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.
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.
