Hydraulics test bench

Precise tests for maximum safety and performance

At HK Hydraulik, we rely on our high-performance hydraulic test bench, to ensure that all repaired components function to the highest standards. Our test bench enables us to test all common hydraulic components – such as hydraulic pumps and motors – under realistic conditions, before they are used again.

Services of our test bench

Functional tests

After each repair, we carry out extensive functional tests to ensure that all components are working properly. These include:

  • Performance tests for pumps and motors
  • Testing the switching mechanisms of valves
  • Testing for leaks in cylinders

FAQ Test Bench

  • Which components can be tested on the test bench?

    We test a wide range of hydraulic components, e. g. pumps, cylinders, valves and motors.
    Thanks to infinitely variable speeds, technical options and different pressures, we are also able to test hydraulically closed, semi-closed and open circuits on our PLC computer-controlled test bench, as well as all types of tank-mounted pumps.

  • How long does a test bench test take?

    The duration of the test depends on the complexity of the component. We carry out the test directly after the repair.

  • How accurate are the tests on the test bench?

    Our self-developed and continuously modernized hydraulic test bench is one of the most efficient systems on the market. Through constant adaptation to technical progress and precise test procedures, we check every repaired component under realistic conditions. Our test procedures include:

    • Pressure tests to check the load capacity
    • Leakage tests for maximum operational safety
    • Functional tests to ensure performance

    Thanks to state-of-the-art measuring systems of our test bench, we can determine speeds and torques with an accuracy of 0.1 %. We evaluate the power consumption and output of your pumps, motors, cylinders or valves electronically, visible digitally at all times in the display on the test stand’s control panel. The test bench’s measured values are automatically transmitted to the server and a test report is created.

    This way, we guarantee the optimal function of your repaired hydraulic unit.

  • Is the test stand also suitable for larger components?

    Yes, our test bench is flexible and designed for all sizes of hydraulic components. Please contact us for specific inquiries.
