SEAFLO 24V 1100GPH 14A Water-Sensing Automatic Low Profile Bilge Pump

Automatic high-flow drainage for narrow 24V bilges

The SEAFLO SFBP2-G1100-14A is a 24V DC, 1100 GPH automatic bilge pump with an integrated water-level sensor. Its narrow low-profile body fits beneath engines, floors and equipment where a conventional upright pump and separate float switch may not fit.

It is suitable for 24V yachts, motorboats, fishing craft and workboats, subject to correct installed capacity and discharge design. The pump turns on and off as the water level rises and falls.

Automatic and service features

• Integrated water-level sensing; no separate float switch required for normal automatic operation.
• Low-profile strainer can drain the bilge to approximately 10 mm.
• Horizontal or vertical mounting with 360-degree rotating discharge.
• Straight hose-barb options for 19, 25 and 29 mm hose plus a 19 mm 90-degree elbow configuration.
• Check valve helps limit discharge-line backflow.
• Snap-fit modular body and replaceable motor cartridge simplify cleaning and service.
• Submersible, ignition-protected construction with moisture-tight seals, stainless-steel shaft and anti-airlock protection.
• Designed to meet CE, RoHS, ISO 8846 and ISO 8849 requirements.

Technical specification

Boat compatibility and installation checks

• For 24V DC boats only; do not connect directly to 12V.
• 1100 GPH is an open-flow figure. Calculate real capacity using vertical lift, hose bore, length, bends and fittings.
• Use reinforced smooth-bore hose matching the selected outlet and provide anti-siphon protection where required.
• Fit correctly sized circuit protection and marine cable for the current and cable run.
• Keep the strainer accessible, prevent debris accumulation and test automatic activation regularly.
• This is the 14A water-sensing version, not the 14B timer-sensing pump or 14C non-automatic pump.
• Package: one 14A pump with discharge/check-valve fittings as supplied; hose, fuse and main wiring are installation items.

Frequently asked questions

Does it require an external float switch?

No. The 14A version has an integrated water-level sensor.

Is the pump suitable for a 12V boat?

No. This product is the 24V model; use the equivalent 12V version.

Will it deliver 1100 GPH after installation?

Actual flow will be lower than the nominal open-flow rating because of lift and plumbing resistance.

Can it be installed horizontally?

Yes, provided water can reach the strainer freely and the installation follows the manufacturer's instructions.
