90kw 220m³/h flow 70m WQ series industrial submersible electric pump pumping chemical wastewater dewatering pump sewage pump 380Vsewage discharge agricultural irrigation drainage

WQ220-70-90 refers to a 220m³/h, 70m head, 90kw submersible sewage pump, which can be used for industrial wastewater treatment, municipal water supply systems, agricultural irrigation, construction sites, fire drainage systems, seawater treatment, etc.

• Voltage: 380/660V,660/1140V,400V,440V,460V, customizable options are available.
• Medium: Temperature not exceeding 60°C, PH 4-10, medium density ≤ 1200 kg/m³.(Customizable for special requirements).
• Submersion depth: ≤20m.
• 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.

• Applicable to 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 adopt QBQ surface treatment process, which has excellent wear and corrosion resistance.
• The thickened impeller, pump body, and pump cover effectively extend the service life of the components.
• Suitable for long-term use in environments with corrosive liquids and abrasive particles (such as sediments and gravel).
• The bottom inlet and bottom outlet design ensures strong clogging resistance and high flow capacity, making it suitable for a wider range of applications.
• Simple strcuture, lightweight, easy to install and maintain.

FAQ
