PR+ RU Reversing DC Hydraulic Power Unit with reservoir and clutch.  Reversing type gear pumps driven by 12V/24V 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 unbalanced cylinders.
 
Description
 
The PR+RU incorporates the proven PR+ reversing pump and motor range but with an integral reservoir and solenoid unloader valve.
 
Complete with pilot check valves this compact unit can be used where the vessel has a mechanical primary steering and an autopilot stand-alone secondary hydraulic drive is required. With just two hose connections, uniquely the unit can be used with balanced or unbalanced cylinders*. The unloader solenoid coil is switched by the course computer clutch connection to engage and disengage the drive.
 
By design the very low back drive loads preserve the feel of the helm when steering by hand. The reservoir allows for extreme heel angles without any fluid loss and the IP67 motor and solenoid ensure no water ingress problems.
 
In the event of primary mechanical steering failure the system can be used as emergency steering with the autopilot.
 
Manufactured from corrosion resistant marine grade materials the unit can be easily serviced and the motor changed with just two bolts and no fluid loss or air ingress into the system.
 
With the option of omitting the unloader valve the unit can be used in other hydraulic applications such as hatch, window and bathing platforms with the check valves locking the hydraulic cylinder in place.
 
 *maximum differential volume 50 cc.
 
Application
 
When connected to a secondary steering cylinder it forms a compact linear drive.
