About DÜCHTING PUMPEN
DÜCHTING PUMPEN Maschinenfabrik GmbH & Co KG is a family-owned company founded in 1938, now in its third generation of family ownership and headquartered in Witten in the Ruhr region. The company develops, manufactures, tests and installs single- and multi-stage centrifugal pumps made of metallic and non-metallic materials. Key focuses are high-pressure centrifugal pumps for seawater desalination via reverse osmosis, pumps for flue gas desulfurization (FGD) in power plants, wear-resistant pumps for mining, and corrosion-resistant pumps for the chemical and pigment industries. A central product feature is the company's proprietary material SICcast, a mineral-cast-like, metal-free SiC casting that in the wetted area exceeds even nickel alloys in corrosion resistance. In addition to new pumps, the company offers original spare parts with worldwide 24-hour delivery, retrofit, commissioning, testing (Try & Buy) as well as consulting on life-cycle costs and energy recovery. Around 120 employees work in development, production and international service for customers worldwide.

Materials & Pump Types
SICcast (SiC Mineral Cast)
Metal-free mineral cast for all media-wetted parts with high corrosion and wear resistance, e.g. in FGD and chemical pumps.
Metallic Materials
Various metals for high-pressure and wear pumps such as the HPH, HPE, WRX and HPX series.
Flue Gas Desulfurization (FGD)
Field of application of the MC, MCC and WRV pumps in power plants, sometimes in large quantities per plant.
High-Pressure Reverse Osmosis
High-pressure centrifugal pumps up to 250 bar with energy recovery units for seawater desalination.
Mine and Processing Pumps
Wear-resistant centrifugal pumps for high-pressure mine dewatering and coal processing.
