Introduction
The SEAFLO 24V 14B-Series 1100GPH Narrow Low-Profile Time-Sensing Automatic Bilge Pump is an advanced and space-saving bilge pump designed for efficient water removal in confined bilge areas. With a high-capacity 1100 gallons per hour (GPH) flow rate, this pump delivers powerful performance while its narrow, low-profile design makes it ideal for tight bilge spaces where traditional pumps may not fit. Featuring time-sensing automatic operation, this pump runs in preset intervals to detect and remove water, eliminating the need for a separate float switch. Engineered for marine durability, it withstands harsh conditions and provides long-lasting, maintenance-free performance.
Safety Information
Please read and understand all safety instructions before installing or operating this product. Failure to follow these instructions may result in property damage, serious injury, or death.
- Electrical Safety: Ensure all electrical connections are waterproof and properly insulated. Use appropriate fuse protection for the pump's voltage and current rating. Disconnect power before performing any installation or maintenance.
- Ignition Protection: This pump is ignition-protected, meaning it is designed to prevent ignition of flammable vapors. However, always ensure proper ventilation in bilge areas.
- Submersible Use: The pump is designed for fully submersible operation. Do not operate the pump dry for extended periods, as this can cause damage.
- Proper Installation: Mount the pump securely to prevent movement during operation. Ensure the discharge hose is free of kinks and obstructions.
- Children and Pets: Keep children and pets away from the pump and its electrical connections.
Package Contents
Verify that all items are present in the package:
- 1 x SEAFLO 24V 1100 GPH 14B Series Bilge Pump
- 3 x Hose Fittings
Setup and Installation
Follow these steps for proper installation of your bilge pump:
- Choose Mounting Location: Select the lowest point in the bilge where water collects. The pump's narrow, low-profile design is ideal for tight spaces. Ensure the pump is accessible for maintenance.
- Mount the Pump: Secure the pump to a solid surface using appropriate fasteners. The quick-release strainer base allows for easy snap-off removal for maintenance without detaching the entire pump.
- Connect Discharge Hose: Attach the appropriate hose fitting to the pump's discharge port. The pump features a split-joint design and ports that rotate 360 degrees in every direction, allowing for flexible hose routing. Secure the hose with a marine-grade hose clamp. Route the discharge hose upwards to a thru-hull fitting above the waterline, ensuring a siphon break loop is installed if necessary to prevent backflow.
- Electrical Wiring: Connect the pump to a 24V DC power source. Ensure proper polarity (red wire to positive, black wire to negative). Install an inline fuse (not included) appropriate for the pump's current draw. All connections must be watertight and corrosion-resistant.
- Verify Operation: Once installed, briefly apply power to the pump to ensure it operates correctly and that there are no leaks in the discharge system.

Operating Instructions
The SEAFLO 14B Series Bilge Pump features time-sensing automatic operation:
- Automatic Activation: The built-in electronic sensor activates the pump in timed cycles. It runs for approximately 0.5 seconds every 2.5 minutes to detect the presence of water.
- Water Detection: If water is detected during the 0.5-second check, the pump will continue to run until the water level drops to 1-3 cm (0.4-1.2 inches) off the bottom, effectively removing water from the bilge.
- High Capacity: The pump delivers a powerful 1100 gallons per hour (GPH) flow rate, ensuring efficient water removal.
- Low Power Consumption: Optimized for battery efficiency, the pump minimizes power usage while maintaining strong pumping capacity.
No separate float switch is required for automatic operation.

Maintenance
Regular maintenance ensures optimal performance and longevity of your bilge pump.
- Inspect Regularly: Periodically check the pump, wiring, and discharge hose for any signs of wear, corrosion, or damage.
- Clean Strainer Base: The snap-off strainer base allows for fast and hassle-free maintenance. Disconnect power, then unclip the pump from its base. Remove any debris, leaves, or foreign objects that may have accumulated in the strainer. Rinse with fresh water.
- Check for Air Vents: Ensure the hidden air vents are clear of obstructions to prevent airlock.
- Test Operation: Regularly test the pump's automatic function by pouring water into the bilge to ensure it activates and pumps out water effectively.
Troubleshooting
If your SEAFLO bilge pump is not operating as expected, refer to the following common issues and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not run | No power, blown fuse, loose wiring, motor failure. | Check power supply, replace fuse, inspect and secure wiring connections. If motor failure is suspected, contact support. |
| Pump runs but no water is discharged | Clogged strainer, blocked discharge hose, airlock, pump running dry. | Clean strainer base, clear any obstructions in the hose, check for airlock (ensure air vents are clear), ensure pump is submerged in water. |
| Pump runs continuously | Water level sensor malfunction, continuous water ingress. | Check for constant water source into the bilge. If no water is present, the sensor may be faulty; contact support. |
| Low flow rate | Partially clogged strainer or hose, low voltage, worn impeller. | Clean strainer and hose. Verify correct voltage supply. If issues persist, contact support. |
