The HYCON HPP18E FLEX open center power pack is an advanced hydraulic power source, which regulates the revolutions of the motor and thereby the oil flow supplied by means of a built-in frequency converter. The power pack covers variable flow outputs from 10 to 46 LPM / 3 to 12 GPM respectively at 120 bar / 1740 psi. This HYCON power pack is fully compatible with and sufficient for the common European and North American tools. A pressure relief valve is used to avoid a too high pressure of the power pack. The very efficient air cooling protects the power pack against overheating.
