About us

Johnson-Fluiten was founded in 2003 as a joint venture between Kadant Johnson and Fluiten Spa and to understand its identity, it is essential to know the two companies that shaped it:

Kadant Johnson or more precisely, the historic company named The Johnson Corporation was founded in the United States in 1933 and was the pioneer company in the invention of the rotary pressure joint. Over the years, the company has grown to become a world leader in the production of steam rotary joints. In 2005, the company was acquired by the multinational Kadant Inc and renamed as Kadant Johnson.

Fluiten Spa, is a historic Italian company that is a benchmark in the precision engineering sector. Fluiten Spa designs and manufactures standard and customised mechanical seals according to its customers' specific requirements. The company's flagship is the R&D Department, equipped with a state-of-the-art dynamic test room in Europe, one of the few suitable for complex test calculations and operating simulations under the worst operating conditions.


Johnson-Fluiten is the perfect combination of the two, and benefits from the best features of both companies.


- on the one side the structure of KADANT, who, thanks to its several locations around the world, can reach customers worldwide and provide a sales network and highly qualified support available almost everywhere, with the guarantees, controls and procedures that are typical of a multi-national company.
