This unit is designed for many shipboard and industrial applications where low pressure and a small source of hydraulic pressure is required.
It is available with either a 12 or 24 Volt DC motor and is intended for intermittent use only. It lends itself extremely well to manual steering systems where a source of pressure is required to operate the steering cylinder in conjunction with an autopilot. It could also be used in raising and lowering hatches, masts and tables.
The maximum amperage that the motor can handle on an intermittent basis is approximately 30 amps for a 12 volt motor and 15 amps for a 24 volt motor. We do, however, recommend that the motor should not draw any more than 16 amps for the 12 volt motor and 8 amps for the 24 volt motor. The table below indicates the capabilities of the motor. Adjustable safety valves for both port and starboard are provided and flow control screws provide adjustment for the variable delivery from 40 to 250 cubic inches per minute. The lock valve fitted on the pump is to prevent hydraulic feedback from the steering system. Both pump and motor are equipped with ball bearings. The pump is made of silicon bronze, stainless steel hardware with hardened steel pistons and wear plate.
The centre terminal block is for the directional control circuit and the other blocks are for the power in and power to the motor. The motor leads are located internally in the housing.
