Hydraulic Power Units (HPUs) in marine applications provide pressurized fluid to operate hydraulic systems on ships and offshore platforms. Marine hydraulics ensure reliable performance for steering, winches, cranes, and other heavy-duty equipment. These units are designed to withstand harsh marine environments, including corrosion and high humidity.

Key specifications and technical properties of Marine Hydraulic Power Units:

Size: Compact to large, typically ranging from 20L to 500L reservoir capacity.

Grade: Marine-grade hydraulic oil (ISO VG 32, 46, or 68).

Viscosity: 30-150 cSt (depending on operating temperature).

Buoyancy: Not applicable (stationary or mounted systems).

Material: Corrosion-resistant (stainless steel, aluminum, or coated carbon steel).

Pressure Range: 150-350 bar (standard marine applications).

Flow Rate: 5-100 L/min (varies by system requirements).

Temperature Range: -20°C to 80°C (operating).

Filtration: 10-25 micron (high-efficiency particulate filtration).

Cooling: Air or water-cooled (depending on application).

Certification: DNV, ABS, or other marine classification standards.

Yes, Hydraulic Power Units and Marine Hydraulics typically comply with maritime standards such as ISO 4413, DNV, ABS, and Lloyd's Register standards.
