Small size, high efficiency, low noise.
Suitable for aquarium, fountain, car cooling, computer water cooling system and circulation systems.

Note:
1. Please check the voltage and power of the pump power before power on. 
2. Please cut off the power before you install/put in/take away the pump from the water; otherwise, the pump can't outlet water due to the air in it.
