil chamber, and a thermal sensor is embedded in the stator winding to automatically protect the motor. * According to the requirements of the users, it can be equipped with full-automatic control cabinet to automatically protect the water leakage, electric leakage, overload and overheat of the pump, so as to improve the safety and reliability of the pump. * The float switch can automatically control the start and stop of the pump according to the required liquid level change without special supervision, which is convenient to use. * WQ submersible sewage pump can be equipped with double guide rail auto-coupled installation system if the customer requires, which is convenient and simple for installation and maintenance. * Two different installation methods for choice, fixed auto-coupled installation system and mobile installation system.
