Sump pumps on boats are designed to remove accumulated water from the bilge or other low-lying areas to prevent flooding. Marine pumps are built to withstand harsh saltwater environments and ensure reliable operation. They come in various types, including manual, automatic, and high-capacity models, tailored for different vessel needs.

Size: Typically ranges from 2 to 6 inches in diameter.

Grade: Marine-grade, corrosion-resistant materials.

Viscosity: Suitable for low to medium viscosity fluids (water, bilge water, light oils).

Buoyancy: Designed to remain operational even when partially submerged.

Material: Constructed from stainless steel, bronze, or high-impact plastic for durability.

Flow Rate: Varies between 500 to 5,000 gallons per hour (GPH).

Power Source: 12V or 24V DC, compatible with marine electrical systems.

Pressure Rating: Typically 10 to 50 PSI, depending on model.

Temperature Range: Operates in -20°F to 140°F (-29°C to 60°C) conditions.

Seal Type: Mechanical or lip seal for watertight operation.

Weight: Lightweight, usually 2 to 10 lbs, for easy installation.

Certifications: Meets ABYC, USCG, and ISO marine standards.
