About AS Strömungstechnik
AS Strömungstechnik GmbH is a family-owned company based in Ostfildern near Stuttgart, specializing in safe dispensing and filling systems for liquid chemicals. The portfolio includes the QC system with dispensing and filling heads, custom-made dip tubes, quick couplings, diaphragm pumps, robotic systems for fully automatic container filling, as well as fittings, valves and hoses for chemical plant engineering. Production is carried out mainly from high-purity high-performance plastics such as PFA and PTFE, and in part from stainless steel, using in-house CNC machines and injection molding machines – from prototypes and small series to large volumes. Founded in 1987 as a manufacturer of high-tech pumps for drum emptying, AS today serves around 4,500 customers in industries such as semiconductors, chemicals, pharmaceuticals, solar/PV and water treatment, including BASF, Bosch, Merck, Brenntag and Infineon. With around 100 employees, a US subsidiary in Pennsylvania and a sales partner in Singapore, the export share is over 60 percent.
