50-05b brushless DC motor drive pump for radiator, coolant(Aluminium Alloy casing )
Feature:
1. The pump is designed for three phase to enhence its power that is over 40 watts.
2. Life: Expected life span is about 20000 hours.
3. Low noise: ≤ 40dB, far from 10cm distance.
4. Duty work: The pump can sustain heavy duty work for a day. Continuous operation.
5. Working conditions: Applying to indoor and outdoor under temperature 40degC.
6. Working temperature: -40degC -- 130 degC.
7. It is waterproofand can be submersible. But, do not keep the pump work in water for long time.
8. This pump is our newest design, it is made of ALUMINM material that has very good heat dissipation, it can work in hot water a whole day, and its body temeprature is as the room temperature after long working time.
It specially use for electric vehicle system. It has good performance: Works quietly; Energy saving; High efficiency; Environment protection; We can offer over voltage protection, overheat protection, run-dry protection, over current protection, signal feedback, speed control, ect. All the functions are custormized according to your request.

Power supply:
It can be powered directly by Solar panel; DC electric source; Battery.
Caution: Do not operate for long time when there is no water in the pump.
