STAFFA HYDRAULIC POWER UNIT (HPU) FOR MARINE APPLICATIONS

Staffa Hydraulic Power Units (HPU) are widely used in marine and offshore hydraulic systems where reliable hydraulic pressure and flow are required to operate heavy-duty deck machinery. These HPUs are commonly integrated with Staffa hydraulic motors, winches, windlasses, deck cranes, and hatch cover systems.

The hydraulic power unit serves as the heart of the hydraulic system by supplying pressurized hydraulic oil to motors, cylinders, and valve blocks installed throughout the vessel.

SM MARINE SERVICE™ supplies both New Equipment and Reconditioned Equipment for various marine hydraulic applications.

WHAT IS A STAFFA HYDRAULIC POWER UNIT?

A Staffa Hydraulic Power Unit is a complete hydraulic power generation package consisting of:

• Hydraulic Pumps
• Electric Motors
• Hydraulic Reservoir Tank
• Filtration System
• Pressure Relief Valves
• Directional Control Valves
• Accumulators
• Cooling System
• Instrumentation
• Electrical Control Panel

The HPU generates hydraulic pressure and distributes hydraulic energy to various deck machinery systems installed onboard ships and offshore platforms.

MAIN MARINE APPLICATIONS

Marine HPU

General hydraulic power supply for vessel hydraulic systems including deck machinery, steering systems, cranes, and cargo handling equipment.

Mooring HPU

Provides hydraulic pressure to Staffa hydraulic motors used in mooring winches for safe vessel mooring operations.

Windlass HPU

Operates anchor windlass systems and supplies power for anchor handling operations.

Crane HPU

Used in electro-hydraulic deck cranes, offshore cranes, and cargo handling cranes.

Hatch Cover HPU

Provides hydraulic pressure for opening and closing hydraulic hatch covers on bulk carriers and cargo vessels.

SM MARINE SERVICE™ supports marine hydraulic system repairs, troubleshooting, and spare parts sourcing worldwide.
