About AAH Apparatebau

AAH Apparatebau A. Hofheinz GmbH was founded in May 2000 by Arnold Hofheinz and manufactures centrifugal and immersion pumps, high-speed mixers and gear-driven agitators as well as containers and lifting stations at its Eggenstein-Leopoldshafen site. The focus is on small series and custom-made products built to customer-specific specifications, in particular for use with aggressive media. The agitators are constructed modularly and individually adapted to process engineering requirements; drives are supplied, among others, by SEW and KEB. Materials used include stainless steel V4A (1.4571), precision casting 1.4581, steel C 35 K (sheathed) as well as the plastics PPH, PVC and PVDF, with NBR and Viton as sealing materials. Customers come from the chemical industry, electroplating, water treatment, wastewater engineering, the paint and coatings industry, and environmental engineering. Every pump and every agitator is tested on the company's own test rig before delivery.
