In 2012, the American group Xylem Inc. acquires MJK. Xylem Inc. is one of the leading suppliers of water technology worldwide. The group is listed in New York, operational in more than 150 countries and in 2014, had an annual turnover of more than $ 4 billion.

Xylem Inc. owns over 45 different companies including Aanderaa, WTW, YSI, Sontek and Flygt. Today, MJK is thus associated with companies with a huge portfolio of diverse products within the water industries.

Business is not just a matter of money and profit. All companies have a deeper social responsibility. Like MJK, Xylem attaches great importance to making a difference, even in the smallest communities around the world. And we are very proud of that. Therefore, we also have clearly defined guidelines in relation to our own employees and business partners as well as transparency throughout our value chain.
