Why is the plastic self-priming centrifugal pump always broken

1、 The plastic self-priming centrifugal pump needs to be disassembled and cleaned regularly.
Due to the internal rotation direction of plastic self-priming centrifugal pump and the nature of impurities, a small part will remain in the pump, and impurities are easy to nest between turbine chamber and rotor stator. These dirty things will reduce the water flow of the pump, increase the working temperature and increase the noise.
Therefore, it is recommended to clean the plastic self-priming centrifugal pump once a month, open the protective cover, remove the turbine, rotor and shaft, thoroughly clean the interior, and clean the surface or dead corner with waste toothbrush.
2、 The plastic self-priming centrifugal pump shall not be installed too close to the sand.
Some people like to install the plastic self-priming centrifugal pump close to the bottom. They think that the dirt will be pumped thoroughly. In fact, it is meaningless. As long as the water pump is circulating, the dirt will be pumped into the filter with the water flow.
In addition, do not let the outlet of the plastic self-priming centrifugal pump face too close obstacles, and do not deliberately block the outlet or half of it. These practices will shorten the service life of the plastic self-priming centrifugal pump.
