Furuno Autopilot Pump Product Description
Discover Seamless Steering with the Furuno PUMPHRP17-12 Autopilot Pump
Imagine gliding across open waters with autopilot precision that feels almost intuitive. The Furuno PUMPHRP17-12 reversing pumpset brings that reality to your vessel, perfectly syncing with NavPilot series autopilots to handle hydraulic steering systems effortlessly. Whether you're chasing horizons on a mid-sized cruiser or managing demanding offshore runs, this 12VDC pump delivers 1.7 cubic inches per second of flow—ideal for rams between 14 and 25 cubic inches. It's not just about performance; it's about quiet confidence on every voyage.
Engineered for Whisper-Quiet Reliability
At the heart of the PUMPHRP17-12 lies a reversible gerotor gear pump: a smart two-piece gear setup nestled in an eccentric ring. This design minimizes noise and vibration, ensuring your cockpit stays serene even during high-demand maneuvers. Boat owners rave about its durability—built to withstand the rigors of saltwater exposure and constant cycling without skipping a beat.
- Precise Flow Control: Outputs a steady 1.6-1.7 cu. in./sec, matching your ram size for responsive turns.
- Reversible Operation: Seamlessly shifts direction for port or starboard steering.
- Compact and Robust: Easy integration without bulky modifications.
Understanding Hydraulic Steering: How the Pump Fits In
Hydraulic steering transforms wheel turns into rudder action through fluid dynamics. Your helm pump pushes oil into the cylinder's port or starboard side, displacing the piston connected to the tiller arm and rudder post. The PUMPHRP17-12 steps in as the autopilot's muscle, mimicking these movements electronically for hands-free control.
Pro Tip: In multi-station setups, link helm pumps with a return/fill line to balance pressure and prevent cavitation. This pump thrives in such configurations, maintaining system efficiency across all stations.
Perfect Match for Your Vessel's Needs
Designed for boats with hydraulic rams in the 14-25 cubic inch range, this pump pairs flawlessly with Furuno's NavPilot 400/600/700 series. It's a go-to upgrade for sailors tired of sluggish manual steering or unreliable retrofits. Real-world users report faster response times and reduced pilot fatigue on long passages.
Compatibility extends to most standard hydraulic actuators—verify your ram volume first for optimal performance. No need for oversized pumps that waste power; this one's Goldilocks flow keeps your 12V system efficient.
Why Boaters Choose the PUMPHRP17-12 Over Alternatives
It's the trifecta of quiet operation, pinpoint accuracy, and long-term dependability. Unlike centrifugal pumps that whine under load, the gerotor tech here ensures smooth, vibration-free steering. Skip the guesswork of DIY hydraulics—this Furuno pump installs with minimal plumbing tweaks, saving hours of frustration.
"Switched to the HRP17-12 last season—night and day difference in autopilot smoothness. No more clunks or hesitation." – Experienced Offshore Skipper
Plus, its precise metering reduces wear on seals and hoses, extending your entire steering system's life.
Installation Essentials for Peak Performance
- Mount Securely: Choose a dry, accessible spot near the autopilot processor with good airflow.
- Plumb Properly: Connect high-pressure lines to port/starboard cylinder ports; use quality hoses rated for marine hydraulics.
- Wire Cleanly: Direct 12VDC feed with a 20A fuse—polarity matters for reversal.
- Bleed Thoroughly: Cycle the system multiple times to purge air, preventing spongy steering.
- Test Extensively: Dockside trials at various RPMs ensure sync with NavPilot sensors.
Common Pitfall: Undersized wiring leads to voltage drops—use at least 12-gauge for runs over 10 feet.
Maintenance Tips to Keep It Running Strong
Simplicity is key: Annual checks of oil levels, line fittings, and electrical connections go a long way. Flush the system every two years with marine-grade hydraulic fluid to fend off contamination. Monitor for leaks around the gerotor housing—early detection prevents bigger headaches.
Store spares like O-rings and filters onboard; they're inexpensive insurance against downtime.
Frequently Asked Questions
What ram sizes is the Furuno PUMPHRP17-12 compatible with?
It's optimized for hydraulic rams from 14 to 25 cubic inches, providing the right flow for responsive steering without overpowering smaller setups.
How does the gerotor pump design benefit my boat?
The two-piece gear in an eccentric ring delivers ultra-quiet, vibration-free operation with superior reliability, ideal for extended cruising.
Can I use this pump with multiple helm stations?
Yes, just install a return/fill line connecting all helm pumps to equalize pressure and ensure smooth autopilot integration.
What voltage does the PUMPHRP17-12 require?
It runs on a standard 12VDC marine electrical system, drawing efficiently to match your onboard power setup.
Is installation DIY-friendly for experienced boaters?
Absolutely—basic plumbing and wiring skills suffice, but always bleed the system fully and test before heading out.
How do I troubleshoot slow steering response?
Check for air in lines, low fluid, or voltage issues first. Recalibrating the NavPilot often resolves sensor mismatches.
What's the expected lifespan of this pump?
With proper maintenance, it easily lasts 5-10 years or more in typical marine environments, thanks to its robust gerotor construction.
Autopilot Pump, 12 VDC, 1.7 Cubic Inches Per Second (For Ram Sizes of 14 Cubic Inches to 25 Cubic Inches in Volume)
The PUMPHRP17-12 is a reversing pumpset designed to interface the NavPilot series autopilot with a hydraulic steering system. The pump assembly incorporates a reversible gerotor gear pump, a two-piece gear housed in an eccentric ring. This allows for incredibly quiet, reliable and precise operation.
A hydraulic steering system consists of a hydraulic actuator and one or more steering wheel pumps, or helm pumps. As the steering wheel (helm pump) is turned in the port direction, hydraulic oil is pumped into the port hydraulic steering line. This oil is directed into the port side of the steering cylinder. As the cylinder moves to port, oil from the starboard side of the cylinder returns to the helm pump through the starboard hydraulic lines.
One end of the cylinder is fixed and the other is connected to a tiller arm, which is connected to a rudder shaft. With this connection to the tiller arm the linear movement of the cylinder to port is changed to rotary movement, which turns the rudder and steers the vessel to port. Moving the steering wheel to starboard produces the same reaction with oil being pumped out of the starboard line and returning through the port line.
If more than one helm pump is used, a return/fill line must be installed to connect the cases of all helm pumps together.
The output flow rate of the pumpset determines the speed of the steering cylinder. The PUMPHRP17-12 outputs 1.6 cu. in. of oil per second and requires a 12VDC input.
