Features: This DC pump uses stepped forward digital substances and high quality wear-resistant shaft It is comfortable operation, excessive efficiency, nice performance, long service life, Can be many years continual work, low noise, safety and environmental protection. It is broadly used in industry, scientific research, aerospace industry Usage: The water pump cable (red line is positive, don't take the wrong) obtained an appropriate power delivery (the battery can be a battery, it may 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 circulation with the increase of the head decreases diving without self-priming function, limit no water free.)
