Amarine Made 12V 1100 GPH Submersible Bilge Pump with Internal Float Switch — Ignition-Protected, Corrosion-Resistant

The Amarine Made 12V 1100 GPH Auto Submersible Bilge Pump is a compact, ignition-protected marine pump with an internal float switch that automatically removes bilge, basement, or standing water.

This compact automatic pump combines a high-output 1100 GPH rating with a built-in float switch and corrosion-resistant construction, making it suitable for boats, emergency sump tasks, and general water removal. It runs on 12V, draws only 3.2A, and is designed for long life with a water-cooled motor and stainless-steel shaft.

How does this pump activate and stop on its own?

The pump uses an internal float switch and an electronic reed sensor to detect rising water. When the water reaches the trigger point, the motor runs; once the level drops below the shutoff point, it stops — no external float needed.

• Built-in float switch: automatic on/off
• Integrated test button allows quick function checks
• Electronic reed sensor prevents false activations
• Can be wired to a manual switch panel for override

What are the performance specs and typical output?

This model delivers up to 1100 gallons per hour at 12V while drawing about 3.2 amps, providing fast removal of standing water in tight spaces. The pump can handle a 4.0-meter head and has a 29mm (1-1/8") outlet for common marine hoses.

• Flow rate: 1100 GPH
• Voltage: 12V DC, current: 3.2A
• Maximum head: 4.0 meters
• Outlet diameter: 29mm (1-1/8") and 1M wire lead

Is it durable and suitable for saltwater use?

The pump is built from rustproof materials with a stainless-steel shaft and high-impact thermoplastic housing to resist corrosion. Water-cooled motors, moisture-tight seals, and anti-airlock protection extend service life in both saltwater and freshwater environments.
