simpex hydraulik


The companies of SIMPEX HYDRAULIK are specialised on developing, manufacturing and commissioning hydraulic plants and aggregates. In the field of centralised lubrication technology, our activities in the modernisation of old plants and for new buildings are much sought-after.

With a 40 year track record, another core competency of our group of enterprises is brand- and manufacturer-independent repair and overhaul of hydraulic components of all kinds.

We are your qualified partner – also when it comes to the most complex problems of fluid technology and tribology.


Our developers and designers, software engineers and project managers use the latest networked CADtechnology to develop efficient solutions in hydraulics, pneumatics and centralised lubrication technology as well as in electric control engineering for various applications for our demanding customers.

In our business unit “Systems Engineering“, we manufacture aggregates in all sizes. Aligned with the operating processes of our customers, performance and control of the aggregate are individually adjusted. As a matter of course, we also manufacture the required valve controls as well as customer-specific special cylinders up to a unit weight of 25 tons in order to achieve the maximum degree of efficiency.

For more than forty 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.
