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 1.5m to 3.5m..
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
