Xztrdi 12V 1100GPH Automatic Marine Bilge Pump — Built-In Float Switch, 1-1/8" Outlet, Corrosion-Resistant

The Xztrdi 12V 1100GPH Automatic Marine Bilge Pump is a self-contained submersible bilge pump with an internal float switch that automatically evacuates bilge water through a 1-1/8" (29mm) outlet.

This compact, heavy-duty pump is built for boat and yacht bilges where reliable, automatic water removal matters. It combines a water-cooled motor and corrosion-resistant components for durable operation in marine environments. Designed to remain idle until the float activates, the unit minimizes battery drain and simplifies installation by eliminating the need for a separate float switch.

How quickly does this pump remove bilge water?

The pump moves up to 1100 gallons per hour (GPH) at 12 volts, making it suitable for routine bilge clearance and managing moderate ingress. Performance will vary with head height and hose layout, so expect lower flow at higher discharge elevations.

• Rated flow: 1100 GPH (at optimal conditions)
• Maximum recommended head: 2.5 meters
• Outlet diameter: 28.5 mm (1-1/8") for standard hose fittings
• Power draw: approximately 3.8 A at 12 V

What makes installation and operation simple aboard a boat?

Installation is straightforward because the pump includes a built-in float switch, removing the need to mount or wire a separate float. A one-meter wire lead and a snap-off strainer simplify placement and routine cleaning, while the submersible design fits inside most bilge wells.

• Built-in float switch: automatic on/off with rising water
• 1 m wire lead for connection to a 12 V source or marine fuse panel
• Snap-off strainer for easy debris removal and maintenance
• Compact dimensions: 155 x 90 x 115 mm to suit confined bilge spaces

How durable and maintenance-friendly is the pump?

The Xztrdi pump uses a water-cooled motor and corrosion-resistant materials for extended service in wet, salty conditions. Its thermoplastic housing and stainless steel shaft resist rust, while moisture-tight seals and anti-airlock design reduce the likelihood of motor damage from intermittent operation.

• Thermoplastic ABS housing for high-impact resistance
• Stainless steel shaft to resist corrosion
• Water-cooled motor and anti-airlock design for reliability
• Moisture-tight seals to protect internal components

Will this pump be energy efficient for long-term use?

The pump is designed to remain completely off until the internal float switch activates, so it does not draw power when the bilge is dry. When it runs, the motor uses about 3.8 amps at 12 volts, providing a balance of flow and reasonable energy consumption compared with manual pumps.

• Zero standby power draw until float engages
• Operating current: 3.8 A at 12 V
• Automatic shutoff when water level drops to protect battery life
• Snap-off strainer reduces clogging and motor strain

Who is this for: Boat owners, small yacht crews, and marine maintenance professionals who want a compact, automatic bilge pump that is easy to install and built to withstand marine conditions. It’s suited for sailboats, powerboats, tenders, and workboats where a self-activating, low-maintenance pump with a 1-1/8" outlet and reliable stainless components is desired. Consider pump placement, discharge routing, and battery capacity to ensure optimal performance for your vessel.
