Feature: 1. The brushless DC motor runs smoothly and has low noise, providing you with a quiet environment. 2. This 12V electric water pump can work continuously for up to 20,000 hours and has a long use time. 3. This pump has IP68 waterproof performance and is suitable for aquariums, aquariums, fountains and hydroponic systems. 4. The submersible pump is made of engineering plastics, which is explosion‑proof and non‑sparking. 5. This water pump can be disassembled without any tools, easy to separate and easy to clean. Specification: Item Type: Brushless Booster Pump Model: BS-40A Material: Engineering Plastic Water Pump Housing Material: PA66+30% Glass Fiber Magnet Material: Plastic Magnet Wire Frame Material: Nylon Material PA66 Rotor Material: Graphite Power Cord Material: PVC Shaft Material: Ceramic Rated Flow: 700m³/h Current: 2.4A Power: 28.8W Waterproof Rating: IP68 Rated Head: 5m Use Environment Temperature: -20℃~80℃ Use Environment Humidity: Below 90%RH Use Medium Temperature: -20℃~100℃ Use Medium: Water, Alcohol, Diesel and Other Liquids with Good Fluidity Use Place: Medical Treatment, Equipment, Electrical Appliances, Etc. Life: ≥30000H Noise: ≤40dB Purpose: Smart Toilet, Solar Water Heater, Dishwasher. Package List: 1 x BS-40A DC12V Ceramic Structure DC Brushless Booster Water 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.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 )
