The reason why single stage centrifugal pump can't pump water

Although the single-stage centrifugal pump has a certain degree of self-priming capacity, it is still necessary to ensure that the inlet pipe is completely sealed when it is installed.

The reason why the centrifugal pump does not pump water may be that the user does not install it correctly. The correct installation and use of centrifugal pump suction pipe should be installed at the bottom of the pool bottom valve. Before starting, the whole pump body and inlet pipe must be filled with water. The outlet valve must be closed before starting, and then the outlet valve shall be opened slowly after opening the centrifugal pump. Each single-stage centrifugal pump has different self-priming performance according to different models. When choosing the model, you must know each single-stage centrifugal pump.

The reason why the single-stage centrifugal pump can not pump water may also be that the self-priming exceeds the effective self-priming height of the centrifugal pump. The self-priming head of conventional single-stage centrifugal pump is within 3M. If the height exceeds this height, self-priming centrifugal pump or high suction self-priming pump with vacuum auxiliary device must be used.

The reason why the single-stage centrifugal pump can not pump water may also be due to the blockage of debris in pump cavity, impeller, bottom valve, pipeline and other places. If the single-stage centrifugal pump is sealed and has leakage, it will also lead to the failure of pumping.
