Pipeline centrifugal pump is pressurized transmission pipeline to solve the pipe pressure is too low and developed a new pump, horizontal centrifugal pump than the current application has great advantages. The superiority of the pipeline pump is mainly reflected in the following points: 1. Pipeline pump for high-rise building pressurized water, garden sprinkler, cooling tower water, long distance water, air conditioning, refrigeration flush, bathroom and other cold; warm water circulation pressure, the use of temperature below 80 ℃. 2. Suitable for heating, boilers and other industries of hot water heating cycle. Operating temperature below 150 ℃. 3. Suitable for conveying corrosive media in the process of foodstuff, pharmacy, brewing, chemical industry, etc., the working temperature is below 80 ℃. 4. Suitable for conveying non-corrosive liquids, methane or coal mine fixed equipment Class I and factories IIA, IIB level, temperature group T1, T2, T3, T4 explosive mixtures exist in other industrial sites. Operating temperature below 80 ℃. 5. The pipeline pump is suitable for transporting industrial corrosive liquids such as chemical, pharmaceutical, petroleum, foodstuff, national defense and the like. There are Class I and IIA and IIB fixed plants in the underground of methane or coal mine, and the group of explosive temperature is T1, T2, T3 and T4 Other industrial sites for mixtures. Operating temperature below 150 ℃.
