EDUR History
At the age of 25, Eduard Redlien founded the EDUR-Pumpenfabrik in a family house in Kiel on 01 April 1927. Eduard Redlien himself was both technical director and pump tester.
The EDUR base
A self-priming centrifugal pump developed in-house was the basis of the EDUR business model. In contrast to the side channel pumps already known back then, the EDUR-pump worked on the principle of the formation of a liquid-air mixture. It featured a sensationally high level of reliability and robustness for the time. The pumps were used to supply houses and farms, dairies and other commercial operations with water. With these self-priming pumps, the young company grew steadily throughout the 1930s and expanded its circle of customers to abroad as well.
The growth of EDUR
All research work was stopped at the beginning of World War II, but production of EDUR-pumps continued against much resistance and under the most adverse circumstances.
EDUR was able to overcome the obstacle of the German currency reform on 19 June 1948 with the support of the Dutch partner Van Wijk & Boerma. The delivery of a railway carriage with about 300 pumps was scheduled to be already paid for in the new Deutschmark currency.
All functions of the company were located in the Hamburger Chaussee in the city of Kiel until the early 1950s. After the acquisition of the Wulfsbrook site in 1953, new production workshops were successively built in 1954.
A crucial event in the history of EDUR was the premature and sudden passing of Eduard Redlien on 13 April 1959. His wife Irma Redlien took over the management of the company, strongly supported by the loyal employees.
The hot summer of 1959 started early and turned out to be a saving grace for the company. The farming industry desperately needed pumps for the irrigation of fields.
During the 1980s the necessity of a reorientation became more and more evident. The company changed its focus, away from series production to a customer-oriented niche supplier. A new generation took over and the new management quickly implemented the required measures.
And today?
Due to the modular design, there are almost no limits on the pump configuration. Shaft seals range from a single-acting mechanical seal to double-acting sealing systems to the magnetic coupling.
The material range comprises grey cast iron version, for example for water and coolants, bronze for sea water, stainless steels for process engineering and special steels such as duplex steel and Hastelloy for oil and gas. Different pump hydraulics enable gas-loaded liquid conveyance, enrichment of liquids with gases and low NPSH values.
