VETUS HPM4,56 HYDRAULIC PROPULSION 52 HP

VETUS HPM4,56 is a hydraulic propulsion system equipped with a 4-cylinder VETUS M4.56 engine capable of delivering a maximum mechanical power of 52 Hp.

The engines of the VETUS HPM4,56 are quiet, reliable and offer high power and torque ratios. The fuel line is self-purging, a nice convenience when replacing the fuel filter. The VETUS HPM4,56 propulsion system engine is equipped with a high-power marine alternator for fast battery charging.

Thanks to a rugged aluminum heat sink and a newly designed air filter, VETUS has managed to make its engines exceptionally quiet, giving you the pleasure of a peaceful boating excursion.  

A rotary hydraulic pump is installed on the engine of the VETUS HPM4,56, instead of the inverter. This pump draws fluid from a special reservoir and pushes it under pressure to the control valve. The valve determines the direction and volume of fluid to be sent to the motor, which can then turn left or right depending on the direction chosen.

The transmission (reduction) ratio of the propulsion is determined by the difference in displacement between the rotary pump and the hydraulic motor. The reduction ratio, from the number of revolutions at the axle to the number of revolutions at the propeller is 2:1 for the VETUS model HPM4,56.

The maximum power of the main motor must be 50 kW, so an axle with a diameter of 25 mm will be sufficient. The VETUS HPM4,56 hydraulic motor flange is suitable for all types of flexible couplings.

The flange of the VETUS HPM4,56 hydraulic motor is suitable for all types of flexible couplings.
