PUMP-3 12V 1.6L Pump

The Navico PUMP-3 pump is a reversible gear hydraulic pump designed for use in marine autopilot systems. It is an integral part of the hydraulic steering system to help maintain the boat's heading.

The Navico PUMP-3 pump operates on a 12V DC power supply.

The Navico PUMP-3 pump has a nominal flow rate of 1.6 litres per minute (Lpm), which is equivalent to 98 cubic inches per minute (cu.in/min).

The Navico PUMP-3 pump weighs 2.6 kg.

The overall length (OAL) of the Navico PUMP-3 pump (model 000-15445-002) is 194 mm.

The Navico PUMP-3 pump uses O-Ring Boss (ORB) type connections.

The Navico PUMP-3 pump comes with three ORB-5 to 9/16 UNF fittings for easy hydraulic connections.

The typical current draw of the Navico PUMP-3 pump is 8 to 14 amperes. Peak current can reach 22 amperes at 50 bar pressure.

For installations in North America, the recommended tube material is 3/8" OD annealed copper (Type L ASTM B88) with a minimum wall thickness of 0.030".

Yes, the Navico PUMP-3 is a reversible hydraulic gear pump.

The model number and SKU reference for this pump are 000-15445-002.

Yes, the Navico PUMP-3 pump is the successor to the RPU160 model.

The PUMP-3 pump is designed for hydraulic steering cylinders with a displacement between 160 and 550 cubic centimeters (9.8 to 33.5 cubic inches).

For full integration and optimal operation, the PUMP-3 pump requires a Navico NAC-3 or AC42 autopilot computer.

Yes, the Navico PUMP-3 pump is compatible with Navico's SteadySteer system.

The Navico PUMP-3 pump is recommended for boats up to 15 meters (50 feet) in length.

For optimal performance, a minimum AWG 10 (6.0 mm²) wiring section is recommended for installing the PUMP-3 pump. It is important not to use undersized cables.

If the pump motor is not running, the first step is to check the voltage supplied to the motor using a voltmeter to ensure it is receiving the necessary power.

If the pump motor runs but the rudder does not move, this usually indicates that the system is not filled with oil. The oil level must then be topped up and the hydraulic system bled.

For optimal hard-over to hard-over (HO to HO) rudder movement time, it is crucial to ensure the pump is correctly sized relative to the steering cylinder displacement. The PUMP-3 is designed to achieve an HO to HO time of 9 to 15 seconds with 262 cm³ (16 cu.in) cylinders.
