Cargo pump shafts in marine pumps are critical components designed to transfer power from the motor to the impeller, ensuring efficient fluid movement. They are typically made of durable materials like stainless steel to withstand harsh marine environments. Proper alignment and maintenance are essential to prevent wear and ensure reliable operation.

Cargo Pump Shafts and Marine Pumps Key Specifications:

Size: Typically range from 50mm to 300mm in diameter, lengths vary based on vessel requirements.

Grade: Commonly ASTM A479, A564, or AISI 316/316L for corrosion resistance.

Viscosity: Designed to handle fluids with viscosities up to 1,000 cSt (centistokes).

Buoyancy: Neutral or slightly positive buoyancy depending on material and design.

Material: Stainless steel (316/316L), duplex steel (2205), or super duplex (2507) for seawater resistance.

Pressure Rating: Typically 10-40 bar, depending on pump type and application.

Temperature Range: -20°C to +150°C, with higher grades accommodating extreme conditions.

Corrosion Resistance: High, with coatings or anodizing for harsh marine environments.

Load Capacity: Axial and radial loads vary by design, often rated for 5-20 kN.

Connection Type: Flanged, threaded, or welded based on system requirements.

Cargo Pump Shafts and Marine Pumps typically comply with maritime standards such as ISO 15749, ISO 5199, and ABS, DNV, or other classification society requirements. For specific compliance, refer to the manufacturer's documentation or certification details.
