Bilge Pump Diaphragm Retainers are essential components in marine pumps, securing the diaphragm in place for efficient operation. They ensure proper sealing and prevent leaks during bilge water removal. Made from durable materials, they withstand harsh marine environments for long-lasting performance.

Size: Typically ranges from 1/2 inch to 2 inches in diameter, depending on pump model.

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

Viscosity: N/A (not applicable for solid components like retainers).

Buoyancy: Neutral buoyancy; designed to withstand submersion without floating.

Material: Stainless steel (316/316L), brass, or high-performance polymers (e.g., PTFE, Nylon).

Operating Temperature: -20°C to 120°C (-4°F to 248°F), varies by material.

Pressure Rating: 50-150 PSI, depending on design and application.

Corrosion Resistance: High; resistant to saltwater, oils, and chemicals.

Compatibility: Suitable for use with diesel, gasoline, and bilge water.

Finish: Polished or coated for enhanced durability.

Bilge Pump Diaphragm Retainers and Marine Pumps typically comply with maritime standards such as ISO 8846, ABYC H-22, and USCG regulations. Always verify with the manufacturer for specific compliance details.
