🔧 Product Description

The BAYWATT 12V – 1100 GPH automatic bilge pump is fully submersible and designed to run continuously in fresh or saltwater bilges. Its compact format does not reduce its power, and the built-in float switch allows hands-free operation. Ideal for stand-alone use or as a backup to a larger pump.

⚙️ Operation

The pump activates automatically between 40 and 50 mm of water and stops when the level drops to 20–30 mm. Three-wire configuration for automatic and manual override modes:

• Brown-white: connect to +12V for automatic mode (float)
• Brown: connect via a switch for manual override
• Black: connect to battery ground (-)

For manual control, use an ON-OFF-(ON) switch or a pre-wired control panel.

🔌 Wiring Solution

• Pre-wired panel: IBPB model – features an ON-OFF-(ON) switch, buzzer alarm, and indicator light.
• Custom setup: ON-(ON) 22 mm override push button + RGB indicator with customizable symbols.

🔁 Alternative: keep the pump in permanent automatic mode and add a momentary (ON)-OFF push button as a manual bypass. RGB LED: green = pump running, blue = standby, red = manual override.

⛵ Applications & Compatibility

• Motorboats up to 9 meters
• Sailboats up to 30 feet
• Tenders or RIBs with deep bilges

For fresh or saltwater use only. Do not use with hydrocarbons or oily liquids.

⚓ Workshop Note

The 1100 GPH bilge pump is ideal for handling small water ingress (rain, spray, condensation), especially when away from the boat. It can be paired with a higher-capacity pump for increased protection depending on the vessel type.
