sewage submersible pump for sewage plant and drainage

The basic working principle of the sewage submersible pump is to rotate the pump impeller driven by an electric motor, so that the water flows through the pump body and is discharged through the outlet. As the pump body is designed as submersible, its motor and pump body are completely sealed and can be directly immersed in the liquid to work. This design not only saves space, but also improves the working efficiency of the pump. The motor is connected to the pump impeller through the shaft, and the power generated by the motor is transferred to the impeller through the rotating shaft, and the centrifugal force generated by the rotation of the impeller pushes the sewage or wastewater to the outlet to complete the discharge task.

sewage submersible pump features:

1. Sturdy and durable materials:
   • Cast iron pump body: the pump body is made of cast iron and undergoes special anti-rust treatment, which has strong corrosion and abrasion resistance, and is able to operate for a long time in harsh environments.
   • High-strength cast iron heat-treated impeller: the impeller is heat-treated with good abrasion resistance and strength, which ensures that the pump is not easily damaged when dealing with sewage with high impurities.
   • AISI304 stainless steel fittings: The water contact parts of the pump are made of AISI304 stainless steel, which further improves the corrosion resistance and service life.
2. High-efficiency sealing system:
   • German technology mechanical seal: German advanced mechanical seal technology is adopted to ensure good sealing inside the pump body, preventing sewage leakage and reducing maintenance costs.
   • Taiwan imported “O” ring: Imported “O” ring provides excellent sealing performance and further improves the working stability of the pump.
3. Powerful motor:
   • Silent bearing: The motor is equipped with silent bearing to reduce the noise during operation, suitable for use in densely populated areas.
   • Copper wire motor: the use of copper wire motor provides higher motor efficiency and longer service life.
   • Stator and Rotor National Standard Cold Rolled Silicon Steel Sheet: High standard cold rolled silicon steel sheet is used to improve the energy efficiency of the motor and reduce energy loss.
   • Built-in thermal protection device: The motor has a built-in thermal protection device, which automatically protects and resets the motor when the temperature of the motor is too high, ensuring the safe operation of the pump.
4. Protection design:
   • Insulation class: F: The motor adopts F class insulation, which can withstand higher temperature working environment.
   • Protection grade: IPX8: With IPX8 waterproof grade, the motor can be immersed in water for a long time, applicable to a variety of environments where the water level changes.
5. Adapt to a wide range of voltage:
   • Voltage use range: 160-230V/50Hz, 340-410V/50Hz, suitable for power systems in different areas, able to start and run stably.
   • Low voltage start: 120V low voltage start design, to ensure that the electric pump can work stably in areas with large voltage fluctuations.

Sewage submersible pumps are widely used in the following areas:

1. Industrial Sewage Discharge: It is suitable for sewage wastewater discharge in factories, manufacturing industries and other places to deal with sewage containing oil, chemical waste or other impurities.
2. Commercial and Municipal Drainage System: It can be used for sewage discharge in hotels, hospitals, commercial buildings and so on.
3. Urban sewage treatment plant: In urban sewage treatment plant, sewage submersible pumps are used for sewage collection, transportation and treatment.
4. Residential area and human defense system: drainage of residential area or underground human defense system to prevent sewage and stagnant water pollution.
5. Agriculture and rural applications: suitable for rural biogas digesters, farmland irrigation, river and pond dredging, etc., can effectively discharge sewage and wastewater.
6. Construction site: sewage discharge on the site, especially sewage containing sediment or other solid particles generated during construction.
7. Mines and power plants supporting: mines, power plants and other places that need to deal with large amounts of wastewater and sewage, sewage submersible pumps provide efficient drainage solutions.
