A multistage pump is a pump that has two or more impellers. They can absorb water and press water in multiple stages , so that the water can be raised to a high position. High head can be reached by adding or reducing the numbers of impeller.
Features
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, so the operation is stable, the vibration is small, and the service life is long.
2. The multi-stage centrifugal pump has the same caliber and is on the same horizontal centerline. It can be directly installed in any part of the pipeline without changing the pipeline structure. It is very convenient to install.
3, the motor plus rain cover can be directly placed outdoors, without the need to build a pump room, greatly saving infrastructure investment.
4. The multi-stage centrifugal pump head can meet different requirements by changing the number of pump stages (the number of impellers), so it has a wide application range.
5. The shaft seal is made of hard alloy mechanical seal, the seal is reliable, no leakage, and the mechanical loss is small.
6, high efficiency and energy saving, beautiful appearance.
7. Injection molding of internal parts with a diameter of 50 or more.
