GDL vertical multistage centrifugal pump has the remarkable features of small footprint, light weight, energy saving, high efficiency, low noise, smooth operation, long service life and beautiful appearance, etc. It is an ideal replacement product. It is suitable for fire-fighting, living water supply and air-conditioning unit circulation, cooling water transportation in high and low-rise buildings, hospitals, hotels, department stores, office buildings, and so on. Next, let's find out how GDL vertical multistage pump works? As well as vertical multistage pipeline pump main use and main advantages.
Working Principle:
GDL vertical multistage centrifugal pump is a novel pump developed for pipeline pressurized delivery and solving the problem of low pipeline pressure, which has great superiority over the application of horizontal centrifugal pump. Due to the use of mechanical seals, the motor spindle directly mounted impeller, according to the head and flow rate needs to be used in tandem. When the motor drives the impeller on the shaft to rotate at high speed, the liquid inside the impeller will be thrown to the surrounding of the impeller from the center of the impeller along the flow channel between the blades under the action of centrifugal force. As the liquid is subjected to the action of the blades, the pressure and speed increase at the same time, through the flow channel of the guide shell and be led to the next level of the impeller, so that, one by one, flow through all the impeller and the guide shell, and further increase the pressure energy of the liquid. After stacking each impeller step by step, a certain head is obtained.
Main Applications:
1. GDL multistage pipeline pump is suitable for high-rise building water supply, garden sprinkler irrigation, long-distance water transmission, air-conditioning, refrigeration flushing, bathrooms and other cold and warm water circulation pressurization.
2. It can be also used in high temperature hot water pressurization circulation in heating, boiler and other industries. The use of temperature 150 ℃ or less.
3. This machine is available for conveying corrosive medium in the process of food, pharmacy, wine making, chemical industry, etc. The use temperature is below 80℃.
4. It is suitable for conveying non-corrosive liquids, methane or coal mine underground fixed equipment class I and factory IIA, II B class and other industrial places.
5. Vertical pipeline pumps are suitable for conveying corrosive liquids in chemical industry, pharmaceutical industry, petroleum industry, foodstuff industry, national defense industry and other industrial places with methane or coal mine underground fixed equipments class I.
Key Advantages:
1. GDL type vertical multi-stage centrifugal pump is of vertical structure, featuring small footprint, pump center of gravity coincides with the center of pump foot, thus running smoothly, low vibration and long life.
2. The caliber of the machine is the same and on the same horizontal centerline, no need to change the pipeline structure, can be directly installed in any part of the pipeline, the installation is extremely convenient.
3. the motor plus rain cover can be directly placed in outdoor use, in other words, no need to build a pump house, greatly saving infrastructure investment.
4. The head of GDL type vertical multistage pump can be changed to meet different requirements by changing the number of pump stages (number of impellers), so it has a wide range of application.
5. The shaft seal adopts hard alloy mechanical seal, which is reliable, no leakage and small mechanical loss.
6. Unique design of hydraulic parts, good overflow performance, minimize flow noise.
7. Adopting high quality mechanical seal, wear-resistant, no leakage, long service life, low failure rate, with less operation and maintenance costs.
