ISG pipeline centrifugal pump Introduction: ISG series single stage single suction vertical centrifugal pump is designed with reference to the performance parameters of the Company under the international ISO2858 and national standard JB / T6878.2-93, combined with the company many years of experience in the production of second-generation energy-efficient products is an alternative type of pipe centrifugal SG, IS-type centrifugal pump, D-type multi-stage centrifugal pumps ideal for other conventional products. Series Flow range 1.5 ~ 1600m3 / h, head range 5 ~ 156m, diameter: 15 ~ 500mm, basic type, shunt type, cut type, and other specifications. According to different media and different temperature, the material and structural changes in the flow part of the design and manufacture of the same parameters of the IRG-type heat pumps, IHG-type pipe chemical pump, YG vertical pipeline pump, so that the series gained popularity, complete You can replace conventional centrifugal pumps used in all cases. ISG pipeline centrifugal pump features: ① pump for the vertical structure, import and export of the same caliber, and in the same center line, as the valve can be installed in the pipeline among the compact appearance, small footprint, construction investment is low, such as plus protective cover can be placed outdoors. ② impeller mounted directly on the motor shaft extension, the short axial dimension, compact structure, reasonable configuration of pump and motor bearings, can effectively balance the radial and axial loads generated by operation of the pump, thus ensuring the smooth operation of the pump, vibration very low noise. ③ seal with mechanical seal or a combination of mechanical, using imported titanium alloy seal ring, medium and high temperature mechanical seal with carbide only quality, wear-resistant seal, can effectively increase the mechanical seal life. ④ installation and maintenance of instant noodles, no need to open pipeline system, only remove the pump nut seat body out all the rotor components. ⑤ flow and head requirements that need the use pumps in series or parallel operation according to the requirement. ⑥ can use vertical and horizontal pumps installed according to requirements of piping layout. ISG pipeline centrifugal pump use: 1, ISG vertical centrifugal pump for conveying water and other liquids with similar physical properties of water, the use of medium temperature does not exceed 80 ℃, suitable for industrial and urban water supply and drainage, high-rise building pressurized water, garden irrigation, fire booster, long-distance water, heating, bathrooms and other warm and cold pressurized water cycle and other ancillary equipment. 2, IRG vertical hot water circulating pump for energy, metallurgy, wood processing, chemicals, textiles, paper and restaurants, bathrooms, hotels and other boilers, circulation of urban heating system circulating pump is not used, the use of medium temperature超过 120 ℃. 3, IHG vertical chemical pumps for textile, petroleum, chemical, pharmaceutical, health, food, oil refineries and other industrial chemical transport corrosive liquids, medium temperature of -20 ℃ ~ + 120 ℃. 4, YG vertical pipeline oil transport gasoline, kerosene, diesel and other petroleum products are transported medium temperature of -20 ℃ ~ + 120 ℃. ISG pipeline centrifugal pump performance parameters: for example: ISG50-160-3 (I) AB ISG- 50- vertical centrifugal pump inlet and outlet nominal diameter (mm) 160- nominal impeller diameter (mm) 3- power I- traffic classification A B- impeller first, second cut
