Fresh water pumps for boats are essential for supplying clean water to sinks, showers, and other onboard systems. Marine pumps are designed to withstand harsh saltwater environments and ensure reliable operation. They come in various types, including diaphragm and centrifugal pumps, tailored for different marine applications.

Size: Typically ranges from 1.5" to 3" in diameter, with flow rates between 5-30 GPM.

Grade: Marine-grade, designed for saltwater and freshwater applications.

Viscosity: Suitable for low-viscosity fluids like water; not designed for high-viscosity oils or fuels.

Buoyancy: Non-buoyant; requires secure mounting to prevent movement.

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

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

Pressure Rating: Typically 30-60 PSI, depending on the model.

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

Seals: Viton or nitrile rubber for durability in marine environments.

Mounting: Compact design for easy installation in bilge or engine compartments.
