The portable, self-contained PP 518 power pack supplies hydraulic equipment such as wall saws, drill motors, and power cutters with enough power to handle any job. The power pack creates optimum power with precise flow using a unique hydrostatic pump system that does not use engine rpms to regulate flow. Use for hydraulic tools requiring 5, 8, or 10 gpm flow at 2000 psi. Controls and hose attachments are located on the front of the machine, improving operator efficiency.
