Simrad RPU300 24v Pump
Simrad RPU300 24v Pump — Product description
Upgrade your vessel's steering with the powerhouse performance of the Simrad RPU300 24V pump, a reversible hydraulic drive unit engineered for seamless autopilot operation on boats reaching up to 70 feet. This isn't just another pump—it's the reliable backbone for maintaining precise course-keeping in demanding marine environments, from coastal cruises to offshore adventures. Boaters trust it for its robust build and consistent delivery of hydraulic power, ensuring your autopilot system responds instantly to helm commands without the lag that can compromise safety.
What sets this 24V version apart? It matches the impressive flow rate of its standard counterparts at 183 cubic inches per minute, but optimized for systems running on higher voltage setups common in larger yachts and commercial craft. Whether you're dodging choppy waves or holding a steady heading during long passages, this pump delivers the muscle needed for cylinder displacements between 290 and 960 cubic centimeters.
Core Features That Drive Superior Performance
- Reversible Design: Effortlessly switches direction for port and starboard steering, mimicking natural hydraulic flow without mechanical hesitation.
- High Flow Capacity: Pumps out 183 cui/min to handle substantial rudder loads, ideal for vessels with heavy displacement or high-speed plans.
- 24V DC Operation: Draws from 24 or 32V systems for efficient power use, reducing strain on batteries during extended voyages.
- Compact Yet Mighty: Built tough with marine-grade materials to resist corrosion from saltwater exposure, vibration, and extreme temperatures.
These features translate to real-world reliability. Imagine navigating through fog or night conditions where your autopilot needs to correct for crosswinds or currents— this pump ensures split-second hydraulic response, keeping you on track.
Seamless Integration into Your Autopilot Ecosystem
The RPU300 thrives as part of a complete Simrad autopilot setup, pairing perfectly with the NAC-3 or AC42 autopilot computers. These brains of the system calculate rudder angles and send precise signals to the pump, creating a closed-loop feedback that's responsive to boat dynamics like heel angle or speed changes.
Installation is straightforward for skilled installers: connect to your hydraulic ram, wire into the DC supply, and calibrate via the autopilot interface. No need for complex programming— the pump's reversible motor syncs automatically, minimizing setup time. It's compatible with a range of steering cylinders, making it versatile for retrofits on older boats or new builds.
Pro Tip for Optimal Setup
Position the pump as low as possible in the bilge to aid fluid priming and reduce air ingress risks. Always bleed the system thoroughly post-install to avoid cavitation, which can erode performance over time.
Why Boaters Rely on This Pump for Tough Conditions
In practical use, the RPU300 shines where others falter. Its high flow rate tackles the torque demands of larger rudders, preventing the "soft steering" feel that plagues underpowered units in beam seas. The 24V configuration supports beefier electrical systems without overheating, a common issue on extended runs with accessories like radars or thrusters drawing power.
Durability is key: sealed internals fend off moisture, while the motor's brushless-like efficiency cuts wear. Owners report thousands of hours of service with basic maintenance—check fluid levels seasonally and inspect hoses for cracks. Compared to pneumatic alternatives, hydraulic pumps like this one offer smoother operation and better holding power under load.
"On my 55-foot trawler, this pump transformed autopilot reliability. No more manual corrections in rough Gulf Stream waters." – Experienced skipper feedback echoed across forums.
Maintenance Essentials for Longevity
Keep it performing like new with simple routines:
- Monitor hydraulic fluid for contamination; use Simrad-approved ATF or equivalents.
- Inspect electrical connections for corrosion—marine environments accelerate this.
- Test reversal function quarterly to ensure solenoid health.
- Run diagnostics through the autopilot computer to catch issues early.
Neglect these, and you risk pump seizure or leaks. Proactive care extends life beyond a decade, making it a smart investment for serious mariners.

Key Features Reversible Pump High Flow Rate 24V DC 290-960 cc Hydraulic steering systems are now being used in every category of vessel. In many respects hydraulic steering is preferable to mechanical steering. Hydraulic systems normally comprise of two main components, a steering wheel pump and steering cylinder(s). The steering wheel pump may be either a gear pump or a plunger pump. Which ever type is installed, steering is achieved by turning the steering wheel in either direction causing oil from the wheel pump to be supplied to the appropriate side of the cylinder. Oil is returned via the opposite side of the cylinder back to the pump."
