The water pump is a DC water pump and the voltage must be DC power supply (such as batteries DC power supplies marked with DC transformers) and the voltage is within the specified voltage range before it can be used.2. The water pump has its own wateroff protection function. In the absence of water the pump will automatically stop after 1 minute of rotation. After adding water reinsert the power supply to operate normally.3.The water pump has a jam protection device. When impurities enter the pump body during use after the rotor is jammed the water pump will automatically stop running. After the power is removed to clean the impurities the power can be reenergized.3. It is strictly forbidden to use it in strong acid and strong alkaline solutions.4. It is strictly forbidden to use it in liquids with impurities and magnetic particles larger than 0.25MM. If the water is too dirty clean up the impurities in the pump room in time.5. The water pump itself is not equipped with a power supply (transformer). If a power supply is required it must be equipped with a power supply that is marked water pump + power supply. If there is no power supply all are pumps! The water pump is a DC water pump voltage DG24V water pump with DC24V power supply voltage DC12V water pump with DC12V power supply can be used. (Can not use AC voltage directly only the pump with power supply can be used directly by plugging in )
