The difference between DC pumps and AC pumps

AC water pumps:

1.The level of security is not high enough.As is known to all,the safe voltage for human is 36V,but AC pumps uses more than 220V ac power which has high demand on insulation.Once the line is broken,it’s very likely the safety accident will happen because of electric shock.If the pump is in  fish tank,the fish will be in dangerous once electric leakage.

2.Short Lifetime.Because of copper-clad aluminum cable core in ac pump motor,the motor temperature is generally above 120°C.In the condition of realizing same performance parameters,the power consumption of ac pumps is higher than dc water pump.

3.High noise.The ac pumps use backward technology and different material,the noise of ac pump is above 40db universally and the noise would be more and more higher with use time growth. 

DC water pumps:

1.more secure.The voltage is under 12V or 24V which is safe for human body.Even if the wire is broken，we don't have to worry about electric shock.

2.More efficient.All performance parameters are actual,low power consumption and high performance.

3.long lifetime.Using the advanced brushless dc technology and the latest technology design,more than 30,000 operating life.

4.Low noise.Unique damping and noise-reducing design and elastic chuck fixed.The function of DC micro water pump is stable and the maximum noise is less than 35db.

What are the advantages of water dispenser pump?

One.long life

Brushless dc pumps used electronic components for reversing,without using the carbon brush.Meanwhile,using high-performance wear-resistant ceramic shaft and ceramic shaft sleeve, shaft sleeve and magnet are connected into a whole to avoid wear.This is why the life of brushless dc magnetic pumps was enhanced greatly.The life of this pump is 10 years, maintenance-free,small volume with high efficiency and low power consumption.

Two.low noise

The axis of water pump is high performance ceramic shaft,high-precision,good vibration resistance.Due to the precision coordinate of ceramic bushing and ceramic shaft,the noise of pump is below 35DB.If power is smaller,the noise even can be below 30DB,almost silent.

Three. waterproof completely

Part of the motor stator and circuit board is potting by epoxy　and insulated from the rotor completely.This help solve the problem of motor type dc pumps leaking for a long time．Now it can underwater installation and waterproof completely.

Four.A variety of parameters

When the voltage is same,we can make a variety of parameters，for　example：when the voltage is 24v,the pump lift can be 2m,it also can be 7m.In addition，the water pump can run wide voltage, such as　24v pumps also　can run under a condition of less than 24v voltage.

Five.many functions

Water dispenser pump　is the DC pump that can be drived without three-phase hall program．It can realize PWM speed regulation,analog signal input control and potentiometer manual speed control,so that you can regulate the flow and head,can custom music fountain．Ｔｈｅｔhree-phase dc pumps have　function of jammed protection andreverse connection protection.

Six.customizable

The pump can be customized and designed according to customers' requirement.And the pump configured 4 and 6 points pipe thread to meet customers'specific requirements.

Seven.Multifunctional design

Can be used in diving,and also can be put outside(installation position is below the liquid level)

Eight.low price

Brushless dc motor has been standardized,the specialized factory can produce massively,low price and high efficiency.

Nine.temperature resistance

Using high temperature material which withstand 80-100 temperature up to 80-100 degree heat.

Ten.Widely used

　 The water pumps are widely used in computer water-cooling system, Solar fountains, desktop fountain,artware,coffee machines,water dispensers,Oxygenating wine pourer,Soilless cultivation, water mattress, hot water circulation, swimming pool water filtration,auto cooling circulatory system, air conditioner, washing machine, medical equipment, and so on.
