NOTE	Information including continuous working time, working temperature and medium is required to be pre-confirmed with professionals; pump cannot work with high temperature or corrosive fluids.   When pump is connected into circulation system, load current will be reduced to 70~85% of Max working current (opening outlet current).   The head means the Max vertical lifting height of water,the flow is 0L/MIN@max head.   The max flow rate means flow rate with no lifting height(according to the curve bellow)

Difference between 2phase & 3phase brushless DC pump

2phase  (T sub-series)

Hall sensor driving, circuit board should be placed inside pump body

3phase (S/A sub-series)

NOTE that 3phase dc is completely different with 3phase AC; 3phase DC means 3 pairs of magnetic polarity & sensor-less, power supply  the same with common DC pump Intelligent program-driving, sensor-less, circuit outside of pump body (main factor that pump can be high-temperature resistant) Speed adjustable by PWM, 0~5V signal or potentiometer(optional) Lock protection,reverse-connected protection, over-vol.&over-current protection, Soft start, no current impact, can be contact directly with solar panel
