Octopus Constant Running pumps are used in larger, heavy duty hydraulic steering systems where normal reversing pumps cannot be used. The precision pump includes an inbuilt hydraulic fluid reservoir and a tandem center solenoid control valve.  Available with AC or DC motors.

Pump Selection

The pump selected must match the size of the vessels steering ram and the power supply capability of the autopilot must also be considered.  For optimum autopilot performance the pump should be able to drive the rudder hardover from lock to lock within 13-15 seconds.  The drive flow rate should be approximately four times that of the steering ram volume.
