The Boat Motor Water Pump Impeller is a crucial component in marine engines, responsible for circulating cooling water to prevent overheating. Marine pumps ensure efficient water flow, maintaining optimal engine performance and longevity. These impellers are typically made of durable rubber or composite materials to withstand harsh marine conditions.

The Boat Motor Water Pump Impeller and Marine Pumps typically have the following key specifications and technical properties:

Size: Varies by model (common sizes range from 30mm to 60mm in diameter).

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

Viscosity: Designed for low-viscosity fluids (water, coolant).

Buoyancy: Neutral buoyancy in water (material-dependent).

Material: Nitrile rubber (NBR), neoprene, or EPDM for impellers; stainless steel or bronze for pump housings.

Operating Temperature: -20°C to 120°C (varies by material).

Pressure Rating: Typically 10-50 PSI (depends on pump design).

Flow Rate: 5-50 GPM (varies by pump size and motor RPM).

Compatibility: Saltwater or freshwater use (material-specific).

Lifespan: 1-5 years (depends on usage and maintenance).
