For this pump， we believe that two points must be emphasized:

       1. It is a DC brushless motor， polarity is not reversed， the red line then positive， black to negative， if reversed， it will damage the brushless motor.

       2. The pump itself is not self-priming and must be installed in a horizontal direction at work， or carry out irrigation discharge air.
Brushless DC Pump new elements， exquisite workmanship.
