SR Series rotary vane steering gear
The design gives smooth starting and stopping of the steering gear, and enables a precise analogue control system.
Unique technical solutions minimise noise and vibration levels
The SR series is suitable for small to medium-sized vessels. The steering gear is designed with integrated frequency controlled pumps. The pump utilises a reversible hydraulic pump motor together with a frequency converter to reduce the power consumption and to change the speed and the direction of the pump. The design gives smooth starting and stopping of the steering gear, and enables a precise analogue control system. The pump units are mounted directly on the rudder actuator, which lessens the need for piping work on board a vessel. Full frequency control means the pumps and motors are only running when a steering command is given, this reduces the amount of heat generated and leads to cleaner hydraulic system, improving the lifetime of components.
