Bilge pump motor brushes are essential components that conduct electrical current to the motor's rotating armature. These brushes ensure reliable operation of marine pumps by maintaining consistent contact and power transfer. Made from durable materials, they withstand harsh marine environments for long-lasting performance.

Size: Typically 10-30 mm in length, 5-15 mm in width, and 5-10 mm in thickness.

Grade: High-performance carbon or graphite-based materials, often with copper or silver additives for enhanced conductivity.

Viscosity: Not applicable (N/A) for solid brushes; lubricants used may have viscosities of 10-50 cSt.

Buoyancy: N/A (solid components; buoyancy is not a relevant property).

Material: Carbon-graphite composites, often with metal impregnation (e.g., copper, silver) for marine-grade durability.

Current Rating: 10-50 A depending on motor size and application.

Voltage Rating: 12-24 V DC for most marine bilge pump systems.

Operating Temperature: -20°C to +120°C for standard marine environments.

Water Resistance: IP67 or higher for submersion and saltwater exposure.

Lifespan: 500-2000 hours of continuous operation, depending on load and conditions.

Bilge Pump Motor Brushes and Marine Pumps typically comply with maritime standards such as ABYC (American Boat and Yacht Council), USCG (U.S. Coast Guard), and ISO 8846 for marine electrical systems. Always verify specific product certifications with the manufacturer.
