  • 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


Electrical parameters (only for reference,parameters can be customized for specific requirements)

Model No.VoltageMax load currentMax static liftMax flow ratePower consumption
  • 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

(T sub-series)
  • Hall sensor driving, circuit board should be placed inside pump body

(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
