Repair and overhauling
strich_klein_grau

aufzaehlung For more than thirty years, brand-independent repair and overhauling
of hydraulic parts has been a core competency of SIMPEX HYDRAULIK.
Apart from repairing established manufacturer-components, we
particularly specialise in overhauling old series of well-known
manufacturers which are no longer being produced.

Working for you, we always start with a detailed assessment of any given
damage. In this process, we actively advise you concerning the extent of
repair to be expected and the tasks which need to be done by our
specialists. We also keep the cost-effectiveness of the measures
planned in comparison to purchasing or building new parts in mind for you.

For all hydraulic components repaired by our experts, we guarantee
reliability and functionality on the level of a new product. Every stage of
repair is documented. The results of our work are logged for our
customers at the test stands.
