Replacing the impeller on inboard marine pumps involves removing the pump housing to access the worn impeller. Carefully install the new impeller, ensuring the vanes are correctly aligned and lubricated. Reassemble the pump, test for leaks, and verify proper water flow to complete the process.

Size: Typically ranges from 2 to 12 inches in diameter, depending on pump model and application.

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

Viscosity: Suitable for fluids with viscosities ranging from 1 to 1000 cSt (water to heavy oils).

Buoyancy: Neutral buoyancy in water; material density balanced for submerged operation.

Material: Commonly made from bronze, stainless steel (316/316L), or composite polymers (e.g., Noryl, EPDM).

Operating Temperature: -20°F to 250°F (-29°C to 121°C), varies by material.

Pressure Rating: 50 to 150 PSI, depending on design and seal type.

Corrosion Resistance: High resistance to saltwater, chemicals, and abrasion.

Impeller Type: Open, semi-open, or closed design based on fluid handling needs.

Shaft Compatibility: Matches standard marine pump shafts (e.g., 1/2" to 1-1/2" diameter).
