B&G RPU-160 Reversible Hydraulic Autopilot Pump

B&G / Simrad RPU-160 Reversible Hydraulic Autopilot Pump (21118203)

The B&G / Simrad RPU-160 (Part Number: 21118203 / 000-13766-001) is a heavy-duty 12V DC Reversible Hydraulic Steering Drive Pump engineered for medium-to-large vessel autopilot systems. Designed to drive hydraulic steering cylinders with displacements ranging from 160 cm³ to 550 cm³ (9.8 to 33.5 cu. in.), it delivers steady, low-noise hydraulic flow to maintain precise rudder and heading control.

Operating in conjunction with high-current autopilot computers (such as the B&G / Simrad AC42, NAC-3, or H5000 Pilot Computer), the RPU-160 adjusts hydraulic fluid direction and flow rate depending on polarity and drive signals. Built with marine-grade cast alloy housing and internal check valves to eliminate rudder feedback, it ensures minimal steering lag and reliable operation in harsh open-ocean conditions.

Key Features

• Reversible DC Hydraulic Drive: Reverses motor rotation direction to push hydraulic fluid, controlling port/starboard cylinder actuation.

• Wide Cylinder Volume Capacity: Supports steering cylinder displacements from 160 cm³ to 550 cm³.

• Integral Check Valves: Built-in lock valves isolate manual helm steering from autopilot hydraulic feedback pressures.

• High-Current Pilot Computer Compatibility: Direct drive interface with AC42, NAC-3, and H5000 marine autopilot computer modules.

• Rugged Marine Design: Sealed motor housing and corrosion-resistant body withstand engine room moisture and temperature extremes.
