Grade: Marine-grade materials, often certified for saltwater use.

Viscosity: Handles fluids up to 1,000 cP (centipoise) depending on the model.

Buoyancy: N/A (pumps are fixed installations).

Material: Stainless steel, bronze, or reinforced thermoplastics for corrosion resistance.

Power: 12V, 24V, or 110V/220V AC, depending on the application.

Flow Rate: 10-50 gallons per minute (GPM) for standard marine macerator pumps.

Pressure: Operates at low to moderate pressure (10-30 PSI).

Impeller Type: Cutting or grinding blades for macerator pumps, non-clog designs for standard marine pumps.

Temperature Range: -10°C to 60°C (14°F to 140°F) for most models.

Certifications: Often meets ABYC, USCG, or ISO standards for marine use.
