Is DC pump brush good or brushless good? What's the difference?

In the past, the water pump used brush motor, because of the carbon brush, so easy to produce wear, often need to replace the carbon brush, more trouble; Now the new brushless DC pump, no carbon brush limit, no reversing spark, a wider range of application, easier maintenance, longer service life, favored by the majority of customers, now let's get to know.

1, brushless DC pump relative to the brush pump, the safety performance is higher, brushless DC often uses 24V or 12V voltage power supply, and the AC uses high voltage piezoelectric, higher than the human body 36V, many times prone to safety risks, especially swimming pool swimming, fish tank water change places, so brushless DC is more safe.

2, brushless DC pump energy saving effect is good

The same head effect, AC needs more power, time consumption, carbon brush friction loss is also large; And brushless DC pump low loss, high efficiency, the same power head is brushed several times. For example, a year down, the same power, the use of brushless DC pump, electricity can buy several pumps, so that the comparison, already know who is cost-effective.

3. Brushless DC pump has low noise and long service life

When the brushless DC pump is running, the noise level is below the decibel level of human noise. For example, in the office, the fish tank pump can hardly hear the running sound. And the brush is different, because of the friction of the carbon brush, especially after a long time, the wear gap will be larger, the noise will be larger, affecting the normal work.

4, brushless DC pump heat is small

No matter what motor, heat is unavoidable, brushless water pump low power, withstand high temperature effect is more obvious; And the brush motor consumes more power heating, the heat resistance effect is poor, it is easy to hot.

After reading the above introduction, I believe that everyone almost understands the difference between the two.
