Desmi, formerly De Smithske Jernstøberier og Maskinværksteder (English The Smith Iron Foundries and Machine Workshops), is a manufacturer of pump systems and clean-up solutions based in Nørresundby, Denmark.
The company was established by master goldsmith and ship-owner Henning Smith (1694–1856).
On 21 December 1833, he was granted a royal license to establish an iron foundry in Aalborg. The iron foundry was established the following year.[1] On 10 April 1843, it acquired its first steam engine.[2] Smith's widow sold the company after her husband's death in 1856. On 1 January 1857, it changed its name to I/S Det Smithske Jernstøberi og Maskinværksted (The Smith Iron Foundry and Machine Workshop). On 26 February 1875, it was converted into a limited company (aktieselskab) as A/S De Smithske Jernstøberier og Maskinværksteder (The Smith Iron Foundries and Machine Workshops). On 12 July 1878, it delivered its first complete pump system. In 1897, it started its production of church bells.
In 1937, De Smithske Jernstøberier og Maskinværksteder relocated from its old sites at Algade and Papegøjehaven to larger premises at Vestre Fjordvej/Annebergvej. The iron foundry was closed in 1977. The remainder of the company was moved to Lindholm the same year. In 2003 the name of the company was changed to De Smithske. In 2005, it was changed to Desmi.[2]
The present company specialises in the production of pump systems and clean-up solutions for harbours and rivers.
