EV212V — Non-reversible hydraulic pumps with adjustable flow

The FURUNO EV212V is a non-reversible marine hydraulic power unit designed to be integrated into an existing hydraulic steering system. It is specifically used to drive an autopilot, enabling precise control of the vessel's heading.

The primary function of the FURUNO EV212V is to provide the hydraulic power required by the steering ram to execute autopilot commands. It enables precise and rapid course corrections, contributing to stable navigation.

The FURUNO EV212V offers an adjustable flow range from 0.2 to 2 litres per minute (L/min). This setting allows the autopilot system's response to be adapted to the vessel's specific characteristics.

The flow rate of the FURUNO EV212V is precisely adjustable via a dedicated screw. This feature allows fine-tuning of the time required for a cylinder to travel from stop to stop, optimizing autopilot performance.

A non-reversible hydraulic power pack, such as the EV212V, means the pump runs continuously in one direction. Direction control of the cylinder is handled by an integrated solenoid valve distributor that directs the hydraulic fluid, rather than reversing the pump's rotation direction.

Advantages of a non-reversible hydraulic pump include:

Increased precision: Solenoid-controlled operation enables finer and faster course corrections.Less wear: The pump runs continuously in one direction, which can reduce wear from frequent starts/stops or direction reversals.Reduction of "pumping": Lower risk of over-correction or abrupt rudder movements.

Yes, the FURUNO EV212V integrates a solenoid valve distributor. These solenoid valves are essential for directing the hydraulic flow to the rudder actuator, enabling precise steering control by the autopilot.

The FURUNO EV212V operates on a 12 V DC (direct current) power supply.

No, the FURUNO EV212V is designed to integrate into an existing hydraulic steering system and uses the oil reservoir already present in that system. It does not have a dedicated oil reservoir.

The purpose of flow adjustment is to optimize the responsiveness and precision of the autopilot based on the vessel's size, rudder type, and sailing conditions. A lower flow rate may suit small boats or calm seas, while a higher flow rate may be necessary for larger vessels or rough seas to ensure rapid corrections.

The FURUNO EV212V is suitable for hydraulic steering rams with a maximum displacement of 432 cm³.

The EV212V is compatible with most standard marine hydraulic steering systems, provided the cylinder displacement is less than or equal to 432 cm³ and the system is designed for integration with an autopilot.

No, the FURUNO EV212V is a hydraulic unit and is exclusively designed to operate with hydraulic steering systems. It is not compatible with mechanical steering systems.

The FURUNO EV212V is suitable for boats equipped with a hydraulic steering system whose cylinder has a maximum displacement of 432 cm³. This generally corresponds to a wide range of boats, from small to medium-sized, but the exact size will depend on the specific design of the tiller and cylinder.

No, the FURUNO EV212V is specifically designed to operate on a 12V DC power supply. It is not compatible with 24V systems.

The FURUNO EV212V requires a 12 V DC power supply. Ensure the power circuit is correctly sized to handle the hydraulic pump's consumption.

The EV212V hydraulic pump must be installed in the hydraulic circuit of the rudder system, typically between the manual pump (or the steering block) and the rudder actuator. It is recommended to mount it close to the actuator to minimize the length of the hydraulic hoses.

Yes, installing the FURUNO EV212V requires marine hydraulics and electrical skills. It is strongly recommended to use a qualified professional for installation to ensure system safety and proper operation.

No, the FURUNO EV212V is typically supplied alone. The hoses and hydraulic fittings required for integration into the existing steering system must be purchased separately, based on your installation specifications.
