description
The reversible hydraulic drive pump has a small high-speed pump driven by a 12V or 24V dc permanent
magnet motor. The pump has pilot check valves to prevent back driving and a pilot operated reservoir
valve to enable the unit to drive balanced or unbalanced cylinders. The unit has port and starboard
¼ inch BSP service ports and a ¼ inch BSP reservoir port.

key points on installation
x A position should be chosen convenient for the steering system hydraulic delivery lines.
x The site should be rigid and flat to prevent excess vibration.
x Shielded from the direct effects of the elements.
x Minimise the lengths of the hydraulic lines from the pump to the cylinder and where possible, the
pump motor supply cables.
