In 1960 Prof Dr h. c. Viktor Dulger (external link) founded Chemie & Filter GmbH in Heidelberg. With the invention of the first electronically controlled die-cast metering pump, he laid the foundation for his life's work. The metering pump, named ‘ProMinent’, gave the entire company its name, ProMinent GmbH (external link), which is still used today.
Today, the company (external link) specialises in water treatment and fluid dosing technology. The company is present in over 100 countries and is still family-owned today.
Viktor Dulger († 2016) and his wife Sigrid Dulger († 2023) established the Viktor & Sigrid Dulger Foundation in 1995. The foundation promotes young scientists. The foundation is also committed to arts and culture.
