Hydraulic Pumps
Raymarine SmartPilots interface to hydraulic steering systems using a rugged hydraulic pump that is matched to the capacity of your vessel’s hydraulic steering system. To match a Raymarine hydraulic pump to your vessel you need to learn the size (in cubic inches) of the actual hydraulic cylinder ram or rams that are mounted to the rudder on inboard engine boats or the ram mounted to the drive on outboard engine boats. Your steering system documentation will have this information.
Raymarine autopilot hydraulic pumps are available in several sizes to accommodate a broad range of steering cylinder capacities. The table below illustrates the capacity of each type of Raymarine hydraulic autopilot pump when used with the corresponding SmartPilot corepack.
Type 0.5 Pump 12V
Reversing hydraulic pump for use with steering systems equipped with 3.1–6.7 cubic inch (50cc –110cc) hydraulic steering rams.
Type 1 Pump 12V
Reversing hydraulic pump for use with steering systems equipped with 4.9–14 cubic inch (80cc – 230cc) hydraulic steering rams.
Type 1 Pump 24V
Reversing hydraulic pump for use with steering systems equipped with 4.9–14 cubic inch (80cc – 230cc) hydraulic steering rams. Compatible with 400 Series corepacks
Type 2 Pump 12V
Reversing hydraulic pump for use with steering systems equipped with 9.8–21 cubic inch (160-350cc) hydraulic steering rams. Compatible with 400 Series corepacks.
Type 2 Pump 24V
Reversing hydraulic pump for use with steering systems equipped with 9.8–21 cubic inch (160-350cc) hydraulic steering rams. Compatible with 400 Series corepacks.
Type 3 Pump 12V
Reversing hydraulic pump for use with steering systems equipped with 21-30.5 cubic inch (350-500 cc) hydraulic steering rams. Compatible with 400 Series corepacks.
Type 3 Pump 24V
Reversing hydraulic pump for use with steering systems equipped with 21-30.5 cubic inch (350-500 cc) hydraulic steering rams. Compatible with 400 Series corepacks.
NB Hydraulic steering systems with steering rams over 30.5 cubic inches require our larger constant running hydraulic pumps used in conjunction with our SPX 30 corepacks.
