DGC型泵是雙層殼體磁力驅動多級離心泵。該產品旨在解決小流量，高揚程的流體輸送問題。該產品結構設計、水力設計及磁路設計先進新穎，技術達到國內領先水平。首家成功地將磁力驅動技術應用于多級離泵，解決了大功率，大間隙磁路設計問題，居國內領先地位。同時解決了高工作壓力下多級泵的軸向力平衡及靜密封問題。磁力驅動聯軸器及軸承失效監控裝置的配合，更保障了泵長期安全可靠運行。
適宜輸送不含固體顆粒的易燃、易爆、劇毒的介質和其它要求無泄漏及不允許密封污染的介質。廣泛地應用于油田增壓注水，高中壓遠距離輸水、輸油，電廠疏水泵，煉化和煤化工行業液烴泵、順丁像膠，加氫精制及鉑重速裝置等。
DGC is a kind of magnetic-driving, double-casing, multi-stage centrifugal pump, aiming to solve the problem of conveying liquid of little capacity, high-lift. The structure design, hydro -mechanical design and magnetic design are domestically advanced. HIGHLAND is the leading company that has successfully applied magnetic driving technology into multi-stage pump in
It is suitable to convey inflammable, explosive, severely poisonous mediums without solid particles, and other mediums requiring no seal pollution. It is widely applied into oil field pressurizing water injection, long-distance conveying water or oil under high and middle pressure, drain pump plant, petrochemical and coal chemical industry liquid hydrocarbon pumps, butadiene rubber, hydrofining and platinum heavy speed devices, etc.
結構特點Design features
（1）臥式徑向剖分，外殼為筒形結構，內殼為節段式結構
（2）全密封、無泄漏，無污染
（3）根據介質溫度選用底腳支承(基本型)和中心支承(高溫型)
（4）大功率磁性驅動
（5）入口可水平、垂直或側向任意角度布置，水平布置更利于采取的措施提高泵的抗汽蝕性能
（6）出口可垂直或側向任意角度布置
（7）可選用與電機直聯或帶膜片連接器兩種結構
（8）內循環的冷卻和潤滑方式，更適宜輸送各種流體介質，包括易汽化介質
（1）Radial horizontal subdivision, cylindrical outer shell, sectional inner shell
（2）Fully sealed, non-leaking, non-polluting
（3）The foot support (basic type) and the center support (high-temperature type) can be adopted according to the medium temperature.
（4）High-power magnetic driving
（5）The inlet can be horizontally, vertically or laterally arranged or in any other angle; the horizontal layout is more conductive to the measures taken to improve the anti-cavitation performance of the pump.
（6）The outlet can be in vertical arrangement or lateral in any angle.
（7）Direct motor linking or by connector with prince film
（8）Internal recycling way of cooling and lubricating; it is more suitable for conveying a variety of fluid mediums, including the easily-vaporized mediums.
