Applications
1. ISWH horizontal chemical centrifugal pump is suitable for conveying corrosive liquids in industries such as petroleum, chemical, metallurgy, electric power, papermaking, food, pharmaceutical, and synthetic fiber. Operating temperature: -20℃ to +105℃.
2. ISW horizontal 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 pressurization, marine use, garden sprinkler irrigation, fire protection pressurization, long-distance transmission, HVAC refrigeration circulation, bathroom and other hot/cold water circulation, and equipment matching. The medium temperature should not exceed 85℃.
3. ISWR horizontal hot water circulation pump is suitable for energy, metallurgy, wood processing, chemical, textile, papermaking, as well as hotels, bathrooms, guesthouses, boiler hot water pressurization circulation, and urban residential heating circulation. The operating temperature should not exceed 120℃.
4. ISWY horizontal explosion-proof oil pump is suitable for conveying flammable and explosive liquids in petroleum, textile, chemical, and machinery industries. The medium temperature should not exceed 120℃.
5. ISWHY horizontal stainless steel explosion-proof chemical centrifugal pump is suitable for conveying flammable and explosive chemical liquids.
6. ISWD, ISWRD, ISWHD, ISWYD, and ISWHYD horizontal low-speed centrifugal pumps are suitable for occasions with high environmental noise requirements, especially for chilled water, cooling water circulation, and terminal pressurization in air conditioning systems.
Working Conditions:
1. The maximum working pressure of the pump system is 1.6MPa, i.e., pump suction pressure + pump head ≤1.6MPa (if the working pressure of the pump system exceeds 1.6MPa, it should be specified separately when ordering so that the pump's flow components and connecting parts can be made of cast steel during manufacturing.
2. The auxiliary medium is clean water or other liquids with physical and chemical properties similar to clean water (if the conveyed medium contains fine particles, it should be specified separately when ordering so that wear-resistant mechanical seals can be assembled). The volume content of solid particles in the conveyed medium should not exceed 0.1% of the unit volume, with a particle size <0.2mm.
3. The ambient temperature should not exceed 40℃, altitude should not exceed 1000m, and relative humidity should not exceed 95%.
Note: If the medium contains fine particles, please specify it when ordering so that the manufacturer can adopt wear-resistant mechanical seals.
Product Features:
1. Compact structure. This series of pumps has a horizontal structure, integrating the pump and motor, with an attractive appearance and small footprint. Compared with ordinary horizontal pumps, the floor space is reduced by 30%. If an IP54 outdoor motor is used, no pump house is needed, and it can be placed outdoors.
2. Stable operation, low noise, and high component concentricity. The motor and pump are directly connected, simplifying the intermediate structure and increasing operational stability. The impeller has excellent dynamic and static balance, with no vibration and low noise during operation, extending bearing life and improving the working environment.
3. The shaft seal uses high-quality mechanical seals. The rotating and stationary rings are made of cemented carbide, which is wear-resistant, leak-free, and has a long service life.
4. Advanced hydraulic models are adopted, featuring high efficiency and good performance.
5. Unique structure. A drain hole is provided at the lower side of the pump body, and pressure tapping holes are provided on the inlet and outlet flanges to ensure normal operation and maintenance of the pump.
6. The inlet of this series of horizontal pumps is horizontal, and the outlet is vertically upward, facilitating pipeline layout.
