raymarine type 1 hydraulic pump factory

Boats with traditional hydraulic steering systems will use an Evolution autopilot driven by a hydraulic pump. The pump connects to the boat"s hydraulic steering lines and allow the autopilot to steer the boat by controlling the flow of fluid through the boat"s steering system. The hydraulic pump is controlled by the Evolution autopilot Actuator Control Unit (ACU.)

The Type 1 hydraulic drive is compatible with both S1/S1G and S2/S2G corepacks. Use the table below to determine the Type 1 hydraulic drive"s capacity when used with each corepack

The reversing hydraulic pump is designed to be used in conjunction with a steering system equipped with 4.9-14 cubic inch (80cc - 230cc) hydraulic steering rams.

The reversing hydraulic pump is a high quality, reliable product designed for use with steering systems equipped with 4.9-14 cubic inch (80cc - 230cc) hydraulic steering rams.

This pump will allow the operator to move the steering ram in either direction by simply reversing the flow of hydraulic fluid from one side of the pump to the other.

Raymarine Evolution pilots connect to hydraulic steering systems using a rugged hydraulic pump matched to the capacity of the hydraulic steering system.

You"ll need to find out the size (in cc) of the hydraulic cylinder ram(s) mounted to the rudder or inboard engined boats, or to the drive unit on outboard engined boats. Your steering system documentation will have this information.

(also known as the Raymarine reversing hydraulic pump). This product is intended to operate the boat’s steering mechanism as part of a Raymarine autopilot system. It is primarily designed for use on boats with an existing hydraulic steering system. Alternatively, you can use this pump on a boat with mechanical steering in conjunction with a secondary steering ram.

Hydraulic Pump - Installation Guide • Try to keep hydraulic fluid loss to a minimum when installing the pump. This will reduce the time and effort required to bleed the system of trapped air after installation: • • WARNING: Before disconnecting any pipes on pressurized systems, you MUST release the pressure at the reservoir by following the manufacturer’s instructions.

Hydraulic Pump - Installation Guide Two line pressurized systems Two line pressurized systems have an external pressurized reservoir. This reduces the possibility of introducing air into the system and reduces any steering ‘sponginess’ caused by pipe expansion.

Make sure the power supply is switched off before you make any electrical connections. The hydraulic pump has electrical connections for its motor: a red and a black cable. Note: To meet current EMC legislation, you must NOT untwist the pump cables, and you must NOT remove the suppression ferrite.

Post-installation check WARNING: Keep clear of moving steering systems at all times. Protect moving parts from access during normal use.

Bleeding the system Bleeding the hydraulic system correctly is one of the most important steps when installing the autopilot hydraulic pump. If there is any air in the system the steering will feel spongy, particularly when you turn the wheel to hardover.
