This is a mini size submersible water pump. It's equipped with a brushless motor providing smooth and quiet operation than a non-brushless water pump.

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.
3. It can be used in the water or other liquids(without particles and impurities); NOT for viscous and acid-base liquids.
4. DO NOT dry burn the pump, otherwise it would be damaged;
5. Switch on-off the power repeatedly for several times to eliminate the air in the pump impeller and the pipe.
