Key Features
  • For steering cylinders up to 200cu in (3500cc)Available as a simple pump unit, a motor and reservoir combination to replace an engine driven pump or fitted with a direction solenoid valveDC models: 12v, 24v or 32v.

  • AC models: 110v/220v single phase or 220/460/ 575v three phase.

  • Wide flow range - units available with max flow rates from 1gpm (4000 cc/min) up to 3.5gpm (13,000 cc/min) with adjustable flow control and dual speed options.

  • Adjustable pressure relief valve (100 - 1200psi).

  • Inbuilt pressure gauge.

  • Heavy-duty ball bearing electric motors.

  • Long life mechanical seal between motor and pump instead of a lip seal, which wears a groove in the shaft.

  • Large capacity reservoir for cool running in all climates.

Powerful -  Suitable for steering cylinders up to 3500cc (200cu in).
Economical - High performance, low power consumption, compact design.
Fully Integrated Design - No complicated external pipes or fittings to break or leak.

​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.

Unparralleled Performance, Reliability and Durability!

We have been designing, manufacturing and marketing Autopilot Drives for over 25 years. We hold patents on several unique devices that enhance drive performance and supply drives to most of the Marine Industry's leading Autopilot Manufactures for resale within their autopilot packages.
