Cargo pump mechanical seals in marine pumps are critical components designed to prevent fluid leakage in harsh marine environments. They ensure reliable operation by maintaining a tight seal between rotating and stationary parts. These seals are built to withstand high pressures, corrosive fluids, and extreme temperatures.

Size: 25 mm to 200 mm (shaft diameter)

Grade: API 682, ISO 21049 compliant

Viscosity Range: 1 cSt to 1000 cSt

Buoyancy: Not applicable (mechanical seals are static components)

Material: Carbon, Silicon Carbide, Tungsten Carbide, Stainless Steel (AISI 316), EPDM, Viton

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

Temperature Range: -20°C to +200°C (varies by seal material)

Speed: Up to 3600 RPM

Seal Type: Single, double, or tandem configurations

Fluid Compatibility: Crude oil, diesel, lube oil, chemicals, seawater

Marine Pump Type: Centrifugal, screw, or gear pumps (common in marine applications)

Standards: ABS, DNV, LR, BV certified for marine use

Face Lubrication: Balanced or unbalanced designs

Cargo Pump Mechanical Seals and Marine Pumps typically comply with maritime standards such as ISO 21049 (API 682), ISO 5199, and ABS, DNV, or other classification society requirements.
