8 | Minimum input power supply： | 12V-5A | 24V-3A | 24V-4A | 36V-3A | |
1 | K-jam protection | When the impurity enters the rotor chamber, the rotor stops running, and the pump stops running as well. | ||||
2 | Dry run protection | The pump will stop working when no enough water inside pump. | ||||
3 | Overloading protection | When the voltage is unstable or exceeds the rated power, the pump will stop working. | ||||
4 | Wrong connection of the power supply(positive and negative), the water pump will stop running, and then re-connected, can work normally. | |||||
Built-in pump driver |
| Suitable for non - diving installation, medium below 60 degrees | |
The pump driver is external |
| Submersible installation, high temperature resistance |
五．Installation Drawing
Notice: The pump is not self-priming pump. When install, please make sure there is enough water in pump gland. Meanwhile, the pump must be installed below the liquid level in the tank.

九．Failure and maintenace
Failure and maintenace | |||
Failure | Reason | Solutions | |
1 | Large current and small flow | Impurities in the rotor | injection water from the outlet to clean the inside |
2 | stop working and current is unstable | The rotor is stuck | Clean foreign matter makes rotor stuck |
Stop working and short circuit | Control board is damaged | Change a new pump | |
Stop working and no current | Check the power cord | Reconnect the power | |
3 |
Big noise | Impurities in the pump | Clean the impurities |
Air in the pump and can’t get out | Put the outlet upwards, makes water no air | ||
no water in the pump, dry run | Make sure enough water inside | ||
十．Notice
Notice
1. It is strictly forbidden to use liquids with impurities greater than 0.35mm and ceramic or magnetic particles.
2. If it is not used for long time,make sure water inside pump before power on.
3. Do not let pump dry run
4. If not used for long time, please make sure cord connection correctly.
5. If use in low temperature environment, please make sure the water won’t be frozen or thick.
6. Please check if there is water on connection plug, and clean it before use.
