The raw water pump for boats is a marine pump designed to circulate seawater for engine cooling and other systems. It ensures efficient heat transfer and prevents overheating in marine engines. Typically made of corrosion-resistant materials, it is essential for reliable boat operation.

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

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

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

Buoyancy: Designed to be neutrally buoyant or corrosion-resistant for submerged use.

Material: Constructed from bronze, stainless steel (316L), or reinforced thermoplastics for saltwater resistance.

Flow Rate: Varies between 10 GPM to 500 GPM (gallons per minute).

Pressure Rating: Typically 50 PSI to 150 PSI, depending on the model.

Impeller Type: Closed, semi-open, or vortex design for debris handling.

Seal Type: Mechanical seals or lip seals for leak-proof operation.

Power Source: Electric (12V/24V DC or 110V/220V AC) or engine-driven.

Temperature Range: -10°C to 80°C (14°F to 176°F) for standard models.

Certifications: Often meets ABYC, USCG, or CE marine safety standards.
