gdl型多级管道离心泵是我公司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产品。
本型泵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,同时由于采用了优秀的水力模型,所以还具有高效节能,运行平稳等优点,且轴封采用耐磨机械密封,无泄漏使用寿命长。
为了能更好地满足用户的要求,本单位还开发了出水口位于上部的gdls型,其进出口可以不同的相对位置(0°、90°、180°)安装,使用极为方便。
为了使用户能更加安全、可靠的使用该型泵,本单位特别研制了便拆式结构型,它除拥育gdl、gdls的一切优点外,更为您更换机械密封等易损件提供了更加充便,快捷、省力的途径,使本型泵更无忧运行与维护。
the product summary 
  gdl s mould many stages pipeline centrifugal pump is the use that my corporation at home and abroad on the foundation of outstanding pump mould combines user is asked and fire fighting about the standard , and the new generation product made according to jb/tq6435-92 s standard design .
this mould pump uses the more stainless steel shell aspect structure of vertical section segmentation , and it is identical to make that the imports and exports of pump are located on the same level line and the bore , can install among yu guanlu like the valve , concentrated many stages pump  high-handed of its at the same time , the vertical pump  covers an area of the area small and the pipeline installation of the pump convenient  the merit , at the same time owing to has used the outstanding waterpower model , so still possessing high efficiency save energy , moves smooth and steady waits the merit , just axle seals uses wear-resisting machinery seals up , haves leaks service life is long.
in order better to satisfy the requirement of user , that this unit has still developed appears above water mouthful gdls s mould that is located top , and the relative position ( 0 ° , 90 ° and 180 ° ) that his imports and exports can be different installs , and it is very convenient to use.
what for the use family can be safer and reliable  uses this mould pump , and this unit especially has developed just the dismantling type structure mould , and it gives birth to gdl excepts holding in arms and all merits of gdls , more more your changes mechanically close etc yi sunjian has provided filling more further just , and prompt and the person who saves effort  the way makes a mould pump more not have worrying about operating and maintenance.

应用范围
