特点和用途
G系列低噪音管道屏蔽电泵采用全封闭、无机械密封的新型结构。定转子采用不锈钢套分别屏蔽密封，输送液体可进入电机内部冷却，从而解决了普通管道电泵因使用机械密封而导致输送介质泄漏、污染环境、运行可靠性差、维护困难等问题。转动部分则采用石磨轴承支承、输送介质润滑，是低噪音绿色环保型升级换代产品。由于其低噪音、无泄漏、运行可靠、免维护等优点深得用户信赖。 G系列屏蔽电泵主要用于暖通空调冷热水循环，工业、城市建筑给水，消防管道增压，远距离输水等场合。
工作条件
1、本系列流量范围：1-1080m³/h，杨程范围：5-105m。
2、电泵系统压力为1.0MPa（或1.6MPa），即泵吸入口压力+杨程《1.0MPa（或1.6MPa）。当用户要求系统压力高于1.0MPa时，须在订货时另行提出。
3、输送介质为清水或物理和化学性质类似于水的液体，介质温度《95°C（N型和NY型）或《150°C（GY型），用户选用GY型须另行配置外循环冷却水系统；当介质温度低于20°C时，须在订货时另行提出，本公司将采取特殊工艺措施。
