Pump PUMP-2 12 V 0.8 L

The Navico PUMP-2 12V 0.8L (reference 000-15444-002) is a reversible gear hydraulic pump designed specifically for marine autopilot systems. It provides precise and responsive control of steering for assisted navigation.

The Navico PUMP-2 pump operates on a 12V DC power supply.

The PUMP-2 pump has a nominal flow rate of 0.8 litres per minute (49 cu.in/min).

The overall length (OAL) of the Navico PUMP-2 pump is 179 mm.

The Navico PUMP-2 is a reversible hydraulic gear pump.

The typical current measured for the PUMP-2 pump is between 4 and 7 amperes. Peak current can reach 11 amperes at 50 bar.

The PUMP-2 pump is compatible with hydraulic cylinders having a displacement between 98 cm³ and 131 cm³ (6 to 8 cu.in) to achieve a 9 to 15 second rudder-to-rudder response time.

Yes, the Navico PUMP-2 pump is compatible with SteadySteer technology.

To use the SteadySteer function with the PUMP-2 pump, an NAC-2 or AC12 autopilot computer is required.

Yes, the Navico PUMP-2 pump is designed to be used with marine autopilot systems to provide steering control.

The PUMP-2 pump uses O-Ring Boss (ORB) connections.

The PUMP-2 pump is supplied with 3 ORB-5 fittings to 9/16 UNF.

For hydraulic installation, the recommended tube material (North American standard) is 3/8" OD (outer diameter) soft copper, ASTM B88 type L, with a minimum wall thickness of 0.030".

For optimal performance, the minimum recommended electrical cable size for the PUMP-2 pump (12V, 0.8 lpm) is AWG 12 (4.0mm²).

To avoid excessive play in the wheel (bar to bar), ensure that:

The motor power supply voltage is correct. The motor power cable gauge is appropriate (minimum AWG 12 / 4.0mm²). The pump is correctly sized for the steering cylinder (compatible with 98 cm³ - 131 cm³ for a 9-15 second cycle).

If the pump motor is not running, the first step is to check the supply voltage with a multimeter to ensure that voltage is actually being applied to the motor.

If the engine is running but the rudder does not move, this usually indicates that the system is not filled with oil. Top up the oil and bleed the hydraulic system.

To select the correct pump size, you must consider both the volume of your steering cylinder and the time recommended by the boat or autopilot manufacturer for a full rudder swing (hard over to hard over). The PUMP-2 pump is suitable for cylinders from 98 cm³ to 131 cm³ for a swing time of 9 to 15 seconds.

The Navico PUMP-2 pump is covered by Navico Group's standard manufacturer warranty. This warranty covers material and manufacturing defects in accordance with the terms and conditions specified by Navico Group.
