Gisafai 12V Submersible Bilge Pump 1100GPH, Pair 29mm Outlet Stainless-Steel Marine-Grade

These two 1100 GPH 12V pumps combine stainless-steel and marine-grade plastic construction with a compact footprint and a 29 mm outlet, delivering dependable bilge evacuation for fishing boats, runabouts, cruisers, yachts and even caravans. Built for routine use and straightforward maintenance, the set balances flow capacity and head height so you can clear bilge water without complicated plumbing or frequent service.

How much water can these pumps move and how high can they lift it?

Each Gisafai pump is rated at 1100 gallons per hour (GPH) at zero lift and maintains effective flow to a practical head before performance declines. The maximum head is approximately 13 feet (4 meters), which suits typical bilge drainage and low-to-mid elevation discharges.

• Flow capacity: 1100 GPH per pump for fast bilge clearing
• Maximum head: around 13 ft / 4 m for elevated discharge
• Outlet diameter: 1-1/8" (29 mm) for common hose fittings

Are these pumps easy to install and keep working?

Installation is straightforward: connect the 12V power, secure the outlet hose to the 29 mm fitting, and mount the pump in the bilge area. Routine maintenance is minimal — periodic debris clearing and a quick visual inspection help preserve performance and avoid clogs.

• 12V DC wiring compatible with typical boat electrical systems
• Quick-connect hose fitting size simplifies plumbing
• Removable strainer and simple exterior for easy cleaning

What materials and build features improve durability in marine environments?

Gisafai pumps blend stainless-steel components with robust marine-grade plastics to resist corrosion and mechanical wear from regular bilge use. That mix of materials helps the pumps withstand salt spray, moisture and the vibration common aboard small craft.

• Stainless steel parts for corrosion resistance
• Durable plastic housings to reduce weight and resist impact
• Sealed motor assembly designed for submersible operation

How can I use these pumps across different boat and vehicle types?

The pumps are engineered to be versatile: they fit into a variety of bilge layouts and can serve boats, yachts, inflatables, and utility vehicles like caravans when 12V power is available. Their compact profile and standard outlet size make them adaptable to both new installations and replacements.

• Suitable for fishing boats, runabouts, cruisers and yachts
• Works in caravans and similar 12V applications with bilge needs
• Pairing two pumps gives redundancy or increased combined flow

Who is this for: The Gisafai 2-pack of 1100 GPH 12V submersible bilge pumps is aimed at boat owners, fleet managers and DIY marine technicians who need a cost-effective, easy-to-install bilge pumping solution.
