Description of additional functions
Jamming protection Pump stops working when jammed Water shortage/idling protection The pump will stop (8 seconds) and run (2 seconds) cyclically when the pump is out of water or idling, the protection strategy can be customized. Overload protection When the voltage is unstable or for other reasons exceeds the rated power of the pump, the pump will stop running. Reverse power connection When the positive and negative poles of the power supply are reversed, the pump stops running, and after reconnecting, it works normally. Pump driver built-in 
Suitable for external land use Pump driver external 
Suitable for high temperature or corrosive solution submersible installation Flow rate and head curve

Parameter Test Installation Diagram
Note: This product does not have the function of self-priming, so when installing, you need to ensure that there is enough water in the gland cavity, that is, when installing, you need to ensure that the center of the pump is lower than the liquid level in the tank to ensure that the pump can operate normally!
