5. Setup & Installation
Follow these steps for proper installation of your SEAFLO submersible pump:
- Power Source: Connect the pump to a stable 12V DC power source. Ensure the polarity is correct (red wire to positive, black wire to negative). The pump comes with 3 ft (1m) of 18 AWG wire leads.
- Placement: The pump is fully submersible. Place it directly into the water tank or sump where it will operate. Ensure it is positioned vertically and securely to prevent movement during operation.
- Outlet Connection: Connect a 1/2" (12mm) hose or pipe to the pump's outlet. Secure the connection with a hose clamp if necessary to prevent leaks.
- System Integration: Integrate the pump into your existing water system (e.g., galley sink, RV water system, sump discharge). Ensure there are no kinks or obstructions in the outlet hose.

6. Operating Instructions
Once installed, operating the SEAFLO pump is straightforward:
- Activation: Apply 12V DC power to the pump. The pump will begin to transfer water immediately.
- Continuous Operation: This pump is designed for intermittent duty. It can operate continuously for up to 30 minutes per cycle. Allow for a cool-down period after 30 minutes of continuous use to ensure longevity.
- Flow Rate: The pump delivers a flow rate of 4.22 GPM (16 LPM) at 12V DC, capable of efficiently moving water for various needs.
- Vertical Lift: The pump can lift water up to 18 feet (6m) vertically, making it suitable for applications requiring water to be moved against gravity.
7. Maintenance
The SEAFLO submersible pump is designed for minimal maintenance due to its dry-sealed motor with permanent lubrication. However, regular checks can ensure optimal performance:
- Inlet Check: Periodically inspect the pump's inlet for any debris or obstructions that might impede water flow. Clean as necessary.
- Hose Connections: Ensure all hose connections remain tight and free of leaks.
- Electrical Connections: Verify that electrical connections are secure and free from corrosion.
- Storage: If storing the pump for an extended period, ensure it is clean and dry. Store in a cool, dry place.
8. Troubleshooting
If you encounter issues with your SEAFLO pump, refer to the following troubleshooting guide:
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not run | No power or incorrect voltage | Check 12V DC power supply and connections. Ensure correct polarity. |
| Blown fuse or tripped breaker | Check and replace fuse or reset breaker in the power circuit. | |
| Motor failure | Contact customer support if power is confirmed and pump still does not run. | |
| Low flow or no water output | Inlet clogged with debris | Remove pump and clear any obstructions from the inlet. |
| Kinked or obstructed outlet hose | Inspect the entire length of the outlet hose for kinks or blockages. | |
| Insufficient water level | Ensure the pump is fully submerged in water. | |
| Pump runs but no water | Air lock | Ensure the pump is fully submerged and the system is primed. Briefly lift and re-submerge the pump to release trapped air. |
| Excessive noise or vibration | Pump not securely placed | Ensure the pump is stable and not vibrating against tank walls or other surfaces. |
| Internal damage | If noise persists and performance is affected, contact customer support. |
