Laguna Automatic Bilge Pump 750 GPH, 12V

Meet the Laguna Automatic Bilge Pump 750 GPH, 12V—a marine-grade solution engineered for reliable, hands-off bilge management. With its built-in Laguna Switch sensing system, this pump runs automatically without an external float switch, simplifying wiring and reducing potential points of failure while keeping your bilge dry in rough seas or heavy rain.

Why this Laguna bilge pump stands out

• Automatic operation without a float switch: The integrated Laguna Switch detects water presence and starts pumping automatically, delivering peace of mind when you need it most.
• Water-cooled motor: Designed for sustained performance in confined or hot engine spaces, helping extend motor life and maintain efficiency.
• Removable clip-on basket and high-impact plastic housing: Easy maintenance and rugged durability for marine environments.
• Italian engineering, ISO 8846 MARINE: Built to withstand harsh marine conditions with quality and reliability you can trust.
• Compact, submersible design with a 750 GPH capacity and low draw: 12VDC operation at ~3A, fused at 2.5A for safe, efficient performance.
• Ready-to-install hose connection: 3/4" (19 mm) hose with practical dimensions (150 x 78 x 100 mm) for versatile mounting in tight bilge spaces.

Who is this pump ideal for?

Boaters with mid-size or small craft who want dependable, maintenance-friendly bilge drainage without adding complexity. It’s an excellent choice for sailboats, motor yachts, fishing boats, and recreational vessels that benefit from automatic, no-fuss bilge management. It also serves as a reliable backup on vessels where the bilge area is prone to pooling during heavy seas or rainstorms.

Key use cases

• Automatic bilge drainage in engine rooms and re-boarding compartments where space is at a premium.
• Primary bilge pump in boats that prefer a simple, integrated solution without external float switches.
• Emergency drainage during rough weather to prevent water from accumulating and affecting buoyancy or equipment.
• Maintenance-friendly setup in salty or humid environments where durable, long-life components matter.

How it works

Submersible and resilient, the Laguna automatic bilge pump sits in your bilge and monitors water presence with its built-in sensing system. When water is detected, the pump starts automatically, expelling water through a standard 3/4" hose. Since there’s no float switch to service or replace, you get a streamlined installation and fewer parts to fail over time.
