SEAFLO 24V 1100GPH 01 Series Non-Automatic Bilge Pump Boat

24V high-capacity non-automatic bilge pump

The SEAFLO SFBP2-G1100-01 is a fully submersible 24V centrifugal bilge pump rated at 1100 GPH. It has no built-in water sensor: it must be operated by a manual panel switch or a separate float/electronic bilge switch. A snap-off strainer base gives access for cleaning and service.

Suitable boats and bilge arrangements

• 24V motor yachts, sailing yachts, cruisers, fishing boats and workboats needing a compact 29 mm outlet bilge pump.
• Useful in engine-room, keel, lazarette or machinery-space bilges where the capacity and discharge route are appropriate.
• May be used as a primary nuisance-water pump or an additional pump in a redundant bilge arrangement.
• Do not select by boat length alone; assess water-ingress risk, hose/head losses, battery supply, alarm and redundancy.
• Not for fuel, oil, sewage or continuous dry operation.

Verified technical specification

Check before ordering and installing

• Confirm the vessel is 24V DC and that the mounting space and 29 mm hose route are suitable.
• Keep the discharge run short and smooth; vertical lift and plumbing resistance reduce actual flow.
• Fit the correct fuse, cable and manual/automatic switch according to the pump instructions and cable length.
• Route the outlet above the loaded waterline and fit anti-siphon protection where required.
• Keep the strainer accessible and test the pump and high-water alarm regularly.
• Package: one SEAFLO pump. Hose, switch, fuse holder, alarm and through-hull are separate installation parts.

Frequently asked questions

Does it start automatically?

No. It requires a manual switch or separate float/electronic water-level switch.

Can it be used on 12V?

No. This model is rated for 24V DC.

Will it deliver 1100 GPH at 4 metres of lift?

No. The 1100 GPH figure is the nominal open-flow rating; flow falls as head and restriction increase.

Is it automatically suitable for every large boat?

No. Bilge-pump capacity and redundancy must be assessed for the individual vessel and installation.
