Product Overview
The ISW series single-stage, single-suction pipeline centrifugal pumps are developed by adopting and further enhancing the performance parameters of the IS-type pumps. This innovative design successfully addresses several drawbacks commonly encountered in IS-type pumps. Featuring high efficiency, energy savings, low noise levels, stable performance, and easy maintenance, the ISW series represents the ideal next-generation replacement for IS pumps. Additionally, depending on the specific temperature requirements, the series includes specialized models such as hot-water pumps, high-temperature pumps, corrosion-resistant pumps, and oil pumps. All products are designed and manufactured according to the international ISO 2858 standard and meet the stringent quality standards outlined in the national Ministry of Machinery’s JB/T 53058-93R specification. Notably, these pumps passed the rigorous inspection conducted by the National Ministry of Machinery’s management system certification process in 1993.
Uses
1. The ISW horizontal pipeline pump is designed for conveying clean water and other liquids with physical and chemical properties similar to water, making it suitable for industrial and municipal water supply and drainage systems, boosting water pressure in high-rise buildings, irrigation in landscaping projects, fire protection boosting, long-distance water transportation, HVAC and refrigeration circulation systems, as well as circulating and pressurizing hot and cold water in applications like bathrooms and equipment integration. The pump is ideal for use at temperatures up to T < 80°C.
2. The IRW (GRW) horizontal pipeline hot water (high-temperature) circulating pumps are widely suitable for applications including boilers in industries such as energy, metallurgy, chemical processing, textiles, and paper manufacturing, as well as hotels and restaurants—specifically for boosting and circulating high-temperature hot water and serving urban heating systems. The IRG model is designed for use at temperatures below 120°C, while the GRG model can handle temperatures up to 240°C.
3. The IHW horizontal chemical process pump is designed for transferring liquids that are free of solid particles, highly corrosive, and have a viscosity similar to water. It is ideal for applications in industries such as petroleum, chemical processing, metallurgy, power generation, paper production, food & pharmaceuticals, and synthetic fibers, with an operating temperature range of -20°C to 120°C.
4. ISWB horizontal explosion-proof oil pump, designed for transferring petroleum products such as gasoline, kerosene, and diesel fuel, with a medium temperature range of -20°C to +120°C.
Working conditions
1. The pump system’s maximum working pressure is 1.6 MPa, meaning the pump suction inlet pressure plus the pump head must not exceed 1.6 MPa. (If the pump system’s working pressure exceeds 1.6 MPa, please specify this requirement at the time of order so that special steel materials can be used for the pump’s flow passages and connecting components during manufacturing.)
2. The medium to be conveyed is clean water or other fluids with physicochemical properties similar to water. (If the medium contains fine particles, please specify separately at the time of ordering to enable the installation of a wear-resistant mechanical seal.)
3. Ambient temperature not exceeding 40°C, with relative humidity no higher than 95%.

- Product Description

Product Overview
The ISW series single-stage, single-suction pipeline centrifugal pumps are developed by adopting and further enhancing the performance parameters of the IS-type pumps. This innovative design successfully addresses several drawbacks commonly encountered in IS-type pumps. Featuring high efficiency, energy savings, low noise levels, stable performance, and easy maintenance, the ISW series represents the ideal next-generation replacement for IS pumps. Additionally, depending on the specific temperature requirements, the series includes specialized models such as hot-water pumps, high-temperature pumps, corrosion-resistant pumps, and oil pumps. All products are designed and manufactured according to the international ISO 2858 standard and meet the stringent quality standards outlined in the national Ministry of Machinery’s JB/T 53058-93R specification. Notably, these pumps passed the rigorous inspection conducted by the National Ministry of Machinery’s management system certification process in 1993.
Uses
1. The ISW horizontal pipeline pump is designed for conveying clean water and other liquids with physical and chemical properties similar to water, making it suitable for industrial and municipal water supply and drainage systems, boosting water pressure in high-rise buildings, irrigation in landscaping projects, fire protection boosting, long-distance water transportation, HVAC and refrigeration circulation systems, as well as circulating and pressurizing hot and cold water in applications like bathrooms and equipment integration. The pump is ideal for use at temperatures up to T < 80°C.
2. The IRW (GRW) horizontal pipeline hot water (high-temperature) circulating pumps are widely suitable for applications including boilers in industries such as energy, metallurgy, chemical processing, textiles, and paper manufacturing, as well as hotels and restaurants—specifically for boosting and circulating high-temperature hot water and serving urban heating systems. The IRG model is designed for use at temperatures below 120°C, while the GRG model can handle temperatures up to 240°C.
3. The IHW horizontal chemical process pump is designed for transferring liquids that are free of solid particles, highly corrosive, and have a viscosity similar to water. It is ideal for applications in industries such as petroleum, chemical processing, metallurgy, power generation, paper production, food & pharmaceuticals, and synthetic fibers, with an operating temperature range of -20°C to 120°C.
4. ISWB horizontal explosion-proof oil pump, designed for transferring petroleum products such as gasoline, kerosene, and diesel fuel, with a medium temperature range of -20°C to +120°C.
Working conditions
1. The pump system’s maximum working pressure is 1.6 MPa, meaning the pump suction inlet pressure plus the pump head must not exceed 1.6 MPa. (If the pump system’s working pressure exceeds 1.6 MPa, please specify this requirement at the time of order so that special steel materials can be used for the pump’s flow passages and connecting components during manufacturing.)
2. The medium to be conveyed is clean water or other fluids with physicochemical properties similar to water. (If the medium contains fine particles, please specify separately at the time of ordering to enable the installation of a wear-resistant mechanical seal.)
3. Ambient temperature not exceeding 40°C, with relative humidity no higher than 95%.
