Steering gear pumps in marine propulsion systems provide hydraulic power to control the ship's rudder, ensuring precise maneuverability. These pumps are typically electrically or mechanically driven, delivering high-pressure fluid to the steering mechanism. They are critical for safe navigation and operational efficiency of vessels.

Size: Typically ranges from 10 cc/rev to 250 cc/rev depending on application.

Grade: Hydraulic fluid grades such as ISO VG 32, 46, or 68 are commonly used.

Viscosity: Operates within 15-160 cSt, with optimal performance at 30-50 cSt.

Buoyancy: Not applicable as these are fixed or mounted components.

Material: Housing is usually cast iron or aluminum; internal components are steel or bronze.

Pressure Rating: 150-250 bar (2175-3625 psi) for standard models.

Flow Rate: 5-100 L/min (1.3-26.4 GPM) depending on pump size.

Temperature Range: -20°C to 80°C (-4°F to 176°F) for standard operation.

Rotation: Clockwise or counterclockwise, depending on design.

Mounting: Flange or foot-mounted configurations.

Seals: Nitrile or Viton for compatibility with hydraulic fluids.

Efficiency: 85-92% volumetric efficiency for high-performance models.

Noise Level: Typically below 75 dB at 1 meter distance.

Weight: 5-50 kg (11-110 lbs) based on size and material.

Yes, Steering Gear Pumps and Marine Propulsion systems typically comply with international maritime standards such as ISO, SOLAS, and IMO regulations.
