产品概述
DG型泵适用于输送不含固体颗粒的清水或物理、化学物质类似于清水的液体。被输送介质的温度为0℃～80℃。
结构特点
DG型泵系单级、多吸、节段式离心清水泵。除DG16-60型泵的吸入口方向垂直向上外，其余泵的吸入口方向为水平。所有D型泵的吐出口方向垂直向上。轴向力由平衡盘来平衡。轴封均采用软填料密封。除DG85-67，DG155-67型泵采用滑动轴承，稀油润滑外，其余采用滚动轴承，油脂润滑。
泵的转向从原动机端看为顺时针方向旋转。
泵的过流部件材质为铸铁，轴的材质为45号钢。如用户有特殊要求，订货时可向厂家提出。
泵与电机、底座配套供应，可配公用底座或本身底座，厂方还提供附件（包括吐出锥管、闸阀、底阀、止回阀）和备件（包括叶轮、密封环、导叶套、平衡盘、轴套）。
