D、DG型卧式多级泵产品特点：
1、水力模型先进，效率高，性能范围广。
2、泵运行平稳，噪音低。
3、轴封采用软填料密封或机械密封，密封安全可靠、结构简单，维修方便快捷。
4、轴为全封结构，确保了不与介质接触，不锈蚀，使用寿命长。
D、DG型卧式多级泵结构特点：
D、DG型泵进、出水口均为垂直向上，通过拉紧螺栓将泵的进水段、中段、出水段、轴承体等泵壳体部分联结成一体。根据泵的扬程选择泵的级数。该系列泵转子部分主要由轴及安装在轴上的叶轮、轴套、平衡盘等零件组成，其中叶轮的数量根据泵的级数而定。轴上零件用平键和轴螺母紧固使之与轴联为一体。整个转子由两端滚动轴承或滑动轴承支承。轴承按型号不同而定，均不承受轴向力，其轴向力由平衡盘平衡。泵在运行中允许转子在泵壳中轴向游动，不能采用向心球轴承。滚动轴承用油脂润滑，滑动轴承用稀油润滑，并用油环进行白润滑，循环水冷却。泵的进水段、中段、出水段之间的密封面均采用二硫化钼润滑脂密封，转子部分与固定部分之间装有密封环、导叶套等进行密封， 当密封环和导叶套的磨损程度已影响泵的工作性能时应予更换。的密封形式有机械密封和填料密封两种。泵采用填料密封时，填料环的位置安放要正确，填料的松紧程度必须适当，以液体能一滴一滴渗出为宜。泵各种密封元件装在密封箱内，箱内要通入一定压力的水，起水封、水冷或水润滑作用。在轴封处装有可更换的轴套，保护泵轴。
次高压泵一般采用滑动轴承、稀油润滑结构，DG85-6 7、DG155-67型泵可采用滑动轴承、 稀油润滑，也可采用滚动轴承、干油润滑结构，其余型号均采用滚动轴承、干油润滑结构。中、低压泵的主要零件材料一般采用优质铸铁，次高压泵主要零件采用铸钢或不锈钢。该系列泵通过弹性联轴器由原动机直接驱动，从原动机方向看，泵为顺时针方向旋转。
