Model meaning


Product introduction

GDL vertical centrifugal pump is designed and manufactured with reference to foreign advanced products. The impeller, guide vane and guide casing are stamped, stretched and welded using stainless steel plate, and the carbide seal and guide bearing are used. With the advantages of small size, light weight, high efficiency, energy saving, low vibration and noise, stable operation, long service life, vertical installation, small footprint, light weight and beautiful appearance, it is an ideal replacement product.


Features

1. The GDL type vertical centrifugal pump is a vertical structure with a small footprint. The center of gravity of the pump coincides with the center of the pump foot, so it runs smoothly, has small vibration, and has a long life.

2. GDL vertical centrifugal pumps have the same caliber and are on the same horizontal centerline. They can be directly installed in any part of the pipeline without changing the pipeline structure, which is extremely convenient to install.

3. The motor plus rain cover can be directly used outdoors without building a pump room, which greatly saves infrastructure investment.

4. GDL vertical centrifugal pump lift can meet different requirements by changing the number of pump stages (number of impellers), so it has a wide range of applications.

5. The shaft seal adopts hard alloy mechanical seal, which has reliable sealing, no leakage, and small mechanical loss.

6, high efficiency and energy saving, beautiful appearance.

7 、 Injection molding of inner parts with diameters above 50.


Product Usage

GDL type vertical centrifugal pump is particularly suitable for boiler water supply, and can also be widely used in pressure vessel water supply, hot water circulation, high-rise building water supply, farmland irrigation, fire boosting, hydraulic flushing, food, brewing, medicine, chemical, aquaculture, Various industries such as environmental protection, chemical process and machine tool support are used as power equipment for water supply and drainage.


Conditions of Use

1. For transporting clear water or liquids with similar physical and chemical properties to clear water;

2. There should be no solid particles, no fibers, no strong corrosiveness, and no explosion danger in the conveyed liquid;

3. The maximum liquid temperature does not exceed 120 ° C;

4.The maximum working pressure does not exceed 2.5MPa;

5. The power supply is 3-phase 380V, 50HZ. The voltage fluctuation is within ± 5%;

6. The ambient temperature should be lower than 40 ℃, and the relative humidity should be lower than 95%.
