Product Description

This submersible automatic bilge pump is designed for small and medium-sized boats requiring reliable water evacuation from the bilge. It is suitable for rainwater, spray, condensation and small water ingress when the boat is moored or left unattended.

The integrated float switch removes the need for a separate external float switch. This saves space, reduces wiring complexity and makes the installation easier in compact bilge compartments. The pump can be wired for permanent automatic operation, with an optional manual override switch for direct control from the dashboard.

Installation note: for unattended bilge protection, the automatic feed should be protected by a fuse or circuit breaker and connected so the pump can still operate when the main battery switch is turned off. Keep the protection device close to the battery positive terminal.

Operation

The pump starts automatically when the water level reaches approximately 40–50 mm and stops when the level drops to approximately 20–30 mm. The three-wire configuration allows both automatic mode and manual override.

Black wire: connect to battery negative (-)
Brown-white wire: connect to +12V for automatic float switch mode
Brown wire: connect through a switch for manual override

For manual control, use a marine ON-OFF-(ON) switch, a momentary override push button or a dedicated bilge pump control panel.

Wiring Solution

Pre-wired control panel: use the IBPB bilge pump control panel with ON-OFF-(ON) switch, buzzer alarm and LED indicator.

Custom dashboard setup: combine an ON-(ON) 22 mm override push button with an RGB indicator push button for a clean dashboard installation with customizable symbols.

Alternative wiring: keep the pump in permanent automatic mode and add a momentary (ON)-OFF push button as a manual bypass. The RGB indicator can be used as visual feedback: green = pump running, blue = standby, red = manual override.

Applications & Compatibility

Motorboats up to 9 meters
Sailboats up to 30 feet
RIBs, tenders and small fishing boats
Backup bilge pump installation on larger vessels
Freshwater or saltwater bilge compartments

Workshop note: a 1100 GPH bilge pump is well suited for rainwater, spray and small water ingress. For boats exposed to heavier water entry, it can be combined with a higher-capacity bilge pump or a separate high-water alarm.

For water evacuation only. Do not use this pump with fuel, oil, hydrocarbons, solvents or flammable liquids. Avoid prolonged dry running.
