PISTON PUMP, 1L/MIN, 24V, ORB PORTS

The unique Octopus piston pump delivers over twice the hydraulic output per watt of input than a standard hydraulic gear pump. 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, reducing unnecessary course corrections, meaning battery consumption on Octopus pumps is up to half that of other pumps. 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.
