Size: Typically ranges from 10 cc/rev to 500 cc/rev depending on vessel size and steering gear requirements.
Grade: Hydraulic fluid grades such as ISO VG 32, ISO VG 46, or MIL-PRF-17672D for marine applications.
Viscosity: Operates within 15-160 cSt, with optimal performance at 30-50 cSt depending on temperature.
Buoyancy: Not applicable as pumps are installed within the vessel's hull or machinery spaces.
Material: Cast iron, bronze, or stainless steel for corrosion resistance in marine environments.
Pressure Rating: 150-300 bar, with some high-pressure systems reaching 350 bar.
Flow Rate: 5-200 L/min, adjustable based on steering gear demand.
Temperature Range: -20°C to +80°C for standard operation, with optional heating/cooling for extreme conditions.
Drive Type: Electric motor or hydraulic drive, with power ranging from 1 kW to 50 kW.
Seals: Nitrile (NBR), Viton (FKM), or PTFE for compatibility with hydraulic oils and seawater resistance.
Mounting: Foot-mounted or flange-mounted configurations for integration with steering systems.
Compliance: Meets IMO, SOLAS, and Class Society standards (e.g., ABS, DNV, LR).
