Körting Hannover

Körting Hannover AG (previously Körting Brothers AG) is a long-standing industrial engineering company in Hanover.

At the end of the 19th and beginning of the 20th century, the company played a leading role in the development of injector pumps in Germany and Europe.

Körting still produces pump and pump-based vacuum technology, but also industrial burners and machinery related to thermal and chemical purification/transformation processes


The Körting Brothers company was founded in Hanover on November 1, 1871 by the brothers Berthold and Ernst Körting. The brothers rented a small office a small space in the backyard of the present day 13 Joachimstrasse near Hanover Central Station. Berthold took charge of the commercial side, while Ernst specialized in the technical side. The brothers started successfully with the development and patenting of one of the first functioning injectors. In the beginning, only two workmen were employed.

Due to the ever increasing orders, in 1872 the company rented a factory on Celler street in what is now the Oststadt district. It consisted of two small buildings with a 12 horse-power steam engine. It would employ 41 workers. The young enterprise produced injectors and jet-pumps as well as the associated condensors. In 1874 the small factory was already supplying 2,000 devices.

The enterprise grew quickly, and in a few years established proxies in Germany and neighboring European lands (London, Paris, Milan, Genoa, Barcelona, Breslau (Wrocław), St. Petersburg, Vienna) and overseas (Philadelphia). The first foreign branch came into being as "Körthing Brothers" in Manchester. The American branch was opened in 1874. In 1880 the company had 20 staff and 170 workers. The product line was expanded to central heaters, gas scrubbers, gas-, gasoline-, and Diesel-motors. Körting vacuum brakes could be found in many trains of the time. In 1920, Körting also built the first Holzwarth-Gas Turbine.

In 1889, a new, larger factory with a large foundry and a powerhouse, would be erected in Linden, where the firm’s headquarters has been to this day. A workers’ town with a school was built in the direct vicinity, the so-called "Körtingsdorf". At its peak before the Great Depression, Körting employed approximately 1,700 workers and 400 staff. The company was one of the biggest employers in the Hanover region.

In 1904, the Fusch family entered the company through marriage. Today the Körting company is in the fifth generation of Körting/Fusch family ownership.

The product line was continually adjusted throughout the 20th century, whereby the core competence – flow devices (ejector pumps, nozzles, and industrial burners) – became ever more sophisticated. In contrast, the motor- and turbine-engineering declined and were ultimately abandoned.
