Intelligent Electronic Switch for Bilge Pumps up to 40 Ah

Why choose the Seymo Automatic Bilge Switch?

The only electronic switch with advanced modular technology

Unlike most switches on the market, where the sensor and electronics form a single unit submerged in the bilge—leading to leaks, costly breakdowns, and the need to replace the entire unit—Seymo revolutionizes the system by separating the processing unit (CPU) from the sensor.

Our experience in the marine industry demonstrates that keeping the electronics away from wet areas ensures dramatically greater durability. While the CPU is installed in a high, dry location, the robust sensor remains in the bilge, eliminating water-related failures.

Seymo's Competitive Advantages

Intelligent modular design: Independent CPU, protected from moisture.

Economical maintenance: Post-warranty technical service with a flat repair rate of just €20.

Replaceable sensor: If the sensor is damaged, it can be replaced independently for just €12.

No moving parts: A completely sealed sensor prevents mechanical wear and the clogging common with traditional buoys.

Maximum resistance: Manufactured with corrosion-resistant AISI 316 stainless steel components, protected against solvents and aggressive bilge fluids.

The most powerful on the market, it supports bilge pumps up to 40 amps.

Technical Specifications and Performance

Compatibility: Suitable for pumps up to 40 Ah.

Voltage: Available in 12V or 24V versions (depending on selection).

Efficient consumption: Negligible standby consumption of only 0.0017 mA.

Versatility: Optimal performance in both fresh and salt water. Intelligent Operating Cycle

1. Start-up Self-Diagnosis (Automatic Test)

When the unit is connected to power, the system performs an automatic test of the indicator LEDs (low battery, pump running, buzzer, etc.) and the bilge pump:

Start-up Test: The pump activates for 2 seconds so the user can audibly verify its correct operation or detect any blockages.

Battery Monitoring: The voltage is monitored every 10 minutes. If the battery drops below 10V, an audible warning (beep every 2 seconds) is activated, and the low battery LED illuminates.

2. Anti-Heeling Management and Efficient Bilge Pumping

Safety Delay (7-8 seconds): Prevents the pump from turning on unnecessarily due to intermittent water movement caused by the boat's roll or heel.

Draining Cycle (15 seconds): Once the level is confirmed, the pump operates for 15 seconds. The pump operation LED illuminates, and a 2-second beep sounds to ensure complete bilge drainage.

Continuous Flow Alarm: If the sensor continues to detect water after the first cycle, the pump will continue operating. The LED will remain illuminated, and a 5-second beep will sound every 15 seconds as a warning to indicate a higher than normal water flow. The system will only stop when the bilge is dry or if the battery voltage drops below the 10V safety threshold.
