This is a high quality, mini submersible water pump. The spindle is coated with a layer of ZrO2 (zirconium oxide) to withstand higher temperature and have better tolerance to acid and alkaline. It can be used inside or outside of water for pumping. It's built by a brushless motor to provide a smoother and quieter operation than a brush water pump. Also, it will not generate an 'electric spark' like brush type do, so it's safer. (no gasoline*).

Do not let it run dry without water.

The solar panel charger will cause damage the pump during charging period. Warranty will not cover it.
