The loss caused by this shall be borne by yourself VoltageScope(DC): 12V/24V Current(A): 1.4A/1.1A Power(W): 16.8/26.4 Max WaterHead(M): 5/7 Max FlowRate (L/H): 700/800 Starting Voltage: 6 Waterproofing grade: IP68 Ambient temperature: -20 degrees to 100 degrees Ambient humidity: 90% RH or less Use medium temperature: -20 degrees to 100 degrees Use medium: water, alcohol, diesel, etc. Lifetime: 30000H Insulation withstand voltage test: 1500V 60 seconds Unpitched sound: 35dB Pump housing material: PA66+30% glass fiber Magnet material: ferrite permanent magnet Enamelled copper wire: 2UEW temperature resistance 150 degrees Rotor material: POM Wire frame material: nylon material PA66 Power cord material: PVC Shaft material: 316 stainless steel Precautions for use: 1. The water pump is a DC water pump, and the voltage must be DC power supply (such as battery, DC power supply marked with DC, transformer), and the voltage can be used within the specified voltage range. 2. It is strictly forbidden to dry for a long time without water 3. It is strictly forbidden to use in acidic and alkaline solutions. 4. It is strictly forbidden to use in the liquid of impurities and magnetically permeable particles larger than 0.35MM. If the water quality is too dirty, it is necessary to clean the impurities in the pump pump chamber in time.
