HYDRAULICS 28 HYDRAULICS & PNEUMATICS June 2022 www.hpmag.co.uk Diesel power packs 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 PP19 and PP44 units are diesel powered and both 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 which 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. Variable pumps within the power packs allow pressure & flow to be adjusted for specific applications. Key Features and Benefits PP11 and PP15 Electric Power Packs Voltage Options allow for global supply Series of application specific pendants Controls can be selected Safety: Emergency stop buttons are provided on the power pack and the control pendant. Power Packs enclosed within a protective frame Forklift truck and vertical lift points Removable castor trolley available as an accessory. PP19 and PP44 Diesel Power Packs Emission levels allow for global supply Spark Arrestor Series of optional application specific hydraulic controls Series of optional application specific hose kits Power Packs enclosed within a protective frame Forklift truck and vertical lift points Pressureless switch to remove pressure and flow www.enerpac.com The new PP-Series electric and diesel-powered units from Enerpac are purpose-designed to supply hydraulic flow to Enerpac portable machine tools, including flange facing machines, clamshell cutters, hot tapping machines and decommissioning tools. The units are also compatible with other brands of portable machine tools. The new series includes a total of four hydraulic power packs comprising of two electric and two diesel powered models. Electric powered hydraulic power packs Portable machine tool operators with access to an electric supply can choose between the 11 or 15 kW models – each available with a choice of voltage options for use throughout the world. Machine specific control pendants 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, this is of little use to control other machine types such as gantry mills, or 3-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 means a perfect match can be supplied to suit with the specific machine tool. A choice of hose kits 10-meter hose kits are supplied as standard and longer hose kits are available as accessories for single-supply, dual-supply and triple-supply applications. Triple supply hose kits allow 3 hydraulic motors to be connected to the power pack at the same time – which allows the operator to select the required axis (x or y) from the pendant. Machine operators choosing an electric power pack can also benefit from an optional cart to enable easy positioning and storage within a workshop environment.
