| 2 | Rated Voltage | 12V DC | 24V DC | 24V DC | 36V DC | |
| 3 | operating voltage range: | 5-12V | 5-30V | 5-26V | 5-40V | Within this range, the pump can work normally |
| 4 | Rated current: | 3.5A(4.5A) | 1.4A(2.2A) | 2.7A(3.3A) | 1.8A(2.2A) | Closed outlet current (open pumping current) |
| 5 | Input Power: | 42W(55W) | 42W(54W) | 65W(80W) | 65W(80W) | Closed outlet power (open pumping power) |
| 6 | Max. Flow: | 2100L/H | 2100L/H | 2700L/H | 2700L/H | The flow of water when there is no takeover |
| 7 | Max.Head | 10M | 10M | 14M | 14M | Static head |
| 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 | 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 | ||
