    In 1950, the cleaning technology division was established with the development of the first European hot water high-pressure cleaner, the DS 350. [11] From the mid-1950s to the 1970s, the production of steam generators for industry and construction was a key focus for the company, while cleaning technology only later became Kärcher's main revenue-generating sector.

    Most high-pressure pumps at this time, though, operated around 500–800 psi (3.4–5.5 MPa). High-pressure systems were further shaped by the aviation, automotive, and oil industries. Aircraft manufacturers such as Boeing developed seals for hydraulically boosted control systems in the 1940s, [ 14 ] while automotive designers followed similar ...
