Compact hydraulic power packs type KA and KAW The ready for connection hydraulic power pack consists of a housing (tank) with integrated motor and pump. The housing (tank) capacity can be increased by extensions. There is a horizontal and a vertical version available. A filling gauge, enables visual control of the fluid level even during operation. The electrical connection takes place via an integrated terminal box. Complete hydraulic control systems can be created by directly mounting various combinations of connection blocks and
valve banks to the hydraulic power pack. Float switch as well as temperature switch are available as option for the optimal supervision.
Features and benefits: ■ Additional auxiliary blower for an optimal exploitation of the performance ■ Tank volume can be adapted via modular tank extensions ■ Radial piston pumps ensure long service life and high reliability ■ Small filling volume minimize costs for fluid and fluid disposal ■ Matching
valve and accessories from a modular system ■ Vertical or horizontal installation ■ Optimum efficiency via fluid immersed motor, direct drive and clever cooling
Intended applications: ■ Modules for braking or rotor blade adjustment at wind power systems ■ Clamping systems for machine tools and jigs ■ Torque wrenches ■ Riveting and clinching ■ Presses ■ Handling systems
