Fish tank fish can not be separated from a variety of small pumps, mainly to provide oxygen and circulate and filter the water, if there is no small pumps, the fish will die of lack of oxygen, so small pumps are very important, but in the choice of small pumps, some friends are more hesitant, in the end is the DC small pumps good or AC small pumps good? Vacuz to give you an introduction to it!

DC small water pump advantages.

First, DC pump safety high human safety voltage is below 36V, 5V-24V DC pump voltage, greatly improving the safety of the pump.

Second, long life, DC pumps use materials are pure copper motor, brushless DC technology and new technology design, more than 30,000 hours of working life, low motor temperature, long-term operation temperature change is not significant.

Third, low noise, DC pumps use a unique vibration and noise reduction design, and flexible suction cup fixed, not only the pump body is stable, but also effectively reduce the noise, sound noise does not exceed 35bd.

Is the small pump DC good or AC good?

1, price DC is cheaper, AC pump is high.

2, AC pumps consume 3000L of water about 100W, DC inverter pumps but only need 30W, so save 70W, running a year to save several hundred degrees of electricity.

3, DC power is safer, generally only need 12/24V water pump can be, are below the safety voltage of 36V, and AC power for 220V, if accidental leakage, it is very unsafe.

4, AC water pump decibel is larger, silent level are greater than 40dB, and DC inverter water pump silent level, can reach 20dB or less, the sound is small, not noisy.

Now small pumps tend to DC brushless motor development, the future is mainly DC, comprehensive consideration, or DC small pumps better, in fact, it depends on personal preference! Choose the right one!
