D型卧式多级离心泵是单吸多级分段式离心泵,供输送温度不高于8O℃的清水及物理化学性质类似于水的液体。适用于矿山排水和城市、工厂给水之用。泵的扬程随着级数的增加而按正比例增加,而相对应的流量则不改变。泵吸入口位于进水段上成水平方向,出水口在出水段上垂直向上。从电机端看泵,泵应顺时针方向旋转。

本型泵之装配良好与否对性能之影响特别显著,尤其各个叶轮的出口中心,必须对准导叶进口中心,其中稍有偏差,即将使整个性能受到影响,降低泵效率。其次,转子部分与定子部份的各个密封间隙均有严格规定,间隙太大则引起泄漏量增加,使效率降低;若间隙太小,则会引起零件的磨损或振动,以致降低泵的使用寿命。为此,本泵必须有良好的同心度,方能使泵转动轻快。
