In the 1950’s, the company’s founder Wilhelm Düchting owned and operated “Repair Shops Wilhelm Düchting”-where he and his colleagues repaired pumps from neighboring industries, predominantly mining. They quickly developed a specialty in the repair of dewatering pumps from neighboring mines, which resulted in Wilhelm Düchting deciding to begin the construction of a new pump factory which would focus on the manufacturing of high pressure, mine dewatering pumps.
With the knowledge and experience gained from their pump repairs, they quickly developed their own pump series only a few years after opening the pump factory. This first high-pressure pump series, the HK 10, rapidly spread and even to this day is the dewatering pump of choice for mines in the Rhine and Ruhr areas of Germany. At its peak, the German coal industry had approximately 1,000 DÜCHTING HK pumps in operation.
The series expanded in the 1960’s with the achievement of the HK 200 series, resulting in the ability to lift water from depths of up to 1200 meters with a single pump. With this capability, main drainage was born in the German mining industry.
In the following years, DÜCHTING PUMPEN increasingly focused on developing more wear-resistant, single stage pumps with its first significant success in 1963 with the largest ever built dual flow water pump series PK 60.
Under the management of the founder’s son Dr. -Ing Wolfgang Düchting, a new series of wear resistant pumps were developed in 1978 for the treatment of coal. Of these series, the DH tank pump series provided the greatest wear resistance.
Due to the beginning of new environmental measures related to desulfurization and gas-gleaning of fossil-fired power plants and industrial facilities in 1986, a major boom and market need was developed for a new single-stage, highly wear resistant pump from the DÜCHTING line.
As a result, in the beginning of the 1990’s DÜCHTING PUMPEN developed a new non-metallic material that exhibited extreme resistance to wear and corrosion, particularly in relation to gas-cleaning applications. The development of this mineral cast material technology, which consists of silicon carbide particles bonded with an epoxy resin, mainly focused around the innovation and discovery of the optimum particle size distribution of the silicon carbide particles to optimize the material’s bonding strength.
For the production and processing of the SiC mineral-cast material, SICcast Mineralguß GmbH & Co. KG was founded in 1996. DÜCHTING PUMPEN had large initial successes with this SICcast material, specifically in gas cleaning applications in waste incineration plants in which the corrosion-specific attributes of the process are significantly challenging for high-alloy stainless steels. For problematic corrosive and abrasive applications, the new SICcast material became an ideal alternative for expensive metallic materials, standard ceramic materials, and highly abrasive plastics.
By the late 1990’s, DÜCHTING PUMPEN began replacing steel pumps utilized in Flue Gas Desulfurization with a SICcast alternative, with initial installments taking place in foreign installations. Since the early 2000’s, SICcast single-stage pumps have been utilized for all new domestic FGD installations, with installations continuing to grow domestically and internationally.
Parallel to the discovery of single stage SICcast pumps in the 1990’s, there were also additional developments taking place in the DÜCHTING group regarding the high-pressure pumping sector.
The series of high pressure DÜCHTING pumps were expanded and refined, resulting in additional applications such as membrane feed pumps in desalination plants and booster pumps in pressure exchanger programs. Innovations in these series focused on requirements regarding energy efficiency and optimization. The most recent innovations and developments in these fields can be seen in both the DÜCHTING high pressure and single stage SICcast pump series.
In 1998 an additional company was added to the DÜCHTING group with the incorporation of “DÜCHTING Walzen Service” which caters to paper mills providing rollers and other accessories.
DÜCHTING firmly understands and believes in the significance of a pumping system as a single component in the overall process of an industrial facility. Our focus on the success of our pumping system and our customers has and will continue to be one of our biggest advantages as a company!
Today, under the Managing Director Dr.-Ing Carsten Düchting, DÜCHTING PUMPEN focuses on the worldwide marketing of products by both DÜCHTING PUMPEN and SICcast. This marketing is achieved through its partners located around the world, and through its own office branches in North America, South America, Russia, South Africa, and Kazakhstan. Further strategies are continually being developed to increase this marketing effort and to provide products and services to new challenging applications worldwide.
