Ballast pumps for boats are specialized marine pumps designed to transfer water in and out of ballast tanks to stabilize vessels. These pumps ensure proper weight distribution, improving safety and performance during navigation. They are built to withstand harsh marine environments and resist corrosion.

Size: Typically ranges from 1.5 to 4 inches in diameter.

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

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

Buoyancy: Designed to be neutrally buoyant or slightly positive in water.

Material: Constructed from corrosion-resistant materials like stainless steel, bronze, or reinforced plastics.

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

Power Source: Electric (12V/24V DC) or hydraulic-driven options.

Pressure Rating: Typically 10 to 100 PSI, depending on the model.

Temperature Range: Operates between -20°C to 80°C (-4°F to 176°F).

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

Weight: Ranges from 5 to 50 lbs, depending on size and material.

Installation: Can be mounted inline or submerged, depending on design.
