1. Domestic self-priming pump products are pump products for conveying clear water medium. If they are used to pump water in ponds or wells, please install a filter screen at the suction inlet of the inlet pipe of the domestic self-priming pump to prevent sand or other impurities from being sucked into the pump body, resulting in blockage of the domestic self-priming pump or seizure of the impeller. The suction port of the inlet pipe shall be about 0.3m away from the bottom of the pool to prevent particles at the bottom of the pool from being sucked into the pump. If the liquid level is lower than the pump, a bottom valve needs to be installed at the suction port at the bottom of the pool to achieve the function of pumping low liquid level.  

2. For the installation of domestic self-priming pump, it should also be noted that the domestic self-priming pump should be installed in a place with good ventilation. The inlet and outlet pipes should match the standard pipes according to the pipe diameter of domestic self-priming pump, and the joints of the pipes must be sealed with raw material tape.  

3. In order to prevent electric shock, leakage protection measures shall also be installed, and ground wire grounding protection shall be done well.  

4. The power supply of household self-priming pump is 220V civil power supply, the voltage must be stable, and the service range should be between + 5% - 12% of the rated voltage, otherwise the motor is easy to burn out. If the installation point of the domestic self-priming pump is far away from the power supply, it should also be 1. The domestic self-priming pump products are pump products conveying clear water medium. If it is used to pump water in a pond or well, please install a filter screen at the suction port of the inlet pipe of the domestic self-priming pump to prevent sand or other impurities from being sucked into the pump body, resulting in the blockage of the domestic self-priming pump, Or the impeller is stuck. The suction port of the inlet pipe shall be about 0.3m away from the bottom of the pool to prevent particles at the bottom of the pool from being sucked into the pump. If the liquid level is lower than the pump, a bottom valve needs to be installed at the suction port at the bottom of the pool to achieve the function of pumping low liquid level.
