Test Bench

HTR 500 – multifunctional universal test bench

This unit is highly versatile and reliably and accurately tests hydraulic components, including:

  • Pumps and motors
  • Drives and valves
  • Hydraulic cylinders and accumulators
  • Hydraulic breakers
  • Pressure relief and pressure reducing valves
  • Flow control valves
  • Steering units and flow dividers
  • Ideal for fast, efficient and accurate functional testing in service and maintenance applications.

All brands and models of hydraulic components can be tested.
Component performance is determined by comparing the test results with the manufacturer’s specifications.

With the HTR 500, you can deliver your products to your customers with complete confidence.
