GDL型立式管道多级离心泵Brief Introduction of GDL Vertical Tube-Stage Centrifugal Pumps
特点：Features
本型泵为立式、多级、节段式结构，结构紧凑、占地面积小
Vertical, multi-stage, sectional, compact and small structure;
轴封为机械密封并可选用便拆式，泄漏少，运行稳定可靠，且维修方便快捷
Pump body has tube structure, its inlet and outlet size is the same, and that, they are at a line, can be fixed anywhere like valve, convenient, fast and steady.
为方便安装可选择上出口型，其进出口之间的方向可按用户的要求调整0°、90°、180°、270°
You can choose up-outlet type in order to convenient fixing, the angel between inlet and outlet can be justed0°、90°、180°、270°
如需减震、降低噪音，可采用加装联结板及隔震垫或隔震器的安装方式
If you need low noise and light tremor, isolating-vibrator or isolating-pad and connection board can be fixed.
独特的安装结构大大缩小了泵的占地面积，可节约基建投资40%以上。
The area is small because of special installation structure. 40% investment into building can be saved.
