1. transmission of water, slurry, sewage with solids of sand, gravel, continuous fibres.
2. sand suction and sewage treatment for municipal works, industry, hospital, construction, hotel, etc.
3. well in circumstances with corrosive and abrasive medium.
1.Mechanical seal of tungsten carbide, silicon carbide and hard alloy materials avoids the water entering the motor.
2. Auxiliary impeller applies to balance outer pressure of the oil cavity and prolong the motor`s service life.
3. Unique wide flow-channel design ensures the pump has powerful passing capacity and will not easily be silted or intertwined.
4. Can work normally even in low water level, since over 18.5kw power pumps cool off with outer circulating water automatically.

The main purpose:
WQ sewage submersible pump is mainly used in chemical, petroleum, pharmaceutical, mining, paper industry, cement plant, steel plant, power plant, coal processing industry, and urban sewage treatment plant drainage system, municipal engineering, construction sites and other industries conveyor belt Granules, sewage, dirt, can also be used to pumping water and corrosive media with high efficiency, energy saving, anti-winding, no clogging, high reliability. The flow range of 15-100 cubic meters / hour, the lift range of 10-50 meters.
1. If the pump is used to suck thicker than the viscosity of the slurry, the need to clean the pump chamber to prevent the pump to leave sediment.
2. Do not lift or suspend the cable.
3. The pump should not be long-term low-lift operation in the state, to prevent overload and burn out the motor.
4. When the customer is equipped with automatic coupling device, the length of guide rail should be determined (standard length is 3M).
5. Under normal conditions, every 300-500 hours should be added or replaced oil in the oil room (10-30 # oil), to improve the service life of mechanical seals. Pump routine operation after 3000 hours, the need for the pump for inspection and maintenance, if necessary, replace the wearing parts should not be reused.
Conditions of Use:
Medium temperature does not exceed 60 ℃, the severity of 1.0 ~ 1.3kg / dm3, PH value in the range of 5 to 9. The pump is mainly made of cast iron and can not be used for pumping highly corrosive liquids. Pump work, the motor part of the exposed surface shall not exceed 1 / 2.1Cr18Ni9Ti stainless steel can use a variety of corrosive media.
