37kw Durable High Head Submersible Pump For Boreholes, Irrigation, And Municipal Water Systems Water Pumps With High Suction Head

Engineered for efficiency and durability, the WQN submersible sewage pump is perfect for industries like chemical processing, mining, paper manufacturing, and municipal wastewater management. It handles a wide range of liquids, including clear water, sludge, and corrosive fluids, making it suitable for aquaculture and industrial wastewater treatment. The pump’s multi-stage impeller design ensures high head and large flow rates, while the robust cast iron construction and specialized surface treatment guarantee long-term reliability. With a top discharge design and water-cooled motor, it operates safely even when partially submerged. Custom options are available for highly abrasive or corrosive media. Suitable for temperatures ≤60°C and pH 4-10.

• 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.
