In 1871, Ernst Körting invented the steam jet injector as a boiler feed pump and founded the company Gebrüder Körting in Hanover with his brother Berthold. Today Körting Hannover GmbH has subsidiaries in Brazil, China, India, Malaysia and Poland, and ranks as a leading manufacturer in the development and production of application-specific jet pumps, vacuum engineering products and environmental technology.

The company manufactures its demanding components on CNC machine tools from DMG Mori, among others. They include a DMU 125 FD duoBLOCK installed in 2006, which has been made fit for at least another 10 years thanks to a general overhaul completed in 2022. Jet pump ejectors for wastewater treatment application are made of polypropylene and have been produced this machine since its arrival. In 2021 Körting considered investing in a new machining centre.

“However, the DMU 125 FD duoBLOCK was technically suited to our requirements, so we decided to commission DMG Mori Used Machines to overhaul our existing model,” explains plant manager Jürgen Sack, who outlines some of the many benefits. “Firstly, we would have had to invest at least twice as much for a new model. Secondly, the overhaul did not require any changes on the shop floor and we were able to continue using our existing tools and equipment, such a fixtures and NC programs. Thanks to the manufacturer’s more modern, high quality parts, the accuracy of the machine is also improved. What’s more, we benefit from a six-month warranty and 10-year availability of spare parts and service.”
