Features
Brushless, permanent magnetic rotor, maintenance-free, long life
small size, high efficiency, low consumption, low noise
Ceramic sleeve and ceramic shaft [optional]
Stator and circuit board sealed by epoxy resin, completely water proof
Parameter adjustable, 12v pump's head can be 2m to 5m..
Can be customized

Difference between 2-phase and 3-phase sensor less BLDC pump
2-Phase Drived by sensor which should be put inside the pump body
3-Phase Drived by program, sensor less, whole control circuit can be put outside
Speed adjustable by PWM, analog signals(0-5v) or potentiometer[optional]
Locked-rotor and reverse connection protection
Automatic overload protection and over-temperature protection
Soft start with low in-rush current, great for PV panel
