Simrad Steady Steer Flow Switch for Older RPU Series Pumps.

The Simrad Steady Steer Flow Switch for Older RPU Series Pumps is a precision marine steering component engineered for legacy hydraulic autopilot systems operating in commercial and recreational vessel environments. This replacement flow switch addresses the growing need for reliable parts availability as older Simrad pump assemblies remain in active service across fishing fleets, research vessels, and offshore operations. Built to restore full steering automation capability, this component ensures that legacy navigation systems continue performing at original specifications without costly vessel downtime.

The flow switch mechanism regulates hydraulic pressure feedback within the RPU pump assembly, maintaining precise steering response and preventing system overpressure conditions that compromise autopilot accuracy. This component integrates seamlessly with the pump's pressure-sensing circuit, translating fluid dynamics into electrical control signals that govern helm actuator positioning. Constructed from marine-grade materials resistant to saltwater corrosion and thermal cycling, the Simrad Steady Steer Flow Switch delivers the durability demanded by extended offshore operations and harsh coastal environments where steering system reliability directly impacts vessel safety and navigation precision.

Marine technicians and vessel operators managing aging Simrad autopilot installations will find this replacement switch essential for maintaining steering system redundancy and regulatory compliance. Installation requires basic knowledge of hydraulic line routing and electrical harness connectivity—well within the capability of experienced marine mechanics or certified Simrad service centers. Compatibility with older RPU series pumps makes this an economical alternative to complete system replacement, extending the operational lifespan of proven autopilot technology while preserving original equipment integration and performance characteristics across all vessel classes relying on Simrad steering automation.
