Product Application            
in order fo meet the sewage pump can be deposited in the bottom of the sewage sludge mixed into furbulent afterextractlon, so that the pump in the absence ot auxllary devices to achieve the function of high concentration.

Product Features                   

• Unique diving cable seal design: To prevent water from invading the motor through the cable core, epoxy resin directly seals with the stripped copper core of the cable to ensure no liquid infiltrates the motor through the cable. The wiring is of the plug - in type, quick, convenient, and reliable. However, the cable head must not come into contact with water, as water entering the cable will seriously reduce the insulation resistance of the motor, affecting its safety.
• The pump body and impeller adopt an optimal - matching high - efficiency hydraulic design. The impeller has a non - clogging structure, with excellent, stable, and mature performance, strong passing ability. The impeller has passed dynamic and static balance checks, resulting in small vibration and stable operation.
• Motor insulation class F, the enclosure protection level is IPX8. For motors with a power ≤ 7.5kW, a 105ºC thermal protector is installed inside the motor to ensure the water pump motor does not overheat and prevent equipment damage.
• The main shaft is designed with the shortest possible shaft extension structure, reducing deflection and vibration, and decreasing the load on the bearings, thereby prolonging the service life of the bearings.
• The shaft seal consists of two independent single - end - face mechanical seals, completely sealing and isolating the motor from the pump. Installed in a tandem arrangement, it provides double insurance, further improving the reliability of the seal and ensuring the long - term reliable operation of the pump.
• The oil chamber is embedded with a water - leakage signal sensor, which can continuously and effectively monitor the operating status of the pump. Preventive protection measures can be taken at an appropriate time to eliminate faults and ensure the pump's operation.
• The bearings are maintenance - free, capable of reliably bearing the radial and axial forces generated during the pump's operation, ensuring the correct position of the impeller in the volute, and having a long service life.
• The whole machine adopts a modular design. Each motor model can be matched with several pump head models, offering good versatility. The motor components are designed in a streamlined cylindrical shape, which is aesthetically pleasing and has low resistance.
• The standard materials for the pump body, motor shell, and impeller are grey cast iron parts. Special materials such as ductile iron, cast steel, and stainless steel are optional. The main shaft is martensitic stainless steel.
• With an automatic stirring function, it can stir the sediment in the sewage tank into a suspension, which is then sucked into the impeller flow channel and discharged. No manual cleaning is required, improving the anti - clogging and sewage - discharging capabilities of the submersible sewage pump. It completes the functions of drainage, cleaning, and desilting of the submersible sewage pump in one go, saving operation costs and being energy - saving and environmentally friendly.
• The installation system is universal and interchangeable with the second - generation WQ pump.
