Sae J1171 Marine Hydraulic Fluid is a specialized fluid designed for marine applications, offering corrosion resistance and stability in harsh environments.

Marine pumps are engineered to handle this fluid, ensuring efficient and reliable operation in marine hydraulic systems.

Both are critical for maintaining performance and longevity in marine machinery and equipment.

SAE J1171 Marine Hydraulic Fluid:

- Viscosity Grade: ISO 32, 46, 68 (common grades)

- Kinematic Viscosity: 32 cSt at 40°C (ISO 32), 46 cSt at 40°C (ISO 46), 68 cSt at 40°C (ISO 68)

- Buoyancy: Non-buoyant (sinks in water)

- Material: Mineral oil-based or synthetic formulations

- Fire Resistance: Not inherently fire-resistant (standard hydraulic fluid)

- Compatibility: Suitable for marine hydraulic systems with seals and hoses

Marine Hydraulic Pumps (SAE J1171 compliant):

- Size Range: Varies (common displacements: 5 cc/rev to 500 cc/rev)

- Pressure Rating: Typically 1500-3000 psi (varies by model)

- Material: Cast iron, steel, or bronze housings

- Seal Material: Nitrile, polyurethane, or fluorocarbon

- Viscosity Range: Compatible with ISO 32-68 fluids

- Buoyancy: Depends on housing material (generally non-buoyant)

- Mounting: SAE flange or direct coupling options
