Sea water pumps for boats, also known as marine pumps, are designed to move seawater efficiently for cooling, bilge drainage, or washdown systems. These pumps are built to withstand harsh marine environments, including corrosion and high salinity. They come in various types, such as centrifugal, diaphragm, or impeller pumps, tailored for specific marine applications.
Size: Typically ranges from 1.5" to 6" in diameter, depending on flow rate requirements.
Grade: Marine-grade materials, often compliant with ASTM, ISO, or DNV standards.
Viscosity: Designed to handle seawater with viscosity similar to water (1-1.5 cP at 20°C).
Buoyancy: Not applicable for pumps, but housings may be buoyant if made from lightweight polymers.
Material: Bronze, stainless steel (316L), or reinforced thermoplastics for corrosion resistance.
Flow Rate: Varies from 10 GPM to over 1000 GPM, depending on pump type and application.
Pressure Rating: Typically 50-150 PSI for standard marine pumps.
Power Source: Electric (12V/24V DC or 110V/220V AC) or engine-driven.
Seal Type: Mechanical seals or lip seals, often silicon carbide or tungsten carbide for durability.
Temperature Range: -10°C to 80°C, with high-temperature variants available.
Impeller Type: Closed, semi-open, or open, usually in bronze or composite materials.
Mounting: Flange, baseplate, or direct coupling configurations.
Certifications: Often meets ABS, Lloyds, or USCG standards for marine use.
