The Octopus Adjustable Reversing Pumps are used when hydraulic steering is fitted on boats up to 65 feet L.O.A.
The pumps are switched on by the automatic pilot and make a steering correction to left or right determined by the direction of rotation of the pump motor. The motors are of the permanent magnetic type and reversing direction is accomplished by reversing the motor input current.
The pump has only three moving parts and requires no complicated check valves to prevent rudder movement when de-energized. Output flow is completely adjustable to 50% of rated flow allowing the pump output to be adjusted precisely to the volume of steering cylinder fitted. The pump is exceptionally reliable and delivers more than twice the hydraulic output per watt of input than gear pumps manufactured by competitors.
Motors are heavy duty, a full 85mm in diameter with long brushes and sealed ball bearings for long service life. The molded rubber mounting foot can be rotated to allow the pump to be mounted on any surface.
A useful range of accessories can be used to enhance the pump by incorporating added valves and solid state FET switching. The valves mount directly to the pump body. The FET switch mounts adjacent to the pump. No other autopilot pump made offers such advantages.
Benefits of the Octopus Reversing Pumps
Piston pump technology giving higher efficiency and accuracy Fewer moving parts giving increased reliability Variable flow rate to make sure the pump is matched as accurately as possible to the manual steering system Professional cut off valves for simple servicing.

With an average rainfall of only 12.5 inches per year and a population that's growing faster than the country's , Arizona is a state that faces unique challenges, especially when it comes to clean, safe water. The Water Quality Division of the Arizona Department of Environmental Quality (ADEQ) protects and enhances public health and the environment by monitoring and regulating drinking water. And although they make use of the latest scientific methods and new technology, given the current state of Arizona's water system, they also rely upon low-tech equipment and cooperation from members of the community to monitor water quality in the state. Team members in the Groundwater Protection Program work to sample, test and characterize groundwater quality in all 51 of Arizona’s basins.Read More
William Anderegg, assistant professor of biology at the University of Utah, has spent years studying drought-stricken trees all over the world. As climate change is expected to cause increased drought severity in the future, the work of Anderegg and his colleagues becomes increasingly important. In a previous interview for the Environmental Monitor , Anderegg found that a tree’s hydraulic safety margin was the best indicator of whether a tree would survive drought. The hydraulic safety margin is an expression of how the tree reacts under drought conditions, where there is very little water being pulled up the tree’s transport system and air is being pulled up instead. “It’s like a heart attack for the tree,” he noted.Read More
You've probably heard of the Four Corners region of the United States; that's where the corners of Arizona, New Mexico, Utah and Colorado meet at one point. These same four states are also part of the Colorado River Storage Project (CRSP), which began to change the face of the American West in 1956, enabling the population explosions in places like Phoenix and Los Angeles to continue thanks to usable water. Glen Canyon Dam is 220 meters high and 480 meters wide, and this massive structure has changed this section of the Colorado River all the way to Lake Mead dramatically. It has also increased low-flow magnitudes, decreased peak flow magnitudes and volumes and caused fluctuations in daily discharge levels that the area relies upon for generation of hydroelectric power.Read More
