Seaflo Heavy Duty Float Switch BS2505

Premium 25A Electromagnetic Control for High-Flow Pumps

The Seaflo BS2505 (05-Series) represents the pinnacle of bilge water management technology. Unlike traditional mechanical switches that often fail due to debris or seal leakage, this heavy-duty unit utilizes electromagnetic activation. By using magnetic force to trigger the pump, the internal mechanism remains completely enclosed and protected from the harsh bilge environment.

ENGINEERED FOR POWER: Specifically designed to handle the high current demands of manual bilge pumps with flow rates exceeding 3000 GPH.

Key Features

  • ✔ Electromagnetic Design: No mechanical seal to leak or fail.
  • ✔ Debris Protection: Enclosed housing prevents clogs.
  • ✔ High Capacity: Rated for a massive 25 Amps.
  • ✔ Mercury-Free: Environmentally friendly and safe.
  • ✔ Quick Installation: Includes detachable base for easy cleaning.

Questions & Answers

Is this a genuine Seaflo part?

Yes, this is an authentic Seaflo 05-Series heavy-duty electromagnetic float switch, supplied in original packaging.

Why do I need a 25A switch instead of a standard 15A or 20A?

High-flow bilge pumps (3000GPH and above) have a significantly higher amp draw upon startup. A standard switch may burn out or fuse closed under these loads; the BS2505 is built specifically to handle that surge safely.

Can this be used in salt water?

Yes. The ABS thermoplastic construction and marine-grade tinned wiring are designed specifically for both fresh and salt water environments.

Note: Ensure the switch is mounted horizontally (max 30° tilt) for optimal electromagnetic float performance. Available via 4boats.co.uk.
