We, the GRIBI Hydraulics AG, developed on the basis of the most recent knowledge a corrosion-resisting hydraulic cylinder meeting highest requirements. As raw materials only Cr-Ni-Mo-steels are used which have a very high resistance against crevice and pit corrosion as well as intercrystalline corrosion. This hydraulic cylinder has been designed to cover applications in the field of sewage and water treatment plants, environment technology, agriculture, offshore plants, chemical-technical industry and food processing.
