Hydraulic Power Steering

For larger boats, VETUS hydraulic power steering is a most comfortable and extremely safe steering system. The effort required at the helm is only about 10% of a non-powered steering system. In other words: the boat can be steered literally with one finger. Because of this, the steering wheel diameter can be considerably smaller than normal; a wheel diameter of just Ø 360 mm will usually suffice.

Hydraulic pump with bearing block, 11.3 cm³/rev

This pump can be used in conjunction with our hydraulic power steering.
This VETUS pump has a built in bearing block. Its dimensions are small and are comparable with those of the alternator. The pump has a power take-off of approximately 1 kW (1.5 hp).

• Dimensions (l x w x h): 220 x 90 x 112 mm
• Weight: 5 kg
• Shaft diameter: 22 mm
• Maximum shaft speed: 3,500 rpm
• Suction and pressure connections are included

Electro-hydraulic pumps (DC Powerpacks)

These DC Powerpacks can be used as an alternative for a main engine driven pump in an hydraulic power steering system.
DC Power Packs can also be used as an extra pump in an hydraulic system where a pump is already installed on the propulsion engine. For example, a deck hatch can then be opened or closed even when the main engine is not running.
Available for 12 Volt with a 500 W motor and for 24 Volt with an 1100 W motor

If a pump with a fixed swept volume, or a high capacity is installed, or if the ambient temperature is high, a lot of heat can be generated. In these cases, the installation of an oil cooler in the return line will be required.

Four different cooling water hose diameters are available:
• Ø 32 (HT301132)
• Ø 42 (HT301142)
• Ø 47 (HT301147)
• Ø 2’’ thread (HT3011MP)
