(1) DL型泵供输送清水或物理化学性质类似于水的液体,介质温度不高于80℃。适用于工业和城市给排水。
(2) 性能范围：流量Ｑ4.9～200m3 /h;扬程H21.6～239m。
(3) 型号意义:例80DL×5
80----泵入口直径(mm);
DL----立式多级离心泵;
5----泵的级数。
2、结构
D型泵为卧式安装,吸入口水平,排出口垂直向上。泵的 吸入 段、中段、排出段用拉紧螺栓联结成一体。泵由泵体、叶轮、轴、导叶、导叶套和平衡盘等主要零部件组成。转子的轴向力由平衡盘平衡。轴承采用滚动轴承，用黄油润滑。轴封采用机械密封和填料密封。在填料密封的填料箱中通入有一定压力的水，起水封作用。从驱动端方向看，泵为顺时针方向旋转。
