Reversing Pump
Reversing pumps are used when hydraulic steering is fitted on boats up to 65
feet L.O.A. (depending on rudder torque). 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 85 mm 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

Installation
The pump set should be mounted on a horizontal surface in a clean dry area.
The three hydraulic connections to the steering system should be made using
tubing, which meets the steering system manufacturer's specification. All three
hose connections must be used and under no circumstances must the pump set be
run without the compensating (breather) line connected to the steering system
reservoir.
| Optional Accessories |
| Shut Off Valve SV |
The shut off valve mounts on
the end of the pump enabling the pump unit to be disconnected from the
steering system without loss of hand steering. |
| By-Pass Valve BP12V (12 volt)
BP24V (24 volt) |
The bypass valve can be
mounted to the pump and consists of a normally open solenoid valve (which is
connected across the pump output) and a translucent plastic reservoir. When
the valve is mounted to the pump and the assembly connected to a balanced
hydraulic cylinder, the cylinder can be used to drive the rudder on vessels
with mechanical steering. No external reservoir is required. Built-in
bleeder screws allow the unit to be quickly filled and purged. |
| Unbalanced Valve UB |
The unbalanced valve fits on the pump to
adapt flow to unbalanced steering cylinders. |
Note: For larger pump sizes see our product information
sheets on Continuous Running Pump sets CRA and CRB.
