Water pumps for boat docks and marine applications are designed to handle water transfer, bilge pumping, and washdown tasks. These pumps are built to withstand harsh marine environments, including saltwater corrosion and extreme weather conditions. They come in various types, such as centrifugal, diaphragm, and submersible, to suit different marine needs.

Size: Typically ranges from 2" to 6" in diameter for discharge ports.

Grade: Marine-grade materials compliant with ASTM or ISO standards.

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

Buoyancy: Optional buoyant designs for floating applications.

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

Flow Rate: Varies from 500 GPH to 10,000 GPH (gallons per hour).

Pressure Rating: Typically 50-150 PSI depending on model.

Power Source: 12V/24V DC or 110V/220V AC options.

Temperature Range: -20°F to 180°F (-29°C to 82°C).

Seal Type: Mechanical or lip seals for watertight operation.

Weight: 5-50 lbs depending on size and material.

Certifications: USCG, ABYC, or CE compliant for marine use.
