The Husqvarna PP 518 power pack is the next step in ensuring hydraulic equipment is supplied with enough power to handle any job. It replaces the PP 418 power pack with an improved front-end control panel and reduced noise. The PP 518 is a highly portable, self-contained power pack. It creates optimum power with precise flow, due to the hydrostatic pump system, which does not use engine rpms to regulate flow. This provides more consistent and accurate flow for any hydraulic tool requiring five, eight, or 10 gpm flow at 2,000 psi.
