The self-priming pump is a kind of centrifugal pump that boasts self priming function which makes it suitable to lift liquids from containers that are below the pump, and it delivers reliable performance with easy operation. Our self primer only requires liquid filling for the initial use after installation, indicating that this operation is no longer needed for the future use.
1. Since the self-priming centrifugal pump has self priming function, there is no need to use a foot valve, and there should be a certain amount of liquid in the pump casing prior to starting. In this way, the pipe system is simplified, and labor condition is improved.
2. The self-priming pump is featured by compact structure, simple operation, stable running, high efficiency, easy maintenance and long life span. In addition, the pump switch is automatically controlled according to water pressure change in the pipeline.
3. This water pump has a suction lift of 2-4m which changes with the density of pumped liquid, and it is a preferred choice to work instead of clumsy submersible pumps.
