Bilge Pump Diaphragms are flexible components in marine pumps that move fluids by expanding and contracting. They are essential for efficient bilge water removal, ensuring vessel safety. Made from durable materials, they resist corrosion and wear in harsh marine environments.

Size: Typically ranges from 1.5" to 3" in diameter, depending on pump model.

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

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

Buoyancy: Neutral buoyancy to prevent sinking or floating in bilge water.

Material: Nitrile rubber (NBR), EPDM, or Viton for chemical and oil resistance.

Operating Temperature: -20°C to +80°C (-4°F to +176°F).

Pressure Rating: Withstands up to 50 PSI (3.4 bar).

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

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

Compatibility: Fits major marine pump brands like Jabsco, Rule, and Whale.

Bilge Pump Diaphragms and Marine Pumps typically comply with maritime standards such as ISO 8846, ABYC H-22, and USCG regulations. Always verify specific product certifications with the manufacturer.
