Hydraulic Power Units

The Power Units, 165 Series are completely self-contained with a DC motor, gear pump, reservoir, internal valving, load hold checks and relief valves. Parker designed these units for intermittent duty and offers them in three standard pump sizes producing flows of .032, .050 and .065 cubic inches per revolution. The units are available for single or bi-directional application with a number of hydraulic circuit options. Single direction units are commonly used to charge accumulators, power single direction hydraulic motors and single acting cylinders, as well as for use with multi-function circuits with external valving. Bi-directional units are commonly used to operate double acting cylinders and reversible motors.
