| 2 | Rated Voltage: | 12V DC | 12V DC | 24V DC | 24V DC | |
| 3 | Working voltage range: | 5-12V | 5-12V | 5-28V | 5-28V | The pump can out put constant power when the voltage is higher than rated voltage. |
| 4 | Rated Current: | 0.75A | 1.6A(2A) | 1A(1.3A) | 1.3A(1.7A) | Closed outlet current(open outlet current) |
| 5 | Input Power: | 7W(9W) | 20W(25W) | 24W(30W) | 30W(40W) | Closed outlet power(open outlet power) |
| 6 | Max. Flow rate: | 500L/H | 700L/H | 750L/H | 850L/H | Open outlet flow |
| 7 | Max. Head: | 4M | 8M | 10M | 12M | Static lift |
| 8 | Min. power supply: | 12V-1A | 12V-2A | 24V-2A | 24V-2A |
| 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 | 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. | |
| Built-in pump driver | |
Suitable for non - diving installation, medium below 60 degrees | |
| The pump driver is external | |
Submersible installation, high temperature resistance | |
| Failure and maintenance | |||
| 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 | ||
