GDL型立式多级管道泵是根据本公司ISG型立体离心泵及DL型立式多级离心泵的优点而设计的。在结构上采用了立式、分段形式，泵的吸入口与排出口设计在下方成一字形，并采用了最佳的水力模型。泵的轴向力采用水力平衡方法解决，残余轴向力由一个球轴承承受，因而运转平稳、低噪声、占地面积小、装修方便。外筒体用不锈钢制造，外形美观，特别用于高层建筑多台泵并联使用，以减少单泵机组配代功率，简化电控设备。适用于低高层建筑的住宅、医院、旅馆、百货大楼、办公大楼等的消防、生活供水以及空调机组循环、冷却水输送等。主要性能参数表型号进出口径(mm)流量(m3/h)扬程(m)电机功率(kw)25GDL2-12*3252361.125GDL2-12*4252481.125GDL2-12*5252601.525GDL2-12*6252721.525GDL2-12*7252842.225GDL2-12*8252962.225GDL2-12*92521082.225GDL2-12*10252120325GDL2-12*11252132325GDL4-12*12254144325GDL4-1*3254331.125GDL4-1*4254441.525GDL4-1*5254552.225GDL4-1*6254662.225GDL4-1*725477325GDL4-1*825488325GDL4-1*925499325GDL4-1*10254110425GDL4-1*11254121425GDL4-1*12254132440GDL6-12*3406361.540GDL6-12*4406482.240GDL6-12*5406602.240GDL6-12*640672340GDL6-12*740684340GDL6-12*840696440GDL6-12*9406108440GDL6-12*10406120440GDL6-12*114061325.540GDL6-12*124061445.550GDL12-15*25012302.250GDL12-15*3501245350GDL12-15*4501260450GDL12-15*55012755.550GDL12-15*65012905.550GDL12-15*750121057.550GDL12-15*850121207.550GDL12-15*950121351150GDL12-15*1050121501150GDL18-15*2501830350GDL18-15*3501845450GDL18-15*45018605.550GDL18-15*55018757.550GDL18-15*65018907.550GDL18-15*750181051150GDL18-15*850181201150GDL18-15*950181351550GDL18-15*1050181501565GDL24-12*2652424365GDL24-12*3652436465GDL24-12*46524485.565GDL24-12*56524607.565GDL24-12*66524727.565GDL24-12*76524841165GDL24-12*86524961165GDL24-12*965241081565GDL24-12*1065241201580GDL36-12*2803624480GDL36-12*38036365.580GDL36-12*48036487.580GDL36-12*58036601180GDL36-12*68036721180GDL36-12*78036841580GDL36-12*88036961580GDL36-12*9803610818.580GDL36-12*10803612018.580GDL54-14*28054287.580GDL54-14*38054421180GDL54-14*48054561580GDL54-14*580547018.580GDL54-14*6805489418.580GDL54-14*780549822100GDL72-14*2100722811100GDL72-14*3100724215100GDL72-14*4100725618.5100GDL72-14*5100727022100GDL72-14*6100727430100GDL72-14*7100729830)
