Specifications: Model: DC50B-1280S Material: PA66+GF30% Power consumption: 45.6W Rated voltage: 12V Rated current: 3.8A Max flow rate: 22.2L/MIN Max static head: 8m (26ft) Diameter of inlet: 22.5mm Diameter of outlet: 22.5mm Noise: <40dB Waterproof level: IP68 Lifespan: More than 30,000hrs Power supply: DC electric source (bared wire) Driving method: Brushless, Magnetic, 3-phase Max working temperature: 100¡ãC/212F Item dimension: 100.5*84.5*64mm SKU: X1HG10020 Note: 1. Working at rated voltage (DC12V/3.8A ). The positive pole is red wire, the negative pole is black wire/blue wire. 2. This pump is centrifugal pump, it can"t vent the air automatically, so it must be operated by submersible installation. (If outside water installation, you should make sure it is installed below the liquid surface) 3. When blocking, long-running is not allowed. 4. Preventing any hard particles entering the pumps. How to Choose pump: 1. Make sure the working voltage, current, head and flow. The Max head means the static head. The pump can lift to the max height when there is no flow. If you want special flow at special height, you must choose more higher head than the height you want to pump; 2. Make sure the dimension (threaded interface or not, the direction and diameter of outlet and inlet); 3. Working environment (temperature and medium); 4. Other functional requirements, such as time control, motion control, pressure control, flow control, and speed adjustment. Package includes: 1 * Water pump
