Product Description

OVERVIEW

The ILG series vertical single-stage centrifugal pump is a high-efficiency, energy-saving product. It replaces traditional pumps like the SG, IS, and D types, offering flow rates from 1.5 to 1600 m³/h and heads from 5 to 150 m. The series includes various models, with materials and designs adjustable for different applications. It extends to the IRG, IHG, and YG pumps, making it versatile for multiple uses.

 

APPLICATION

The ILG vertical single-stage centrifugal pumps have a wide range of applications and are widely used in the following fields:

- Industrial and urban water supply and drainage
- Water supply for high-rise building pressure boosting
- Garden irrigation
- Firefighting pressure boosting
- Long-distance water delivery
- Heating and air conditioning circulation

 

ADVANTAGES

ILG vertical single-stage centrifugal pumps offer the following advantages

Compact Structure: Small in size, aesthetically pleasing, with a small installation footprint.
Easy Installation: The inlet and outlet diameters are the same and aligned on the same central line, eliminating the need to change the pipeline direction or redesign the pipeline.
Long Service Life: The pump operates smoothly with low noise and high component concentricity.
Excellent Sealing: The shaft seal uses wear-resistant materials such as hard alloy and silicon carbide for reliable, leak-free mechanical sealing.
Convenient Maintenance: Maintenance and repairs can be carried out without disassembling the pipeline-simply remove the pump cover nuts and take out the motor and transmission components.
Good Economy: The direct-coupled structure has a relatively low cost.
High Efficiency and Energy Saving: Equipped with a high-efficiency motor, the pump operates more efficiently and saves energy.

 

APPLICATION

1. ILG vertical single-stage Centrifugal Pumpsp: Designed for transporting clean water and other liquids with similar physical and chemical properties. It is suitable for industrial and urban water supply and drainage, high-rise building pressure boosting, garden irrigation, firefighting pressure boosting, long-distance water delivery, HVAC circulation, hot water circulation and pressure boosting in bathrooms, and equipment support. Operating temperature: T < 80°C.

2. IRG Vertical Hot Water (High-Temperature) Circulation Pump: Widely used in energy, metallurgy, chemical, textile, paper, and hotel boiler systems for high-temperature hot water pressure boosting and circulation, as well as in urban heating systems. The ILR model is suitable for use at temperatures T < 120°C.

3. IHG Vertical Pipeline Chemical Pump: Made of integrated stainless steel 304 (or 316, 316L) for transporting corrosive liquids (strong acids, strong bases) that are free of solid particles and have a viscosity similar to water. It is suitable for industries such as petroleum, chemicals, metallurgy, power, paper, food, pharmaceuticals, and synthetic fibers. Operating temperature: -20°C to 120°C.

4. YG Vertical Pipeline Oil Pump: Equipped with an explosion-proof motor with gas explosion-proof grades such as ExdIIBT4 and ExdIICT4. It is mainly used for transporting petroleum products such as gasoline, kerosene, and diesel. The medium being transported can be at temperatures ranging from -20°C to +120°C.
