Sailboat water pumps are essential marine devices designed to move water efficiently within a vessel. Marine pumps ensure proper bilge drainage, freshwater supply, and cooling systems for engines. They are built to withstand harsh saltwater conditions and provide reliable performance.

Size: Typically ranges from 1.5 to 3 inches in diameter for standard marine pumps.

Grade: Marine-grade materials, often meeting ABYC or ISO standards.

Viscosity: Suitable for fluids with viscosities up to 1000 cSt (centistokes).

Buoyancy: Not applicable as pumps are fixed installations; float switches may have buoyancy ratings.

Material: Corrosion-resistant materials like bronze, stainless steel, or reinforced plastics.

Flow Rate: Varies from 5 to 50 GPM (gallons per minute) depending on model.

Power Source: 12V or 24V DC for electric models; manual options available.

Pressure Rating: Typically 30-100 PSI for standard marine pumps.

Temperature Range: -20°C to 80°C (-4°F to 176°F) for most models.

Seal Type: Mechanical seals or lip seals for watertight operation.

Mounting: Flange or direct bolt-on mounting for secure installation.

Weight: 2-10 lbs (0.9-4.5 kg) depending on size and material.
