ESCRIPTION
The Accu-Steer HPU100 pumpset is a continuous running pumpset designed to interface
hydraulic steering systems with electric or autopilot control. As described, the motor runs
continuously when started and the output oil is directed to the port or starboard line by
operating the four-way solenoid valve mounted on the pumpset. Its compact and rugged
construction provides ease of installation along with long life operation. This unit is available
in both 12 VDC and 24 VDC configurations.
This pumpset is suitable for vessels with steering actuators up to 40 cu in (820 cc) or vessels
up to 50 ft (15 m) in length. Proper pump selection and application is very important to
optimize steering performance and pump longevity.
