Grun-pumpen Gmbh

What Grun-pumpen Gmbh does

grün-pumpen GmbH is a German industrial manufacturer specializing in drum pumps and progressive cavity pumps designed to transfer, fill, and dose liquids from drums, IBC containers, and other vessels. Founded in 1993 by Herbert Grün and headquartered in Alzenau, the company develops modular pumping systems built from configurable pump units (polypropylene, PVDF, stainless steel, aluminum) and interchangeable motors, with proprietary features including ATEX-certified explosion-proof variants, a quick-change SWK coupling system, three-stage radial pumping stations, and high-viscosity progressive cavity pumps rated up to 250,000 mPas. The product range covers flow rates from 8 to 40+ l/min, immersion depths up to 1,200 mm, and delivery heads up to 12 meters, with a 2024 addition of the scorpio battery-powered motor compatible with the Makita battery system. The company serves ten industrial verticals including chemical, pharmaceutical, food & beverage, cosmetics, paints & coatings, petrochemical, agriculture, surface technology, general industry, and water & wastewater treatment.

The business model is a sales-led industrial OEM model: revenue is generated primarily through one-time hardware sales of pumps, motors, complete pump sets, accessories, and spare parts, with pricing provided on a contact/quote basis for custom configurations. In Germany, sales are run through regional representatives; internationally, the company is distributed through over 35 authorized partners spanning Europe, the Middle East, Asia, and South America. Marketing is anchored by trade show participation at ACHEMA, FACHPACK, European Coatings Show, and PUMPS & VALVES, complemented by downloadable technical documentation and a newsletter. The company was acquired by WP-ARO GmbH in autumn 2019, relocated to its current 3,000 m² Alzenau facility in 2019, and became part of the FourFluid Group in February 2025 alongside three other specialized pump technology companies.
