Autopilot Pump Type 1 Adjustable Reversing 12V Up To 15 CI Cylinder 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. SAVE ON INSTALLATION COSTS A professional installation should always have a method of isolating the pump from the steering system - Octopus pumps feature inbuilt shut off valves in the pump manifold. ADJUSTABLE FLOW RATE A pump that does not have variable flow (unless dedicated to a range of cylinders such as our fixed 0.8L pump) will be operating too fast or too slow in 90% of cases.  Autopilot manufacturers get around this problem by adjusting the output to the pump to compensate, which either forces the pump to operate for longer periods of time which increases power consumption and wear on the parts, or it will operate at high pressure for short periods of time - also putting unnecessary strain and wear on the system. Octopus Variable Flow Reversing Pumps precisely control the speed of the ram, reducing unnecessary battery consumption, pressure, strain and wear on the hydraulic system. Getting the best steering performance for the boat. The flow rate of the pump can be set to get the best hard over time (cylinder ram speed) for the particular boat.  Features: Reliable - Piston pump technology with only three moving parts Twice 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
