Cargo Pump Seal Rings in marine pumps are critical components designed to prevent leakage and ensure efficient fluid transfer. They provide a tight seal between rotating and stationary parts, enhancing pump reliability and safety. Made from durable materials, they withstand harsh marine environments and corrosive fluids.

Size: 50 mm to 500 mm (varies by pump model)

Grade: ASTM D2000, ISO 3601, or equivalent marine standards

Viscosity: Compatible with fluids ranging from 10 cSt to 1000 cSt

Buoyancy: Neutral to slightly positive in seawater (1.02-1.05 g/cm³)

Material: Nitrile rubber (NBR), Viton (FKM), or PTFE (for high-chemical resistance)

Pressure Rating: 10 bar to 40 bar (depending on design)

Temperature Range: -20°C to +150°C (varies by material)

Hardness: 70-90 Shore A (for elastomers)

Chemical Resistance: Fuel, oil, seawater, and mild acids/alkalis

Seal Type: Mechanical seal or lip seal (application-specific)

Standards Compliance: ABS, DNV, LR, or other marine classification societies

Cargo Pump Seal Rings and Marine Pumps typically comply with maritime standards such as ISO 5199, API 610, and ABS (American Bureau of Shipping) requirements. Always verify with the manufacturer for specific certifications.
