Power Assist Hydraulic Steering Pump

The Dometic SeaStar Power Assist PA1200-3 is an electronically controlled gear pump integrated into the hydraulic steering system between the helm and steering cylinder. It enhances steering by directing fluid from the helm pump through the gear pump to the steering cylinder(s). The helm controls both speed and direction, while the power assist functions as the active component that amplifies steering force. The gear pump’s speed is proportional to the helm’s movement—turning the wheel faster increases pump speed. When not in use, the power assist remains idle, drawing only standby power.

SeaStar Power Assist Update:
Dometic Marine is pleased to announce that we have updated our very popular SeaStar Power Assist product and have eliminated redundant models.  The new -3 series of SeaStar Power Assist pumps have undergone a performance improvement with new electronics and the addition of ORB fittings similar to steering helms and cylinders.
