Example of use: Liebherr hydraulic power units for test benches

Hydraulic power unit for impulse test benches

Hydraulic power unit for impulse test benches

For impulse test benches for testing hydraulic components, Liebherr offers hydraulic power units with high flexibility: The proportion of pressure and also delivery volume is adjustable and pressure testing of the components is carried out with a variable curve. To assure fast testing times, Liebherr power units fulfil the requirements of up to 60 cycles per minute. Control for regulation of the test parameters features an integrated interface in this case. The display shows the test cycle and also evaluation of the results.
