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.

The Furuno PUMPHRP17-12 is a reliable 12 VDC reversing hydraulic pump designed for seamless integration with NavPilot series autopilots and hydraulic steering systems. This pump features a gerotor gear mechanism housed in an eccentric ring, ensuring quiet operation, precise control, and consistent performance. Ideal for vessels with ram sizes ranging from 14 to 25 cubic inches, it delivers a flow rate of approximately 1.6 cubic inches per second, enabling smooth and responsive steering adjustments. The durable construction and efficient design make it suitable for demanding marine environments, providing peace of mind during navigation.
This hydraulic pump operates by directing hydraulic oil into the steering cylinder, converting linear movement into rotary motion to turn the vessel’s rudder. When the helm is turned port or starboard, the pump ensures balanced oil flow to the corresponding sides of the cylinder, facilitating accurate vessel control. It is compatible with systems employing multiple helm pumps, with a return/fill line necessary to connect pump cases, ensuring proper hydraulic circulation. The compact size and straightforward installation make it an excellent choice for integrating into existing hydraulic steering setups.
The Furuno PUMPHRP17-12 is engineered for dependable performance and quiet operation, making it suitable for both new installations and replacements. It is designed to interface seamlessly with Furuno's autopilot systems, enhancing vessel handling and navigation precision. For detailed installation instructions and maintenance guidelines, refer to the owner’s manual available online. Note that this product may require professional installation and should be handled according to safety standards. As with all hydraulic components, proper maintenance and cautious handling are essential to ensure longevity and optimal performance.
