High insulation requirements, once the line is damaged, electric shock is very likely to cause safety accidents;
The motor generally uses copper-clad aluminum wire core, the motor temperature is generally above 120°, and the life is not long.
The motor core generally uses pure copper wire core, but the price is comparable to that of DC pumps, but under the same parameters and performance.
The power consumption is higher than that of DC pumps.
The performance parameters in the market are generally unrealistic and false.
After purchase and use, sometimes the power is not enough or too strong. The operation performance of ordinary AC pumps with unstable voltage is unstable.
2. Advantages of DC pumps:
Low voltage is safer. It is below the human safety voltage of 12V/24V DC. Even if the wire is damaged, it does not matter. There is no need to worry about irreversible personal safety accidents caused by electric shock. For areas with unstable voltage, the pump can always maintain stable operation because of the use of power adapters (transformers). There is no need to worry about the stability of the pump. In the case of power outages, the corresponding battery can be used for power supply, and there is no need to worry about the death of fish due to power outages. High efficiency, all parameter performances are actual nominal, strong, and strong enough to use; low power consumption and high performance. Long life, pure copper motor, brushless DC technology, and the latest process design, more than 300 million hours of working life, low motor temperature, and little change in long-term operation temperature. Low noise, unique shock-absorbing and noise-reducing design, and elastic suction cup fixation, not only the pump body is stable, but also the noise can be effectively reduced.
