Features

l Brushless, permanent magnetic rotor, maintenance-free, long life

l small size, high efficiency, low consumption, low noise

l Ceramic sleeve and ceramic shaft [optional]

l Stator and circuit board sealed by epoxy resin, completely water proof

l Parameter adjustable, 12v pump's head can be 1.5m to 4m..

l Can be customized

Difference between 2-phase and 3-phase sensor less BLDC pump

2-Phase

u Drived by sensor which should be put inside the pump body

3-Phase

u Drived by program, sensor less, whole control circuit can be put outside

u Speed adjustable by PWM, analog signals(0-5v) or potentiometer[optional]

u Locked-rotor and reverse connection protection

u Automatic overload protection and over-temperature protection

u Soft start with low in-rush current, great for PV panel
