GDL型立式多级管道泵[1]是根据ISG单泵头型管道离心泵及DL型立式多级离心泵[2]的优点而设计的结晶，在结gdl型立式多级管道泵构上采用了立式，分段式，泵的吸入与吐出口设计在下方成一字型，并采用水力平衡的方法解决，残余轴向力由一个球轴承承受，因而运转平衡，噪音低，占地面积小，检修方便，以减少单泵机组配带功率，简化电控设备。适用于高低层建筑的住宅、医院、旅馆、百货大楼、办公大楼等的消防，生活供水及锅炉机组循环、冷却水循环输送等。
DL、DLR型立式多级泵是沪龙公司根据高层建筑给水市场的实际需要和国家消防局GB 6245《消防泵性能要求和试验方法》标准而研制开发的多级泵新型产品。DL立式多级泵供输送不含坚硬颗粒及物理化学性质类似于水的介质之用。流量范围为5～360m3/h,扬程范围为22～300m,配套功率范围为1.5～220KW,口径范围为φ40～φ200m。同一台泵的出口可设1～5个出口，低转速n=1450r/min。
