To expand our product range, we have added customer-specific hydropulsers for generating highly dynamic linear movements to our product range, similar to our torsional oscillators in the HSH swivel motor series.

Based on decades of experience in the construction of swivel motors with hydrostatically mounted output shafts, the hydraulic cylinders in the HZH series also have a hydrostatically mounted piston rod.

In conjunction with highly dynamic control valves and position measuring systems, the cylinders are preferably used in controlled systems in which high-precision forces and movement patterns have to be generated.

Due to the lack of internal seals, disturbance variables such as internal friction and the stick-slip effect are reduced to a minimum. At the same time, they are suitable for test series with large numbers of load cycles where an interruption, e.g. due to the replacement of internal seals, is not permitted.

With the combination of cylinders from the HZH series and swivel motors from the HSH series, Hense Systemtechnik provides the market with high-precision drive axes for reliable and economical tension/torsion testing systems.
