HYDRAULIC POWER STEERING

The size of the cylinder is determined according to
the rudder torque.

Hydraulic pump type HT1029
Although the engine manufacturer will often supply the hydraulic pump,
VETUS can also offer a fixed volume hydraulic pump, which is belt driven off
the main engine. 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).

• Maximum shaft speed: 3,500 rpm
• Suction and pressure connections are included.
If an existing engine driven pump is to be used, the hydraulic flow rate must be minimum 1.8 gal./min (7 l/min) and
maximum 10.5 gal./min (40 l/min), with a maximum working pressure of 1015 psi.

POWER STEERING STAND ALONE SYSTEM WITH SMALL GEAR PUMP
AND SMALL HYDRAULIC TANK
3 Possibilities
1. A boat equipped with a VETUS hydraulic
installation (a hydraulic power steering
system can always be added)
2. A boat equipped with a hydraulic
installation not supplied by VETUS (it is
always possible to add a hydraulic power
steering system with a custom made
modification, please consult VETUS).
3. A boat without a hydraulic installation;
use a stand-alone system.
