Features: This DC pump uses advanced electronic components and high-quality wear-resistant shaft.It is operation, high efficiency, good performance, long service life,Can be a long time continuous work, low noise, safety and environmental protection. It is widely used in industry, scientific research, aerospace industry Usage:The water pump cable ( is positive, do not take the wrong) received a suitable power supply (the battery can be a battery, it can be a power converter), and then a good water pipe, then pump into the water, Can be used normally. (Note: The DC brushless pump is a centrifugal pump, the pump water flow with the increase of the head decreases.No diving without self-priming function, prohibit no water free.)
