A multi-stage centrifugal pump is a combination of two or more centrifugal pumps with the same function. In terms of fluid channel structure, it is manifested in that the medium pressure relief port of the first stage is connected to the inlet of the second stage, and the medium pressure relief port of the second stage is connected to the inlet of the third stage. This series connected mechanism forms a multi-stage centrifugal pump. The significance of multi-stage centrifugal pumps lies in increasing the set pressure.
The multi-stage centrifugal pump adopts the highly efficient and energy-saving hydraulic model recommended by the country, which has the advantages of high efficiency and energy conservation, wide performance range, safe and stable operation, low noise, long service life, and convenient installation and maintenance; By changing the material and sealing form of the pump and adding a cooling system, it can transport hot water, oil, corrosive and abrasive containing media, etc.
1. The multi-stage 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, resulting in smooth operation, low vibration, and long service life.
2. The multi-stage centrifugal pump has the same caliber and is located on the same horizontal centerline, without changing the pipeline structure. It can be directly installed in any part of the pipeline, making installation extremely convenient.
3. The motor with a rain cover can be directly placed outdoors for use without the need to build a pump house, greatly saving infrastructure investment.
4. The head of a multi-stage centrifugal pump can meet different requirements by changing the pump stages (number of impellers), so it has a wide range of applications.
5. The shaft seal adopts a hard alloy mechanical seal, which is reliable, leak free, and has minimal mechanical loss.
6. Efficient and energy-saving, with a beautiful appearance.
7. Note: Internal castings with a diameter of 50 or above are formed.
