Never installed Octopus type3 hydraulic reversing pump. 12v, up to 30ci cylinder.

Autopilot Pump Type 3 Adjustable Reversing 12V Up to 30CI Cylinder

Features:

• RELIABLE - Piston pump technology with only three moving parts
• TWIC THE POWER - Delivers over twice the hydraulic output per watt of input
• HALF THE POWER CONSUMPTION - Accurate ram positioning means fewer course corrections
• ADJUSTABLE FLOW RATE - Configure performance to suit your vessel
• EASY SERVICING - Shut off valves allow removal without draining steering system

TWICE THE POWER

The unique Octopus piston pump delivers over twice the hydraulic output per watt of input than a standard hydraulic gear pump.

HALF THE POWER CONSUMPTION

Gear pumps leak oil between the gears, while a piston (such as used in car engines) does not.  This means the piston pump will place the cylinder ram exactly where it is required, positioning the rudder accurately.  This gives far sharper steering, reducingunnecessary course corrections meaning battery consumption on Octopus pumps is up to half that of other pumps.

PINPOINT ACCURACY

Leading autopilot manufacturers choose Octopus pumps for their non RFB pilot systems which do not have a Rudder Feedback unit. Previously, slop in the system caused by gear leakage meant that a Rudder Feedback unit was necessary to tell the pilot the exact rudder position. As Octopus pumps will always bring the ram back to the required position the Rudder Feedback unit is not required, which also greatly simplifies installation.
