About SIMPEX Hydraulik
SIMPEX Hydraulik Gruppe is a medium-sized service and manufacturing company for hydraulics, pneumatics and central lubrication technology. Its portfolio includes manufacturer-independent repair and overhaul of hydraulic cylinders, pumps, motors, valves and power units, power unit and plant engineering including pipework and commissioning, the manufacture of large and special cylinders with unit weights of up to 25 tonnes, as well as valve control systems in switchgear cabinet, table and column designs. This is complemented by systems engineering with CAD design, electrical engineering/automation, central lubrication, plant modernization, test bench and testing technology, as well as refractory technology for steelworks. As a specialist wholesaler with numerous manufacturer representations — in partnership with Bosch Rexroth since 1994 — SIMPEX also supplies spare parts. Key customers come from open-cast mining, power plant technology, steel production and plant engineering. The group operates 15 locations, branch offices and service centers throughout Germany, including directly at the open-cast mines and power plants of the Lusatia region, with a production facility in Eisenhüttenstadt and headquarters in Leipzig.
