Cargo Pump Seal Springs in marine pumps ensure proper sealing by maintaining consistent pressure on the seal faces. They are designed to withstand harsh marine environments, including corrosion and high pressures. These springs enhance pump reliability and prevent leaks in critical cargo transfer operations.

Size: Typically ranges from 0.5 mm to 10 mm in diameter, depending on pump model.

Grade: ASTM A313 (stainless steel), ASTM B159 (phosphor bronze), or equivalent marine-grade materials.

Viscosity: Not applicable (springs are mechanical components, not fluids).

Buoyancy: Negligible (metallic springs are non-buoyant in water).

Material: 316 stainless steel, Inconel X-750, or phosphor bronze for corrosion resistance.

Operating Temperature: -50°C to 250°C, depending on material.

Pressure Rating: Compatible with pump pressures up to 40 bar (580 psi).

Spring Rate: 5 N/mm to 200 N/mm, tailored to seal load requirements.

Corrosion Resistance: Marine-grade coatings or passivation for saltwater environments.

Compliance: Meets ISO 10438, API 682, and marine classification standards (e.g., ABS, DNV).

Cargo Pump Seal Springs and Marine Pumps typically comply with maritime standards such as ISO 21049 (API 682), ASTM F1511, and other industry-specific regulations. For exact compliance, refer to the manufacturer's specifications or certification documents.
