RP Witten, Germany in the 1950s

Ruhrpumpen GmbH in the 1950s

The company’s history officially began in 1950 in the neighborhood of Annen in Witten, Germany under the name of Ruhrpumpen GmbH Wende & Hentschel. It started operations in the empty halls of the former Annen steel factory and, after the Second World War, it got busy with the maintenance of the existing installed pumps from all makers and models, as well as the manufacturing of new spare parts. Very quickly, a series of new constructions generated the need for new pumping equipment, primarily centrifugal and piston pumps for the ship industry, and, a little later, centrifugal pumps for pipelines and refineries. This gave birth to Ruhrpumpen’s extensive pump portfolio and started a series of changes for Ruhrpumpen:

  • 1955 Ruhrpumpen GmbH was acquired by Ruhrstahlwerke AG and continued operating under the same brand.
  • 1957 Ruhrpumpen started the production of process pumps under the license of PACIFIC San Francisco, bringing a continued development of the company.
  • 1963 the Rheinstahl Hüttenwerke AG acquired Ruhrpumpen GmbH.
  • 1974 the jumbo merger of the Rheinstahl AG and the Thyssen AG took place and Ruhrpumpen became part of the Thyssen Industrie AG machine engineering until 1996, when the Thyssen managing board decided to withdraw from the pump business. The Ruhrpumpen era was about to end.

Corporacion EG was a successful company with strong reputation for quality and operational excellence that began operations in 1979 as a Computer Numeric Control (CNC) machine shop in Monterrey, Mexico, to render services to Original Equipment Manufacturers (OEMs). In 1986, the firm acquired its first pump company, Crane Deming de Mexico SA de CV, and went on to take over Worthington de Mexico SA de CV in 1991.

Since 1997, a series of capital investments, acquisitions, new product development and a strong focus on customer needs have taken Ruhrpumpen to become a global supplier of highly engineered pumping technologies and related products:


Ruhrpumpen plant in Tulsa, OK, USA

Acquisition of the Flowserve manufacturing plant in Tulsa, OK, and formation of Ruhrpumpen USA. By acquiring this facility, RP gained access to the world’s biggest market and obtained an exclusive license to manufacture eight product lines typically used in oil refineries and power generation plants. This acquisition also established the foundations for the new Ruhrpumpen Group.

Ruhrpumpen Worthington de México became Ruhrpumpen S.A. This marked the beginning of what today is the Ruhrpumpen Group.



Our 1st complete decoking system for a refinery was quoted for Venezuela and won the order for Hamaca Project. At the time, we had no experience in decoking systems neither drawings, with a strong German Engineering team the engineering and design process started. In the end, Ruhrpumpen successfully supplied the system series 001. Today we are a major player in the global decoking business, leading on technology and performance.
