Hy-ProDrive PR+20 RU Reversing Pump 12V (PR20-12-RU)
2.0 L/min Pump 12VDC 100W with Reservoir and Unloader
PR+ RU Reversing DC Hydraulic Power Unit with reservoir and clutch
Reversing type gear pumps driven by 12 or 24 volt DC permanent magnet motors. Incorporated in the design are pilot operated check valves that prevent the pump being back driven by the manual steering system or rudder load.
The motors have an IP67 rating and can be removed from the pump without allowing air into the hydraulic system or fluid to escape. They can be used with both balanced and unbalancedcylinders. The pumps incorporate a fluid reservoir plus an unloading solenoid to allow the steering cylinder to ‘float’ when not in autopilot mode.
When used in conjunction with a cylinder of your choice it forms a linear actuator to enable secondary steering via an autopilot.
