Our New Gear Pump Offers Industry-Leading Reliability and Performance in a Smaller, Lighter, Quieter Package.We are excited to introduce our new 2 and 3L configurations suitable for cylinders all the way to 40Ci.

Cost Savings – the increased efficiency and performance means the pumps can be used with smaller autopilot course computers than equivalent drive units.

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.

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.

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.

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.

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:

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.

A wide variety of reversing hydraulic pump options are available to you, such as new, used.You can also choose from piston pump, gear pump and vane pump reversing hydraulic pump,as well as from 1 year, 6 months, and 1.5 years reversing hydraulic pump, and whether reversing hydraulic pump is hydraulic power units, hydraulic pumps, or fittings.

Manufactured in our factory in the UK and designed for the marine autopilot market, these quiet gear pumps are the drives of choice for major autopilot manufacturers around the world.  The range from 0.6 to 2.5 litres per minute, is water resistant to IP67 and fully certified to the Recreational Craft Directive (including ignition protection) and the navigational EMC standard.  With low power consumption and high performance, these pumps are ideal for all types of marine craft and other applications from snow-blowers to dentists chairs.

Raymarine Evolution pilots connect to hydraulic steering systems using a rugged hydraulic pump matched to the capacity of the hydraulic steering system.

The Accu-Steer HRP Series pump sets are designed to interface hydraulic steering systems with autopilot and electric steering controls. The output flow from the pump set determines the speed of the rudder. These three pumps interface with most autopilots.

Made in the USA GROCO Gear Pumps are self-priming, instantly reversible, and are capable of operation in either direction. Relatively low flow (less than vane pumps) makes them suitable for duties such as deck-wash, fuel transfer, ballast transfer, and oil change. All models have an ignition protected motor, #316 stainless steel shaft, and are available in models that provide reversing (R), remote reversing (RR), and reversing with touchpad (RT) control options.
