About Jahns-Regulatoren
Jahns-Regulatoren GmbH is a family-owned machinery manufacturer based in Offenbach am Main that has been in existence since 1905. The company manufactures slow-running radial piston motors, axial piston pumps, governors as well as flow and volume dividers for hydraulics and drive technology. Following the acquisition of the product lines of the company ABG from Karlsruhe in 2000, it also manufactures centrifugal pumps, submersible pumps and agitators, which are used mainly in the chemical and process engineering industries. Production takes place on CNC machines in small lot sizes with a high depth of manufacturing at the Offenbach site. Product developments are advanced jointly with customers; in addition, the range includes the purchase and distribution of traded goods from hydraulics and drive technology as well as the design and selection of agitators and pumps.
