Pump for a boat, or marine pumps, are specialized devices designed to move water or other fluids within a vessel. They are essential for bilge drainage, cooling systems, and freshwater supply. Marine pumps are built to withstand harsh saltwater environments and ensure reliable operation.

Size: Typically ranges from 1.5 to 6 inches in diameter, depending on the application.

Grade: Marine-grade pumps designed for saltwater and freshwater environments.

Viscosity: Suitable for fluids with viscosities up to 500 cSt (centistokes).

Buoyancy: Not applicable as pumps are fixed or mounted; buoyancy depends on the boat's design.

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

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

Power Source: Electric (12V/24V DC or 110V/220V AC) or manual operation.

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

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

Seal Type: Mechanical or lip seals for watertight operation.

Mounting: Can be inline, submersible, or surface-mounted.

Certifications: Often meets ABYC, ISO, or CE marine standards.
