The Boat Water Pump Impeller is a crucial component in marine pumps, designed to circulate water for engine cooling and other systems. It features flexible rubber blades that rotate to create suction and move water efficiently. Regular inspection and replacement are essential to ensure optimal performance and prevent overheating in marine engines.

Size: Typically ranges from 2 to 6 inches in diameter.

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

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

Buoyancy: Neutral buoyancy to prevent sinking in water.

Material: Nitrile rubber (NBR), neoprene, or polyurethane for corrosion resistance.

Operating Temperature: -20°C to 120°C (-4°F to 248°F).

Pressure Rating: 50 to 150 PSI, depending on pump design.

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

Chemical Resistance: Resistant to saltwater, oils, and mild chemicals.

Durability: UV-resistant and abrasion-resistant for long service life.

Mounting Type: Keyed or splined shaft for secure attachment.

Compatibility: Designed for centrifugal and jet pump systems.
