« Technical analysis: Navico PUMP-5 hydraulic pump for 24V autopilots »

The Navico PUMP-5 hydraulic pump is a key component for autopilot systems on larger vessels. Its 24V power supply and high flow rate of 3.0 L/min make it ideal for hydraulic circuits requiring fast response and the ability to actuate large rudder cylinders (up to 960 cm³).

Integration is a strong point: it is designed to work optimally with Navico NAC-3 or AC42 autopilot computers, ensuring seamless compatibility within the navigation ecosystem. The built-in check valves are critical for safety and performance, ensuring the rudder holds its position even in the event of an electrical failure—a key advantage in offshore or rough-sea sailing. During installation, special attention must be paid to power cable sizing (minimum AWG 12 recommended) and complete bleeding of the hydraulic system to prevent cavitation or slow response. Choosing the right tubing material, such as 3/8" OD annealed copper, is also critical for the circuit’s longevity and reliability.

This pump is aimed at boat owners seeking a robust, integrated autopilot solution capable of handling demanding hydraulic steering systems. Its reversible design is an advantage for complex tiller configurations, offering great installation flexibility.

Frequently Asked Questions

Need help? Contact us

What is the required supply voltage for the Navico PUMP-5 pump?

The Navico PUMP-5 pump is designed to operate exclusively with a 24V DC power supply.

What is the nominal hydraulic flow rate of the PUMP-5 pump?

The PUMP-5 pump delivers a nominal hydraulic flow rate of 3.0 litres per minute, which is equivalent to 183 cubic inches per minute.

For which cylinder displacement range is the PUMP-5 steering pump suitable?

The PUMP-5 pump is specifically designed for hydraulic cylinders with a displacement between 290 cm³ and 960 cm³ (17.7 to 58.5 cubic inches).

What types of hydraulic connections are used on the PUMP-5 pump?

The PUMP-5 pump is equipped with O-Ring Boss (ORB) fittings for connection to your boat's hydraulic circuit.

What is the weight of the Navico PUMP-5 pump?

The total weight of the Navico PUMP-5 pump is 3 kg.

What are the overall dimensions of the PUMP-5 pump?

The overall length (OAL) of the Navico PUMP-5 pump is 214 mm.

Is the PUMP-5 pump a reversible hydraulic pump?

Yes, the Navico PUMP-5 is a reversible gear hydraulic pump, a key feature for autopilot systems operation.

Does the PUMP-5 pump include non-return valves?

Yes, the PUMP-5 pump is equipped with integrated check valves. These valves provide positive load retention, ensuring the rudder's position remains stable even when the motor is not powered.

What are the typical and peak electrical currents for the PUMP-5 pump?

For the PUMP-5 pump (24V, 3.0 Lpm), typical electrical current draw is 6 to 10 amperes. Peak current can reach 15 amperes at 50 bar.

What is the country of origin of the Navico PUMP-5 pump?

The country of origin for the Navico PUMP-5 pump is Canada.

What types of fittings are included with the PUMP-5 pump?

The PUMP-5 pump is supplied with three ORB-5 to 9/16 UNF fittings to facilitate installation in your boat's hydraulic circuit.

Which tube material is recommended for the hydraulic circuit of the PUMP-5 pump?

For the hydraulic circuit, it is recommended to use a soft annealed copper tube with an outer diameter (OD) of 3/8", type L ASTM B88, with a minimum wall thickness of 0.030".

What is the minimum recommended cable size to power the PUMP-5 pump?

For pump PUMP-5 (24V, 3.0 Lpm), the minimum recommended electrical cable size is AWG 12 (4.0 mm²). Using the correct cable size is critical to ensure optimal pump performance and prevent underpowering.

What to do if the pump motor does not start during installation?

If the pump motor is not running, the first recommended action is to check the voltage with a multimeter to ensure appropriate voltage is being applied to the motor.

What to do if the wheel-to-wheel time is too long after installing the pump?

If the time between helm movements is excessive, this may indicate low voltage at the motor. It is then recommended to confirm that the size of the electrical cable to the motor is correct. An undersized pump for the steering ram may also be a cause, in which case a higher-capacity pump should be considered.

How to assemble ORB fittings on the pump ports?

Before assembling the ORB fittings into the pump ports, inspect the threads of the port and the connector to ensure they are free of dirt, burrs, or any other obstruction, in order to guarantee a perfect seal.

With which autopilot computers is the PUMP-5 pump compatible?

The PUMP-5 pump is compatible with Navico NAC-3 and AC42 autopilot computers.

Is the PUMP-5 pump compatible with Navico's SteadySteer technology?

Yes, the PUMP-5 pump is fully compatible with Navico’s SteadySteer technology, enabling seamless integration into existing systems.

How to ensure the pump is correctly sized for my steering ram?

For correct sizing, you must consider both the size of your steering cylinder and the time recommended by the ship/autopilot manufacturer for a hard-over to hard-over (HO to HO) rudder movement. The PUMP-5 pump is designed for cylinders from 290 to 960 cm³ and targets an HO to HO time of 9 to 14 seconds for this range.

Is the Navico PUMP-5 pump compatible with 12V electrical systems?

No, the Navico PUMP-5 pump (model 000-15447-002) is specifically designed to operate with a 24V DC power supply. It is not compatible with 12V systems.
