PC45 Constant Running Power Unit

The versatile PC45 constant running power unit uses a heavy-duty 4 brush fan cooled motor to deliver 4.5 lpm. For use in heavy duty applications on larger yachts or commercial craft these units come fitted with pressure compensated flow controls, relief valves and cylinder lock valves as standard. Developed specifically for marine autopilot applications in the commercial and larger pleasure boat market the PC45 can be used with single or twin ram systems.

The unit is designed to be compatible with both balanced and unbalanced rams and pressurised reservoir type systems.
