Key features

• Electronic Sensing technology detects bilge water levels and triggers the pump precisely when needed.
• 12V DC, 15A capacity supports most standard bilge pumps.
• Rugged, maintenance-free design: free of moving parts that can jam, wear, or fail.
• Ignition protected and RoHS compliant for marine safety and environmental compliance.
• Proprietary sensing distinguishes water from splashes, foam, sludge, and chemicals to prevent unnecessary cycling.
• Fully sealed electronics protected from water and chemical damage.
• Flexible mounting options that add convenience: floor of the bilge, directly to a stringer wall, or alongside the pump basket without extra components or brackets.
• Direct compatibility with all competitive products, simplifying upgrades or replacements.

The S3 Series is engineered for reliable operation in any bilge water mixture, ensuring your pump only runs when there’s real bilge water and stopping unnecessary cycling when conditions change. Its sealed electronics prevent corrosion and keep performance consistent even in challenging marine environments.
