Grundfos (Danish pronunciation: [ˈkʁɔnfʌs]) is the largest pump manufacturer in the world, based in Denmark, with more than 19,000 employees globally.

Grundfos was established in 1945 in Bjerringbro by the late Poul Due Jensen in the cellar of his home.

[3] Grundfos circulator pumps are used for heating, ventilation and air-conditioning in many applications, including private homes, office buildings, and hotels.

In industry, circulator pumps are used in processes, plant maintenance, and as built-in parts in Original Equipment Manufacturer (OEM) products.

The center is used for research into new materials, development of process technology, and construction of advanced production equipment and machines.

In 1993, development, design and product management moved into a newly built "innovation centre".

[9] Grundfos is a long-standing Official Partner of the EHF EURO handball Men's[10] and Women's[11] teams.
