This is a compact size submersible pump(none self-prime). It's built by a brushless motor providing smooth and quiet operation than a non-brushless pump.

Features:
Brushless, permanent rotor, maintenance-free.
Stator and circuit board by epoxy resin.
Enclosed with static sealing, not dynamic, which can leaking problems.
Small size, high efficiency, low consumption, low noise (less than 35db).
Wide resistance from 0°C to 60°C.
Used in Aquarium, car cooling, , conditioner, other cooling and circulation systems.

Note:
1. It can be used in the or other liquids(without particles and impurities); NOT for acid and alkali solution.
2. DO NOT dry burn the pump, otherwise it would be damaged;
3. PLEASE let the pump vibrate several times in the to exhaust , then it can work normally.
