About us – Your partner for hydraulics and pneumatics
Hydraulik-Technik Gülich-Pohl GmbH is a family-run company in its third generation, founded in Kerpen in 1964, and has been a partner for hydraulics and pneumatics for over 60 years. The team of around 40 employees – fitters, industrial mechanics and engineers – repairs hydraulic and pneumatic cylinders, pumps, motors, valves, power units, gearboxes, Hägglunds drives and accumulators. Since 1970, the company has designed and manufactured hydraulic cylinders and power units of its own brand Hydros to drawing or sample; materials include high-strength steels, stainless materials and special alloys, optionally with its own HTec coating. The range of services includes on-site fault diagnosis, fluid service and oil analysis, hose service, hydraulic piping, accumulator service, loaner power units as well as the modification of existing hydraulic systems. As a service and trade representative of Bosch Rexroth, HT also operates an online shop with over 220,000 items. Customers come from industries such as open-pit mining, mining, chemicals, the paper industry, wind energy, aerospace engineering, mobile machinery and plant/special machinery engineering; deliveries are made worldwide.
