The main purpose of ISG vertical pipeline pump: 1. The ISG vertical pipeline centrifugal pump is used to transport clean water and other liquids with physical 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 pressurization, long-distance water supply, and heating , Bathrooms and other hot and cold water circulation pressurization and equipment matching, etc. Use temperature T<80℃. 2. IRG (GRG) vertical hot water (high temperature) hot water circulating pump, suitable for energy, metallurgy, wood processing, chemical industry, textile, papermaking, restaurants, bathrooms, hotels and other boiler hot water pressurized circulation transportation and urban heating For system circulation pumps, the temperature of the medium used by IRG does not exceed 120°C, and the temperature of medium used for GRG does not exceed 240°C. 3. IHG type vertical pipeline chemical pumps are used to transport liquids that do not contain solid particles, are corrosive, and have a viscosity similar to water. They are suitable for petroleum, chemical, metallurgical, electric power, paper, food, pharmaceutical and synthetic fiber sectors. It is -20℃~+120℃. 4. IHGB stainless steel explosion-proof chemical centrifugal pump is suitable for transporting flammable and explosive chemical liquids. 5. YG vertical pipeline oil pump is used to transport petroleum products such as gasoline, kerosene, diesel, etc. The temperature of the medium being transported is -20℃~+120℃. 6. ISGD, IRGD, GRGD, IHGD, YGD, IHGBD vertical low-speed centrifugal pumps are suitable for occasions with low environmental sound requirements and air conditioning cycles.
