Marine steering gear pumps are hydraulic systems that control the direction of a vessel by transmitting fluid pressure to the steering mechanism. These pumps ensure precise and reliable rudder movement, essential for safe navigation. They are designed to withstand harsh marine conditions and provide consistent performance under varying loads.

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).
