Custom manufacturing for the steel and heavy industry

HPT Hydraulik- und Pneumatik-Technik GmbH develops and manufactures hydraulic and pneumatic cylinders in standard, special and one-off designs as well as rotary and swivel feed-throughs for liquid and gaseous media in the low- and high-pressure range up to PN 40. In addition, the company repairs cylinders and rotary feed-throughs of its own and third-party makes, including the reconstruction of components that are no longer available. Manufacturing follows the Engineered to Order principle: load case, stroke, medium, temperature and installation space are designed on a project-specific basis. Customers are plant manufacturers, OEMs and operators in steel and ironworks, the metal industry and special machinery engineering; via OEM partners, HPT components are in use at steel producers worldwide. Development, manufacturing and assembly take place at the site in Mülheim's harbor, Lahnstraße 41 in Mülheim an der Ruhr. The company is owner-managed by Ingo and Bernd Gocke and certified to ISO 9001:2015.
