Industrial Grundfos Centrifugal Pump Factory – ISG, YG, TPLB, TPBL, ISW Pipeline Centrifugal Pump Series – State Machinery Equipment Manufacturing

Product Introduction

ISG series single-stage single-suction vertical pipeline centrifugal pump is the second generation of high-efficiency energy-saving product designed by our company based on many years of production experience as per the performance parameters stated in the international standard ISO2858 and the national standard JB/T6878.2-93. It is an ideal substitute for normal pumps like SG pipeline, IS and D multi-stage centrifugal pumps. This series has a flow range of 1.5~1600m/h and a lift head. range of5~ 125m, which includes many specifications like basic, diversion and cutting types. According to the differences in working medium and temperature as well as material and structural changes of the flow-through part, it can be designed and manufactured into IRG hot water pump, IHG pipeline chemical pump and YG pipeline oil pump with the same performance parameters. Accordingly, this series can be widely applied to replace the normal centrifugal pump completely to be used in all cases.

Working Conditions

1. Suction pressure ≤1.0MPa, or the maximum working pressure of pump system ≤1.6MPa,namely pump suction pressure + pump delivery head ≤1.6MPa, pump static test pressure at 2.5MPa. Please specify the working pressure of the system when placing an order. To acquire working pressure of pump system greater than 16MPa should be specified separately when placing an order for our convenience to use cast steel for wetted parts and connection parts in production.
2. Ambient temperature < 40℃, relative humidity <95%.
3.Volume content of solid particles in medium to be delivered shouldn’t exceed 0. 1% of unit volume, granularity <0.2mm.
Note: to handle medium carrying small particles, please specify when placing an order for our convenience to use wear resistant mechanical seal.

Main Purpose

1. ISG vertical centrifugal pump is used to transport clear water or other liquids with similar physical and chemical properties as clear water, with a working medium temperature less than 80℃ ,which is applicable for industrial and urban water supply and drainage, pressurization and water supply for high-rise, sprinkling irrigation for garden, pressurization for fire control, long-distance water supply, pressurization of cold and hot water circulation for bathroom, fittings for equipment and so on.
2. IRG vertical hot water circulating pump is applicable for pressurization and circulating transport of hot water for boiler in such fields as energy, metallurgy, wood processing, chemical engineering, textiles, paper making, hotel, bathroom and guesthouse as well as for the circulating pump in the city heating system. The working medium temperature shall not exceed 120℃.
3. IHG vertical chemical engineering centrifugal pump is applicable for pressurization and transport of the corrosive medium.The working medium temperature shalt not exceed 80C.
4. YG vertical pipeline oil pump is used to transport such oil products as gas, kerosene and diesel oil. The temperature of transported medium is -20℃ ~ +120℃.
