The scope of use of the submersible water pump
Every evaporative air cooler requires a submersible pump to pump water up to wet the evaporative cooling pad. The power of the submersible pump varies according to the air volume of the evaporative air cooler. The power range of the evaporative air cooler Submersible Water Pump is often between 8-75 watts.
Small portable evaporative coolers generally use submersible pumps with a power of 8W-40W. Large stationary ducted evaporative coolers generally use 45W or 75W submersible pumps. Evaporative air cooler submersible water pumps are also commonly used in misting fans and cooling pad-exhaust fan systems.

Comparison of the new submersible pump with the old one
The new submersible pump has a larger housing with two screw posts. The new model has more suction power and less noise.
The motor coils of the new submersible pumps are thicker. The size of the motor coil directly affects the suction power of the pump. Read more about the importances of copper coil water pump.
The new submersible pump has a built-in anti-dry burning device. Old pumps are prone to burnout in the dry burning state.
The shaft core of the new submersible pump is made of ceramic, which is wear-resistant, acid-resistant and has a long service life. The shaft core of the older submersible pump was made of conventional stainless steel. In seawater or corrosive liquids, 201 stainless steel or 430 stainless steel is easy to rust and cause damage.
The new submersible pump has a power cord length of 1.5 meters. The power cord of the older submersible pump was less than 1 meter long.
The effect of water pump damage on the air cooler
During the long-term use of the air cooler, the dust and sediment from the outside enter the interior of the air cooler. After impurities precipitate, it is easy to block the water pump. The water pump is prone to burning after lack of water. Burning the water pump can easily lead to a fire in the air cooler. Therefore, the dry burn-out function of the new submersible pump is very important.
The head of the old pump was insufficient to fully wet the evaporative cooling pads. The cooling effect of the air cooler will be weakened if the air cooler pad is not sufficiently wetted.
Accessories for evaporative air cooler Submersible Water Pumps
Thermal protection
In the state of water shortage, the temperature of the submersible pump reaches 80°C will trigger the thermal protector to power off.
Sealed process
Each submersible pump will be sealed with gum to prevent water leakage and electricity leakage.
Copper wire coil
Compared to aluminum wire coils, the service life of thickened copper wire coils is doubled.
Ceramic shaft
Ceramic shaft has the characteristics of self-lubrication, wear resistance, low noise, easy assembly, long life, small loss, impact resistance and good toughness. Especially suitable for corrosive, acidic and alkaline and other harsh environments.
