Package List: 1 x BS‑40A DC 24V Brushless Booster Pump Note: 1. 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 water‑off protection function. In the absence of water, the pump will automatically stop after 1 minute of rotation. After adding water, re‑insert 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 re‑energized.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.
