GDL型立式多级管道泵是我单位在国内外优秀泵型之基础上结合用户的使用要求及消防有关标准，并根据JB/TQ6435-92标准设计制造的新一代泵型产品，具有高效节能、占地面积小、安装方面、运行性能稳定等特点。采用立式节段式外加不锈钢壳体结构，使得泵的进出口位于同一水平线上且口径相同，能象阀门一样安装于管路之中，它同时集中了多级泵之高压，立式泵之占地面积小及管道泵之安装方便的优点。GDL型泵轴封采用耐磨机械密封，无泄漏使用寿命长。外套用1Cr18Ni9Ti优质不锈钢，轴承用耐磨机械密封，无泄漏，使用寿命厂。以水力平衡解决轴向力，因而多级管道离心泵运转平稳，低噪音，安装条件优于DL型多级立式离心泵，可以简便安装于任一段水平管路中间。
GDL型立式多级管道泵使用温度≤100℃ ，压力≤1.6Mpa(16kg/cm2)，流量：5-300m3/h,扬程：5-250m转速2900r/min,GDL型立式多级离心泵完全能满足高层建筑、深井矿等的给排水及消防设施需要，是广大行业冷热水或一般介质、理化性质类似水等液体输送的最佳泵行。
立式多级管道泵产品用途
GDL型立式多级管道泵适用于高压运行系统中输送清水或物理化学性质的液体，如高层建筑给水、锅炉给水、消防系统等输送或管道增压之用。GDLF型多级离心泵采用整体不锈钢(ZG1Cr18Ni9Ti)材质制造，适用于化工、食品、酿造、制药、纺织等行业。根据用户的要求可定制不锈钢304或316L材质。
