Our History: Facts & Figures

In the 1950s, the founder of DUCHTING PUMPEN, Wilhelm Düchting, started in the pump-maintenance business by looking after pumps that were installed in the heavily-industrialised Ruhr-Area. It soon became clear that the focus of his work was to be the maintenance of pumps that were installed in the numerous coal mines. The know-how gained from these maintenance activities soon enabled Wilhelm Düchting to construct and build his own pumps: The first series that was produced in his plant was called HK10, and it did not take long until this series became widely used. Even today, this pump series has remained the most frequently-employed pump for main and secondary mine draining in the Rhine-Ruhr Area. During the heyday of the German mining industry, there were as many as 1,000 DUCHTING PUMPEN HK 10 pumps
installed in local coal mines.

The HK series was further enhanced in the 60s. Its top model, the huge HK 200, even made it possible to pump mine water from depths of up to 1,200 metres in one go to the surface. Thus, DUCHTING PUMPEN offered a complete and sophisticated solution for main and secondary mine drainage.

In the following years, DUCHTING PUMPEN put a lot of time and effort in developing wear-resistant, single-stage centrifugal pumps. By 1963, the company made its first major breakthrough in this field by installing a PK 60 in the Lohberg coal mine, a wash water pump that was by far the biggest one of its kind at the time.

Besides the pump business, DUCHTING PUMPEN also set-up a roll department that satisfied the demand of local paper mills for rolls and their fittings. Several years later, in 1998, the present company director, Wolfgang Düchting, hived off this department to become a subsidiary of DUCHTING PUMPEN by the name
                                                 of DUCHTING WALZEN Service.

As a result of the changing economical situation in the Ruhr Area and after the founder's son and current manager, Wolfgang DUCHTING had joined the company in 1978, several new series of wear-resistant pumps for the processing of coal have been developed and successfully introduced to the global market. Following the environmental measures with respect to coal-heated power plants that have been implemented in Germany and Europe over the past decades, similar pumps were built for flue gas desulphurization; these, too, were successfully marketed and shipped to locations throughout the world.


During the early 90s, DUCHTING PUMPEN developed a new, highly wear- and corrosion-resistant, non-metallic material. SiC-mineral cast, as it was called, consists of mineral materials such as silicon carbide or quartz which are mixed
in a vacuum with epoxy or vinyl ester resins as the bonding agent and then cast into suitable moulds. In 1996, another subsidiary of DUCHTING PUMPEN,
namely SICcast GmbH & Co. KG, was founded in order to produce and market this promising new material. As could have been expected, SiC-mineral cast
has since been successfully employed on a global scale for an ever increasing number of applications, among others, for example with respect to pumps
used for flue gas desulphurization in waste incineration plants. Another field of application for SiC-mineral cast can be found in the chemical industry, especically in corrosive and abrasive (and thus rather problematic) processes, where this new material has meanwhile begun to replace expensive metallic materials and sintered ceramics or wear-resistant plastics.

Recently, DUCHTING PUMPEN has begun to work on yet anyother important new application: In the field of seawater desalination, for instance for drinking water purification, highly-specialised pumps are required that meet particularly high demands with respect to energy optimisation and availability. The development of these new pumps at DUCHTING PUMPEN is backed-up on a scientific level through co-operations with renowned institutions. DUCHTING PUMPEN has also realised that, for being successful in this field, it is of utmost importance to understand and optimise the complex processes that are connected to reverse osmosis.
