SEAFLO 12V Electric Marine Submersible Bilge Pump 1100GPH Anti-Airlock Corrosion-Resistant Modular Quick-Connect Design

Frequently Asked Questions

Is this bilge pump suitable for Australian boats and marine conditions?

Yes, absolutely. The SEAFLO 12V Bilge Pump is specifically designed for marine environments and built to handle Australian saltwater conditions. It features a corrosion-resistant stainless steel motor shaft, moisture-tight seals, and marine-grade silicon-blocked, tin-coated wiring that resists rust and degradation. It's also certified to ISO 8846 and ISO 8849 standards, which are international marine safety standards. Whether you're in saltwater or freshwater, this pump is engineered to perform reliably in harsh Australian coastal conditions.

What's the difference between this 1100GPH model and the smaller 600GPH or 800GPH options?

The 1100GPH model is the most powerful option in the SEAFLO range, meaning it can evacuate water 1.5 to 1.8 times faster than the smaller models. All three models (600GPH, 800GPH, and 1100GPH) share the same quality features like anti-airlock protection, quick-connect design, and corrosion-resistant construction. Choose the 1100GPH if you have a larger bilge area, expect heavy water ingress, or want maximum pumping capacity. The 1100GPH draws 4.0A at 12V, so it's still energy-efficient despite its higher flow rate.

Do I need to buy a float switch separately, or is one included?

This is a non-automatic pump, which means it doesn't include a built-in automatic float switch. You'll need to activate it manually via a panel switch, or purchase a separate SEAFLO float switch to automate operation. The non-automatic design gives you more control over when the pump operates, which some boat owners prefer for precision management of bilge water. If you want automatic operation, you can easily add a compatible SEAFLO float switch to your setup.

How quickly can I get this pump delivered, and what are the return options?

If you're not completely satisfied, we offer a 30-day returns policy, so you can purchase with confidence. Simply contact us if you need to return or exchange the pump within 30 days of purchase. This gives you plenty of time to test it on your boat and ensure it's the right fit for your needs.

Will this pump fit my boat's existing bilge setup, or do I need to modify anything?

The SEAFLO pump has flexible installation options designed to fit most setups. It features a 1" (25mm) and 1 1/8" (29mm) outlet diameter, allowing compatibility with standard Australian marine plumbing fittings. The pump also works with both straight and 90° fittings, so you can accommodate various installation angles without major modifications. The threaded discharge and modular quick-connect design with split joint mean you can remove and install the pump without disconnecting the base or plumbing—making it easy to adapt to your existing bilge system.

How loud is this pump, and will it disturb me while I'm on the boat?

The SEAFLO 1100GPH is designed for quiet operation, so it won't create excessive noise while running. Combined with its energy-efficient 12V motor that draws only 4.0A, it's one of the quieter options in its class. The low amp draw also means less strain on your boat's battery system, so you can run it frequently without significant power drain. It's a good choice if you want reliable water evacuation without the noise distraction.

What makes the anti-airlock feature important for a bilge pump?

Air bubbles trapped in the pump or plumbing lines can prevent the pump from operating effectively, even if water is present in the bilge. The SEAFLO's advanced anti-airlock protection prevents these air pockets from forming, ensuring uninterrupted water flow every time you activate the pump. This is especially important in Australian boats where rapid water ingress can occur, and you need the pump to perform reliably without airlock failures. It's one of the key features that sets this pump apart from cheaper alternatives.
