ISW series horizontal centrifugal pumps
introductions
ISW, ISWR, ISWH, ISWD, ISWRD, ISWHD, ISWYD series horizontal single stage signle suction centrifugal pump is a energy-saving product that designed and manufactured according to ISO2858 and JB/T53058-93. This pump adopts domestic advanced hydraulic model optimization design. Meanwhile according to the differences of temperature, medium based on ISW to derive hot water pump, high temperature pump, Centrifugal Pump, oil pump, etc., is the national standard finalize promoted product.
features
Absolute concentricity of pump shaft and excellent static and dynamic balance of impeller ensure smooth operation, no vibration, different material cemented carbide sealing ensures the different media transmission without leakage, simple and reasonable structure, key part adopts the international first-class quality mating, machine trouble-free working time is greatly increased. Easy maintenance, replacement of sealing and bearing is easy. Series flow range 1.5 ~ 2000m3 / h, head range: 5 ~ 125m
usages
（1) ISW type horizontal centrifugal pump is used for conveying water, chemical and physical properties and the other similar liquids, used in industrial and urban water supply and drainage, high buildings pressurized water, garden sprinkling irrigation, fire protection surpercharge, distant distance transportation, HVAC refrigeration circulation, cold and hot water circulation pressurization and equipment, using temperature < 80℃. (2) ISWR horizontal hot water pump is widely used in metallurgical, chemical, textile, paper and hotel and urban water circulation pressurization boiler heating system, using temperature ≤120℃. (3) ISWH horizontal Centrifugal Pump is used for conveying the liquids that excluding solid particles, corrosive, viscosity similar to water, used in petroleum, chemical, metallurgy, electric power, papermaking, foodstuff, pharmacy and synthetic fiber and other departments, using temperature -20¬¬－120℃. (4) ISWB horizontal pipeline oil pump is suitable for conveying oil, kerosene, diesel oil, oil products or inflammable and explosive liquids, medium temperature is - 20-120 degrees
