Features: Small size, high efficiency, low power consumption, strong anti-interference ability, and stable operation. No carbon brush, no pollutions, electronic commutation, long life. Optional speed regulation function (PWM speed regulation, 0~5V analog signal speed regulation, potentiometer speed regulation). If the pump for head needs to be increased, the pumps can be connected in series, and the for head can be doubled. Amphibious (installed below the liquid level for external use). Specifications: Material: Engineering Plastic Drive Mode: Brushless, Magnetic Isolation Working Method: Can Be Used Continuously Maximum Working Temperature: 70℃ Power Consumption: 19w Max Load Power: 19w Maximum Flow: 800l/h Maximum Static Lift: 6m Noise: <35db Waterproof Grade: Ip68 (submersible Installation) Life: More Than 10000 Hours Rated Voltage: 12v Maximum Speed: 9500rpm Package Includes: 1x Water Pump note: 1. Please allow 1-2cm errors due to manual measurement, make sure that you do not mind before you order. Due to the difference between different monitors, the picture may not reflect the actual color of the item. 2. This water pump is a submersible centrifugal-water pump, the water pump must be immersed in water, or the level of the external water source must be lower than the water inlet nozzle of the water pump when the pipeline is connected, so that the air is discharged after the water enters the water chamber of the water pump, and the water pump can work normally. 3. When choosing a water pump, be sure to give the use environment: such as continuous working for time, water temperature, medium, etc., the pump power exceeding 24W is not suitable for long-term continuous work at a water temperature above 65 degrees. 4. The lift of the pump is the maximum water delivery height, that is, the flow reaching the maximum lift point is 0. 5. The flow rate of the water pump is the horizontal flow rate, that is, the flow rate of horizontal pumping. 6. This pump cannot work without water for a long for time.
