Constant Running Hydraulic Pump - Installation Guide 3
Introduction
Product description
Welcome to the installation guide for the Raymarine constant running
(CR) hydraulic pump. This product is intended to operate the boat’s
steering mechanism as part of a Raymarine autopilot system.
The pump provides an ideal drive system for large boats and heavy
duty steering applications. 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 and bypass valve.
The pump contains a built-in reservoir that holds hydraulic fluid and
an integral solenoid valve that controls the flow of hydraulic fluid to
the steering ram. The autopilot system steers the boat by using the
solenoid control valves to control the flow of hydraulic fluid to the
steering ram.
