特點: Features 全封閉式、無軸封（只有靜密封而無動密封）的獨特結構保證機組決不泄漏； 封閉的自循環結構可輸送任何介質而保證不對環境造成污染； 采用全新的低轉速屏蔽電機及介質循環系統保證機組低振動、低噪音、低溫升； 泵體采用管道式結構，其進出口徑相同且位于用一直線上，能像閥門一樣安裝在管道的任何位置，方便、快捷、穩固； 無軸封、無滾動軸承、無需維護、運行可靠； 使用隔振墊、隔振器及金屬波紋管等隔振裝置后其震動更小、噪音更低； 獨特的安裝結構大大縮小了泵的占地面積，可節約基建投資40%以上。 Particular and fully cased structure without shaft sealing (there is only a static sealing but no dynamic sealing ensures a high quality sealing of the machine) Closed self-circulation structure is suitable for transporting any sort of liquid without any pollution to environment; Entirely new and low speed cande cande motor as well as liquid circulation system ensures a low vibration, noise and temperature-rise of the machine. Pipe structure, similar inlet and outlet diameters are on the same line which can be fixed at any place on the pipe just like valves, convenient, quick and stable. Pump has no shaft seal and rolling bearing, so it needs no maintenance and operation is dependable. Lower vibration and noise due to vibration devoices such as vibration cushion, this saves capital construction invest by 40% and over. 用途 Applications 建筑物空調系統冷水循環； 建筑物空調系統冷凍水循環； 建筑物空調系統熱水循環； 廠礦封閉回路中冷熱水循環； 建筑物生活及消防用水； 變換材質可廣泛使用于石油、化工、制藥、食品、制冷及原子能等行業； Cold water circulation, cooling water circulation or hot water circulation in air-conditionings system of buildings; Cold or hot water circulation in close way back system of factory and mine; Water used for life of fire fighting of buildings; It can be widely used in industries such as oil, food, refrigeration and nucleates.
