[LW] [LW11] Pump position

[Derek - Raymarine - Moderator]

Hi Felipe,

Thank you for the feedback, at 1500cc this is a very big ram, is it possible to doublecheck this and confirm the ram is single or double acting? is there only one ram too? ( As shown in the attachment you sent).
Can you identify the full extent of the travel of the ram, although it might have a total capacity of 1500cc, does it use the full stroke from fully port to fully starboard?

If it is 1500cc and does use the full travel, then you would need to use the ACU300 and a solenoid operated constant running pump with a flow rate of something like 9litres/min, ideally an adjustable flow rate up to this level would be an advantage, since you can then tune the flow rate to suit the characteristics of the boat. bear in mind that at higher speeds the rudder will need to move much less and slower too.

Thanks
Derek
