SEAFLO 24V 1100GPH 13A Non-Automatic Submersible Bilge Pump

24V non-automatic 1100 GPH bilge pump

The SEAFLO SFBP2-G1100-13A is a compact, cartridge-style submersible bilge pump for high-flow nuisance-water removal. It is non-automatic and must be controlled through a manual panel switch or a separate float/electronic bilge switch. The quick-connect split joint allows the motor cartridge to be removed without disconnecting the base or discharge plumbing.

Suitable boats and bilge arrangements

• 24V motor yachts, sailing yachts, cruisers, fishing boats and workboats with a bilge installation suitable for 1100 GPH and a 25/29 mm outlet.
• Engine-room, keel, lazarette and machinery-space bilges requiring a serviceable cartridge pump.
• Suitable as a manually controlled pump or for automatic operation with a correctly rated external water-level switch.
• May be used as one part of a redundant bilge system; required total capacity depends on vessel risk, hose losses, alarm and power supply.
• Not for fuel, oil, sewage or unattended operation without a suitable external switch.

Verified technical specification

Compatibility and installation checks

• Confirm a 24V DC supply and that a non-automatic pump is required.
• Match the supplied outlet fitting to 25 or 29 mm hose and keep lift, length and bends as low as practical.
• Use the correct fuse, marine cable and manual or automatic external switch in accordance with the pump instructions.
• Route discharge above the loaded waterline and provide anti-siphon protection where required.
• Keep the cartridge release and strainer accessible for cleaning and emergency replacement.
• Package: one SEAFLO 13A pump assembly with the supplied discharge fitting/check valve. Hose, switch, fuse, alarm and through-hull are separate.

Frequently asked questions

Does the 13A pump start automatically?

No. It requires a manual switch or a separate compatible float/electronic bilge switch.

Can I replace the motor without removing the hose?

The 13A split quick-connect design allows the motor cartridge to be removed while the base and plumbing remain installed.

Can it be connected to a 12V system?

No. This specific model is rated for 24V DC.

Will it deliver 1100 GPH at maximum head?

No. 1100 GPH is the nominal open-flow rating; discharge falls as head and plumbing resistance increase.
