特點和用途
G系列低噪音管道屏蔽電泵采用全封閉、無機械密封的新型結構。定轉子采用不銹鋼套分別屏蔽密封，輸送液體可進入電機內部冷卻，從而解決了普通管道電泵因使用機械密封而導致輸送介質泄漏、污染環境、運行可靠性差、維護困難等問題。轉動部分則采用石磨軸承支承、輸送介質潤滑，是低噪音綠色環保型升級換代產品。由于其低噪音、無泄漏、運行可靠、免維護等優點深得用戶信賴。
G系列屏蔽電泵主要用于暖通空調冷熱水循環，工業、城市建筑給水，消防管道增壓，遠距離輸水等場合。
工作條件
1、本系列流量范圍：1-1080m3/h，楊程范圍：5-105m。
2、電泵系統壓力為1.0MPa（或1.6MPa），即泵吸入口壓力+楊程《1.0MPa（或1.6MPa）。當用戶要求系統壓力高于1.0MPa時，須在訂貨時另行提出。
3、輸送介質為清水或物理和化學性質類似于水的液體，介質溫度《95°C（N型和NY型）或《150°C（GY型），用戶選用GY型須另行配置外循環冷卻水系統；當介質溫度低于20°C時，須在訂貨時另行提出，本公司將采取特殊工藝措施。
