In 1956, brothers Bela and Hermann Deutsch were approached to machine a small venturi for a local St. Louis business that desired an automated process to inject dish soap into a sink. Fast forward to today, DEMA is a global leader in the institutional cleaning and fluid control markets. Embracing our heritage, DEMA is still owned by the Deutsch family, with active 3rd and 4th generation family members, but far outnumbered by our over 420 global team members.
