Simrad PUMP-5 24v Reversible Hydraulic Pump 17.7 - 58.5cui Replaces RPU300

Upgrade Your Vessel's Steering with Reliable Power

Navigating larger boats demands precise control, especially in rough seas or during long hauls. The Simrad PUMP-5 24V reversible hydraulic pump steps in as a robust solution, delivering smooth, responsive steering that keeps you confident at the helm. Designed for marine environments, this pump handles demanding conditions while replacing older RPU300 units, ensuring your autopilot system stays current and efficient.

Whether you're retrofitting an existing setup or building a new one, its high-flow design minimizes lag, providing instant response to rudder commands. Boat owners rave about the reduced effort needed for maneuvers, turning challenging docking situations into effortless operations.

Standout Features for Peak Performance

• Reversible Operation: Seamlessly switches direction for full port-to-starboard control, ideal for twin-rudder or outboard setups.
• High Flow Rate: Pumps up to 3.0 liters per minute, supporting cylinder displacements from 290 to 960 cc (17.7 to 58.5 cubic inches) for quick, powerful steering.
• 24V DC Power: Matches modern vessel electrical systems, drawing efficient power without draining batteries during extended use.
• Compact and Durable Build: Corrosion-resistant materials withstand saltwater exposure, vibrations, and constant pressure cycles.
• Quiet Efficiency: Gear-driven design reduces noise and heat buildup, enhancing onboard comfort.

These features aren't just specs—they translate to real-world reliability. Imagine crisp handling during high-speed cruises or precise adjustments in tight marinas, all without the hydraulic whine that plagues lesser pumps.

Perfect Fit for Your Autopilot System

This pump pairs seamlessly with NAC-3 and AC42 autopilot computers, creating a synchronized steering ecosystem. It's tailored for vessels up to 60 feet with hydraulic steering, from sportfishing yachts to commercial workboats. If your current RPU300 is showing wear—sluggish response, leaks, or inconsistent pressure—swapping it out restores factory-fresh performance.

Pro tip: Check your cylinder size first. The 290-960 cc range covers most mid-to-large setups, but matching it right avoids over- or under-pressurization, extending the life of your entire hydraulic circuit.

Effortless Installation and Long-Term Maintenance

Installation mirrors standard hydraulic pumps: Mount securely, connect hoses with proper fittings, wire to your 24V supply, and integrate with your autopilot. Use quality hydraulic fluid like ATF to prevent cavitation. Most skippers complete the job in a weekend with basic tools—no need for a full yard overhaul.

For maintenance, inspect seals annually and top off fluid as needed. The reversible design simplifies troubleshooting—run it in reverse to flush debris. With proper care, expect years of trouble-free service, outlasting competitors in harsh marine conditions.

"Switched from an old RPU300, and the difference is night and day. Steering feels alive again." – Experienced offshore captain

Real-World Applications and Benefits

Fishermen appreciate the pump's torque for fighting currents, while cruisers value the stability on autopilot during overnight passages. It's a game-changer for vessels with multiple steering stations, ensuring consistent pressure across rams.

Compared to fixed-direction pumps, the reversible action eliminates manual overrides, boosting safety and reducing crew fatigue. Energy-wise, its efficient flow means less load on generators, perfect for eco-conscious operators.
