WQN series 315kW 150m³/h 425m high lift head head industrial submersible pump industrial wastewater treatment municipal water supply systems

The WQN series, a high-performance variant of the WQ series, is specifically designed for applications requiring ultra-high head performance. With a maximum rated head of 800 meters, it excels in challenging environments such as skyscraper water supply, mine dewatering, and industrial wastewater management. Its superior head capability, combined with energy efficiency, makes it ideal for demanding operations. Equipped with an intelligent control cabinet, the WQN series offers automated operation, simplifying maintenance and extending service life.

• Medium temperature ≤ 60℃,medium density <1200kg/m³,PH 4-10 .
• When used for pumping highly corrosive fluids or media with abrasive solid particles, the pump requires special customization.
• The diameter of solid particles in the medium should be less than 80% of the minimum flow passage dimension.
• The length of fibers in the medium should not exceed the diameter of the pump's discharge port.

• Non-explosion-proof scenarios in the chemical, petroleum, pharmaceutical, mining, papermaking, cement, steelmaking, power generation, coal processing industries, etc.
• Urban sewage treatment plant drainage systems, municipal engineering, etc.
• Suitable for the construction industry and others requiring the conveyance of sewage containing particulates, as well as for pumping clear water or liquids with corrosive properties.
• Ponds, fish ponds, or scenes where corrosive liquids such as seawater and chemical wastewater need to be pumped.

• The flow parts adopts a lower support structure, combined with a multi-stage impeller arrangement, ensuring that the pump meets the requirements for high head and large flow under various installation conditions.
• Made of hard cast iron, and the flow parts adopt QBQ surface treatment process, which has excellent wear resistance and corrosion resistance.
• The mechanical seals have high-pressure resistance,which enables pumps to submerged deeper. the pump equipped with cooling jacket,could not fully submerged in the medium.the flow parts below the motor,water cooling the motor during the operation,extending service life and enabling work at the low water level.
• The design of the top outlet is more space saving.
• The motor is optional with overheat protection.
• There is a pressure relief hole on the pump,which could release the pressure exerted by the medium on the shaft seal.

FAQ
