Use conditions and precautions of jet pump for well

1. The liquid temperature of the conveying water source is less than +40.

2. The PH value of the well jet pump medium is between 6-8.

3. The solid impurity ratio in water is not more than 0.1% and the particle size is not more than 0.2MM.

4. The power frequency is 50HZ, the single-phase voltage is 220V, the three-phase voltage is 380V, and the voltage fluctuation range is 0.9-1.1 times the rated value.

5. When the temperature is lower than 0 degrees, antifreeze work should be done; when not in use, open the drain screw at the bottom of the pump body for the well jet pump, and drain the water in the pump body to avoid freezing and cracking the pump body.
