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. There is a simple equation to calculate the 
hard over time:
	HARDOVER TIME = CYLINDER (RAM) CAPACITY x 60
	FLOW RATE
	Example
	A boat has a 200cc steering cylinder (ram) and a 12 volt 
system. So either the OCTAF1012 or the OCTAF1212 would be suitable (see table 
below left). For this example we are using the OCTAF1212 which has a minimum 
flow rate of 600cc/min and a maximum flow rate of 1200cc/min:
	MIN HARDOVER TIME: 200 x 60 = 20 sec
	600
	MAX HARDOVER TIME: 200 x 60 = 10 sec
	1200
	The flow rate on the pump can be adjusted so that the hard over time is 
between 10 & 20 seconds - select which is most suitable for the particular boat.
