Webasto self-priming sea water pumps are designed to support marine air-conditioning systems where air intrusion in the water intake is likely—such as during heeling, high-speed cruising, or reversing. These pumps can evacuate air from the intake line, ensuring a consistent water flow to the condenser and preventing system shutdown due to high pressure.

Available models include:

• WB500G – up to 18 l/min, ideal for small units.
• WB1000G – up to 60 l/min, for mid-sized systems.
• WB3800G – up to 120 l/min, for larger units.
• WB8000 and WB10500 – delivering up to 500 and 667 l/min, suitable for professional and luxury yacht installations.

Key features:

• Rugged bronze construction.
• Available in 110V, 230V and 400V variants.
• Ideal for air bubble evacuation in seawater circuits.
• Recommended with BlueCool S and C Series A/C units.
