Features

Small size, high efficiency, maintenance-free, low consumption, strong anti-jamming ability, stable performance
Brushless with no pollution, adopts high-performance ceramics shaft and high-precision carbon fiber sleeve together (stainless steel shaft optional for reducing cost)long life span
Stator and control circuits are completely sealed by epoxy resin completely separated with rotor, waterproof, avoided water-leakage problem which long exists in normal DC motor pump products
Protection functions can be customized such as lock protection, dry-run protection and so on.
Wide range of working voltage; parameters can be adjustable, e.g. 12VDC pump can have lift of 1m and lift of 3m with the same pump body.
For A/S sub-series,soft-start without impact,can be directly powered by solar panel; circuit parts and motor parts completely separated, no electronic components inside pump body; pump body is made of high-temperature-resistant material, so pump can continuously work at fluid with high temperature (as high as 100C); have several protection functions, such as impeller&rotor lock protection, polarity reverse-connected protection, over-load protection, over-current protection, etc.
For A sub-series, it's easy to regulate the power/speed of pump via PWM signal/ 0~5V analog signal/ potentiometer; flow rate & lift can be smoothly adjusted
Reduced the mortality to 0.05% after long-time study by R&D dep.
Lift of pumps can be doubled when they are connected in series
Suitable for submersible installation or land use (should be located below fluid level)
Offer ODM serve for pump and other controller system

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(two wires: positive and negative)
Intelligent program-driving, sensor-less, circuit can be put 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, over-temperature protection
Soft start, no current impact, can be contact directly with solar panel

Diagram of 3phase brushless DC pump connection

S-Series A-Series
Potentiometer Speed adjusting connection:
Contact the red and black wire to both ends of potentiometer(variable resistor),then contact the yellow wire to the middle of potentiometer,Speed canbe changed by turning the potentiometer. Potentiometer speed adjusting is the same with VR speed adjusting(Remove the potentiometer and contact the speed adjusting wire like VR speed adjusting connection bellow).
PWM(50-800HZ/Amlitude 5V) or VR(0-5V) Speed adjusting connection:
Contact the yellow wire to the control system's speed control signal output interface(PWM or VR) and contact the black wire to the ground lead in the control system.hang the red wire on the air.
