Typical Applications
4. Installation & Setup
Proper installation is crucial for the optimal performance and longevity of your bilge pump. Ensure all connections are secure and watertight.
4.1 Mounting
- Mount the pump in the lowest part of the bilge where water collects.
- Ensure the pump is securely fastened to a solid surface using appropriate fasteners.
- The snap-off strainer base allows for easy mounting and removal for maintenance.
4.2 Wiring
- Connect the pump to a 12V or 24V DC power source, matching the pump's voltage (SFBP1-G2000-01 for 12V, SFBP2-G2000-01 for 24V).
- Use marine-grade blocked wiring (14 AWG, 1m long leads are provided).
- Install an appropriate fuse (14.0 A for 12V, 8.0 A for 24V) in the positive lead as close to the power source as possible.
- Ensure all electrical connections are waterproof and protected from corrosion.
- The pump is non-automatic and requires an external panel switch or float switch for activation.
4.3 Plumbing
- Connect a 1-1/8" (29mm) ID hose to the pump's outlet barb.
- Route the discharge hose upwards to a through-hull fitting, ensuring a continuous rise to prevent back-siphoning.
- Secure the hose with hose clamps at both the pump and the through-hull fitting.
5. Operation
The SEAFLO 2000GPH Bilge Pump is a non-automatic model, meaning it requires manual or external switch activation.
- Manual Operation: Activate the pump using a panel switch connected to the power source.
- Automatic Operation (with external switch): For automatic operation, install a compatible float switch (not included). The float switch will detect water levels and activate the pump when necessary.
- Ensure the pump is fully submerged in water for optimal performance.
- Monitor the pump's operation to ensure it is effectively removing water.
6. Maintenance
Regular maintenance will extend the life of your bilge pump and ensure reliable operation.
6.1 Cleaning the Strainer Base
- Periodically check the strainer base for debris such as leaves, hair, or other foreign objects that could clog the pump.
- To clean, simply snap off the strainer base from the pump body.
- Remove any accumulated debris and rinse the strainer.
- Snap the strainer base back into place, ensuring it is securely attached.
6.2 General Inspection
- Inspect wiring for any signs of wear, fraying, or corrosion.
- Check hose connections for leaks and ensure clamps are tight.
- Verify that the pump is securely mounted.

7. Troubleshooting
If your bilge pump is not operating correctly, refer to the following common issues and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not run | No power, blown fuse, faulty switch, loose wiring connection. | Check power supply, replace fuse, test/replace switch, secure wiring. |
| Pump runs but no water is discharged | Clogged strainer/impeller, airlock, kinked or blocked discharge hose. | Clean strainer/impeller, clear airlock by tilting pump, check and clear hose. |
| Pump runs continuously | Faulty float switch (if installed), back-siphoning, leak in discharge line. | Inspect/replace float switch, ensure proper hose routing with loop, check for leaks. |
| Reduced flow rate | Partially clogged strainer/impeller, low voltage, worn impeller. | Clean strainer/impeller, check battery voltage, inspect impeller for wear. |
8. User Tips
- Always ensure the pump's voltage matches your boat's electrical system (12V or 24V) to prevent damage.
- Consider installing a non-return valve in the discharge line to prevent water from flowing back into the bilge.
- For boats, regularly check the bilge for debris and keep it clean to minimize pump clogging.
- If using a float switch for automatic operation, test it periodically to ensure it activates correctly.
