Common Question of Octopus Gear Pump
What cylinder fits this pump?
The Octopus Hydraulic Gear Pump is listed for hydraulic cylinders from 30 to 40 cubic inches and uses 12V power. Confirm cylinder volume, hydraulic fittings, hoses, control computer, battery, wiring, and hydraulic autopilot system compatibility before installation.
What voltage does it use?
It uses 12 volts according to the product listing. Confirm battery capacity, cable gauge, fuse or circuit breaker, pump current, polarity, grounding, hydraulic fittings, and control-unit connections before wiring for dependable steering operation.
Is it an anchor windlass pump?
No. The Octopus gear pump moves hydraulic steering fluid for autopilot operation and does not operate a gypsy, drum, chain, or anchor rope. It is not an electric anchor windlass. Use dedicated equipment for marine anchoring.
