四．Additional function instructions |
1 | K-jam protection | When the impurity enters the rotor chamber, the rotor stops running, and the pump stops running as well. |
2 | Water Shortage/Dry run protection | When the pump is short of water or idling, the pump will cyclically stop (8 seconds) and run (2 seconds), and the protection strategy can be customized |
3 | Overloading protection | When the voltage is unstable or exceeds the rated power, the pump will stop working |
4 | Power reverse connection | Wrong connection of the power supply(positive and negative), the water pump will stop running, and then re-connected, can work normally. |
| Pump with built-in driver | 
| For external use |
| Pump with external driver |  | Suitable for high temperature or corrosive solution submersible and external use |
