Parker Oildyne 108 Series Hydraulic Power Units

The compact 108 Series power units are completely self-contained with an AC or DC motor, gear pump, reservoir, internal valving, load hold checks and relief valves. Designed by Parker for intermittent service, these units come in four standard pump sizes.

Series units are available with single- or bi-directional rotation. Single units are commonly used to charge accumulators, power one-direction hydraulic motors and cylinders, provide pilot flow to servo valves, pressurize lube systems and supply multifunction circuits with external valving. Bi-directional, reversible units operate double-acting cylinders and two-way motors. Typical applications for these units are found in positioning systems, recreational vehicles, clamping, cycling, and lifting operations.
