COMMODORE 1100 GPH 12V Automatic Electronic Bilge Pump – Dual-Outlet Compatibility

The COMMODORE CM-B31-1100B 1100 GPH Automatic Electronic Bilge Pump features an internal electronic water-sensing system that checks for water every 2.5 minutes and activates only when needed—eliminating the need for a float switch. Equipped with dual outlet fittings (3/4" and 1-1/8"), the pump adapts easily to existing plumbing systems. A built-in check valve prevents backflow, while the threaded discharge and quick-connect wiring allow fast servicing. Designed with a stainless-steel motor shaft, moisture-tight seals, and a submersible ignition-protected motor, this pump meets CE, RoHS, ISO 8846, and ISO 8849 marine standards.

Key Features

  • Automatic electronic water-sensing system eliminates need for float switch
  • Includes 3/4" and 1-1/8" outlet fittings for universal compatibility
  • Internal check valve prevents backflow into the bilge
  • Quick-connect wiring and threaded outlet simplify servicing
