Busch Vacuum Pumps and Systems Acquires NSB Gas Processing

Busch Vacuum Pumps and Systems is pleased to announce that the swiss-based engineering company NSB Gas Processing is now part of the global Busch group. The NSB Gas Processing business has been renamed Busch NSB AG and brings a highly regarded team of engineers and a portfolio of liquid ring vacuum pumps, compressors and systems to the Busch group.  

NSB has a heritage dating back to 1844 and will continue to provide the same very high standard of liquid ring vacuum pumps, compressors, and vacuum and compressor systems for industry. With the acquisition of NSB, the Busch group can now offer reliable vacuum and overpressure solutions for heavy-duty conditions in the oil and gas industries and chemical and pharmaceutical sectors. One of the strengths of the Busch NSB product portfolio is in flare gas recovery, a sub-sector of the oil and gas industry. Flare gas recovery offers the advantages of more-efficient use of scarce resources and a reduced environmental footprint.

NSB products which customers have relied on over the years are now offered under the new brand Busch NSB and will continue to meet the industry requirements for quality based on state-of-the-art technology. Furthermore, NSB customers are now set to enjoy the advantages of the worldwide presence of Busch with the largest and most extensive global service network – in more than 40 countries worldwide.

NSB customers will now also profit from the experience and expertise of Busch in liquid ring technology. The world-class Dolphin series of liquid ring vacuum pumps and compressors are used in a variety of industries worldwide. This series is now complemented by liquid ring vacuum pumps, compressors and systems available under the new brand Busch NSB. This means a greater choice from a wide range of liquid ring technology to meet customers’ requirements.

“With NSB, Busch is able to offer more solutions and a more rounded portfolio, while integrating their expert knowledge for our customers,” explains Sami Busch. “Flare gas recovery is a technology with a significant environmental impact. Customers of NSB are now set to profit from our service expertise and ability to provide spare parts and service 24/7 – wherever they are. And NSB as part of the Busch Group can look forward to a new impetus for future growth.”

Busch Vacuum Pumps and Systems was founded by Dr.-Ing. Karl Busch and his wife Ayhan Busch in 1963. Dr.-Ing. Karl Busch developed the “Huckepack”, which was the first vacuum pump that could be used for vacuum packaging of foodstuffs. The follow-up product, the compact “R 5” rotary vane vacuum pump, revolutionized food packaging. A further milestone represented the development of the “COBRA” screw vacuum pump. In 1971 the international expansion of the Busch group started with the founding of a sales company in the UK. The first production plant outside Germany was established in the USA in 1979.
