The ISG series single-stage single suction vertical pipeline centrifugal pump adopts the performance parameters of the IS type centrifugal pump and is ingeniously combined and designed based on the general vertical pump. At the same time, hot water pumps, high-temperature corrosion-resistant chemical pumps, and oil pumps are derived according to different operating temperatures, media, etc. This series of products has the advantages of high efficiency, energy saving, low noise, and reliable performance.
2、 Scope of application:
1. ISG single-stage single suction pipeline centrifugal pump is used for conveying clean water and other liquids with physical and chemical properties similar to clean water. It is suitable for industrial and urban water supply and drainage, high-rise building pressurized water supply, garden sprinkler irrigation, fire pressure boosting, long-distance water supply, heating, bathroom and other cold and warm water circulation and pressure boosting equipment. The operating temperature is below 80 ℃.
2. The IRG type vertical hot water circulation pump is suitable for high-temperature hot water pressurized circulation and transportation in energy, metallurgy, chemical, textile, wood processing, papermaking, as well as boilers, bathrooms, hotels, and other areas, as well as for urban heating system circulation pumps. Its operating temperature is below 120 ℃.
3. IHG type vertical pipeline chemical pump is used for conveying liquids that do not contain solid particles, are corrosive, and have a viscosity similar to water. It is suitable for industries such as petroleum, chemical, metallurgical, power, papermaking, food, pharmaceuticals, and synthetic fibers, and can be used at temperatures ranging from -20 ℃ to 120 ℃.
4. Vertical pipeline oil pump, used for transporting petroleum products such as gasoline, kerosene, diesel, or flammable and explosive liquids, with a medium temperature of -20 ℃ -120 ℃.
5. ISG single-stage single suction pipeline centrifugal pump is suitable for occasions with low environmental noise requirements and air conditioning circulation.
3、 Product features:
1. The pump has a compact structure, small volume, and beautiful appearance, and its vertical structure determines a small installation footprint.
2. Easy to install, with the same inlet and outlet diameters and on the same centerline, without the need to change the pipeline.
3. The pump runs smoothly, with low noise and high component concentricity.
4. Reliable sealing and no leakage. The shaft seal adopts wear-resistant materials such as hard alloy and silicon carbide for mechanical sealing.
5. Easy to repair, no need to disassemble the pipeline, just remove the pump cover nut, take out the motor and transmission components for maintenance.
6. Its unique structure not only reduces the pump room area and improves space, but also greatly saves infrastructure investment.
