Using encapsulate motor (water filled motor)
No risk of leakage ,effectively higher ,life longer than oil motor.

Using thrust bearing, lower parts loss 
The thrust bearing effectively higher ,life longer. 

Using the brushless DC motor , long service life, low noise and good safety
BLDC motor Efficiency higher 10% than AC motor, higher RPM make pump size smaller than AC motor , much easier installation. The service life of Brushless DC motor can reach 10000 hours, while the brush and slider of Brushless DC motor are worn, and the maximum service life is 2000-3000h. Without MPPT controller, the efficiency of Brushless DC motor is very low, at the same time, there is no protection, the noise is very large, and the safety performance is obviously lower than that of Brushless DC motor.

Obtained a number of certification, reliable quality
The company obtained ISO9001 & ISO14001 certification, and the products obtained TUV SUD & UL certification.

Voltage range ,we offer much Wider scope than any other factory ,make pump system much more smart .
