History

Managing Director
Carsten Pump
INDAG Maschinenbau GmbH was founded by Martin Willuhn in 1953.
It all began with the internal gear displacement pump developed by Martin Willuhn for conveying viscous media. Pumps and flow mixers were manufactured specifically for the food and chemical industries. A decisive step towards expansion was taken with the development of individual pumps and mixers into complete systems, which were known under the protected brand name FlowMix®. In 2001, the company moved into a new building with production and office space. From 1991 to 2025, under the leadership of owner Dipl.-Ing. Wilko Willuhn, son of Martin Willuhn, the company increasingly specialised in the manufacture of dynamic inline mixers. Carsten Pump has been the new managing director of INDAG since July 2025.
With more than 70 years of experience, INDAG is a specialist in the field of liquid mixing.
