Enerpac Launches Hydraulic Power Packs for Portable Machine Tools

Enerpac recently announced the new PP-Series electric and diesel-powered power packs to supply hydraulic flow to Enerpac portable machine tools, including flange facing machines, clamshell cutters, hot tapping machines, and decommissioning tools.

The hydraulic power packs are also compatible with other brands of portable machine tools.

The Enerpac PP-Series includes four hydraulic power packs comprising two electric and two diesel-powered models. Variable pumps within the power packs allow pressure and flow to be adjusted for specific applications.

Portable machine tool operators with access to an electric power supply can choose between the electric powered hydraulic power pack 11 or 15 kW models, each available with a choice of voltage options for use throughout the world.

Many manufacturers of hydraulic power packs provide a simple general-purpose control pendant as standard with each unit. Although this is adequate for simple machining tools, it is of little use to control other machine types such as gantry mills or three-axis milling machines.

To meet these different applications, customers buying an Enerpac Electric PP-Series Power Pack can get exactly what they need. The range of pendant options offered provides a perfect match to suit the specific machine tool. In addition, for operator safety, emergency stop buttons are provided on the power pack and the control pendant.

For working in remote locations, customers have a choice of 19 and 44 kW units. These more powerful power packs are the optimum choice for larger machine tools used for operations such as hot tapping and decommissioning.

Both the Enerpac Diesel PP-Series PP19 and PP44 units are diesel powered and meet the EU Stage V and EPA tier-4 final regulations for emissions. Each includes a 50-liter diesel tank, which, in the case of the PP44, can provide up to 12 hours run time at maximum torque. Also included in the diesel power packs is a spark arrester for added safety in explosive environments.

Unlike the electric units that work with pendants to provide control, the PP19 and PP44 power packs require a separate hydraulic control panel and machine-specific hose kits. The hydraulic control is connected to both the machine tool and the hydraulic power pack. The control panel houses all the controls needed for a specific machine’s requirement. In addition, the Diesel PP-Series power pack features a pressure-less switch to remove pressure and flow.
