The completely self-contained devices in the 108 Series of power units come with an AC or DC motor. These compact machines also include a gear pump, a reservoir, internal valves, load hold checks, and relief valves. They were created for intermittent services. Four pump sizes are available and the flows produced by them measure: .0098, .0187, .0246, and .0321 cubic inches per revolution, depending on the model.
The type of fluid used affects performance. Locking check valves are offered for all models and there are a number of different hydraulic circuits available as well. Single or bidirectional rotation is a feature of these units. Double-acting cylinders and two-way motors can be operated using the reversible, two directional units. Meanwhile, the single units are typically used for accumulator charges and to power one-directional hydraulic motors and cylinders.
They can also be used to either facilitate pilot flow to servo valves or provided external valves to multi-function circuits.
