Set pumpe 1,2 litre

The Garmin 1.2-litre pump kit is a key component designed for Garmin Reactor 40 autopilot systems. Its primary function is to provide precise steering control by pumping hydraulic fluid to the steering cylinders on command from the autopilot.

This high-pressure/low-volume (HPLV) hydraulic pump is specifically optimized for single-cylinder applications, with cylinder volumes ranging from 6 to 14 cubic inches.

The Garmin 1.2-litre pump kit delivers a flow rate of 1.2 litres per minute and a maximum pressure of 1000 PSI. These specifications make it suitable for small to medium-sized vessels.

The pump is manufactured with a corrosion-resistant aluminum alloy body. It also features upgraded ORB hydraulic ports and threaded cable clamps, contributing to increased durability in the marine environment.

No, this pump is designed for use only with Garmin autopilot systems. Using it with another system may damage the system, the pump, or the vessel.

It is imperative that the boat's steering system has a vented reservoir. Installing this pump with a non-vented reservoir will damage the pump. The vent hole is typically located in the filler cap of the highest helm station.

The autopilot system, including this pump, must be installed by a qualified marine installer. Specific knowledge of marine steering and electrical systems is required for correct installation.

For pump installation, the following tools and hydraulic equipment are required:

Tools: Safety glasses, drill and bits, wrenches, wire cutters/strippers, screwdrivers (Phillips and flathead), cable ties, marine corrosion inhibitor spray. Mounting screws are included in the pump kit, but you may need to supply additional screws if the included ones are unsuitable for your mounting surface.

Hydraulic equipment: Hydraulic hoses of -4 [6 mm (1/4 in) ID] or larger, with machine-crimped or field-replaceable fittings rated for a minimum of 1000 psi. Also required: hydraulic T-fittings, hydraulic shutoff valves, liquid thread sealant (such as LOCTITE 567), hydraulic bleeding equipment, and hydraulic fluid. Note that fittings are not included with the pump or check valve.

The pump must be installed in a dry location, protected from water and harsh weather. It must be located within 0.5 meters (19 inches) of the ECU and within 3 meters (10 feet) of the steering ram. Additionally, it should be mounted horizontally if possible, or vertically with the pump head connectors facing upward if horizontal mounting is not feasible.

No, the cables connecting the pump to the ECU cannot be extended. The pump must be located within 0.5 meters (19 inches) of the ECU.

For all hydraulic connections, including the return line, you must use hydraulic hoses of -4 [6 mm (1/4 in) ID] or larger, with machine-crimped or field-replaceable fittings having a minimum rated pressure of 1000 psi.

For hydraulic fittings with an O-ring (such as ORB and ORFS fittings), do not use any thread sealant. For fittings without an O-ring, use a liquid thread sealant, such as LOCTITE 567, strictly following the manufacturer's curing time. Do not use thread tape (e.g., Teflon tape) or sealant paste, as debris could enter the system and cause damage.

You must disconnect the necessary hoses from the hydraulic system. Add a T-connector to the port and starboard hoses between the helm station and the steering ram. If the boat has no return hose connected to the helm station, add one from the helm station’s return port to the pump. If a return hose already exists, add a T-connector. Then connect the hoses from the T-connectors to the appropriate ports on the pump and the return hose to the pump’s central port.

After installing the pump and hydraulic hoses, you must follow the instructions provided with your Garmin autopilot system to bleed the hydraulic system. A pressurized bleed is required after installing the check valve to fill the pump and valve with hydraulic fluid.

Yes, after completing the autopilot installation, it is recommended to update the software before performing the configuration process. If the system is connected to an NMEA 2000 network with a Garmin chartplotter, the update can be done via the chartplotter. Otherwise, an NMEA 2000 Network Updater (sold separately) is required.

After installation, it is recommended to apply a marine corrosion inhibitor spray to the pump body and manifold to ensure corrosion resistance. Garmin recommends reapplying this inhibitor once a year to extend the pump's lifespan.

Yes, this pump can be installed on an electrically assisted steering system. In this case, the pump must be installed between the cylinder and the electric assist module to function correctly. The Shadow Drive valve must be installed between the helm station and the electric assist module.

No, hydraulic fittings are not included with the pump or the check valve. The pump and the check valve use ORB-5 fittings.

The check valve is a component that can be installed to correct or prevent a boat’s tendency to gradually turn to one side without continuous manual corrections, particularly in installations with uneven rudder loads. It prevents fluid from flowing back into the pump from the steering system.
