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, *2v pump’s head can be 1.5m to 3.5m..
Can be customized

Difference between *-phase and *-phase sensor less BLDC pump
*-Phase    Drived by sensor which should be put inside the pump body
*-Phase    Drived by program, sensor less, whole control circuit can be put outside
Speed adjustable by PWM, analog signals(**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
