What should be paid attention to when starting Centrifugal pump For sale? Let's have a simple understanding together!
1. The head produced by Centrifugal pump For sale at a certain speed has a limited value. The operating point flow and shaft power depend on the conditions of the plant system (head difference, pressure difference and line losses) to which the pump is connected. Head varies with flow.
2. Stable work, continuous delivery, no pulsation in flow and pressure.

3. Generally, there is no self-priming ability, and the pump needs to be filled with liquid or the pipeline can be evacuated before starting to work.
4.Centrifugal pump For sale is started when the valve of the discharge pipeline is closed, and the vortex pump and axial flow pump are started when the valve is fully opened to reduce the starting power.
5. Because Centrifugal pump For sale relies on the centrifugal force of the impeller to form vacuum suction to lift the water, when the Centrifugal pump For sale starts, it is necessary to close the gate valve and fill with water. When the water level exceeds the impeller, the air in the Centrifugal pump For sale can be exhausted before starting. After starting, a vacuum is formed around the impeller, which sucks the water upward, and its gate valve can be automatically opened to lift the water. Therefore, the gate valve needs to be closed first.
