In 1905 The Nash Engineering Company was founded in Norwalk, Connecticut, USA as a manufacturer of liquid ring vacuum pumps. During the early years, NASH developed vacuum stream heating systems and vacuum sewage collection systems for many of the growing USA cities. NASH also developed vacuum pumps which were applied in the manufacture of pulp and paper. During the mid-20th century, NASH continued expanding into industrial markets such as paper, power, petrochemical, general industrial and food markets.
In the early 1960's Nash discontinued sales for commercial markets-vacuum heating and sewage collection-to concentrate on the industrial markets. Constant growth continued up to the U.S. recession in 1982. During that time, NASH increased their investment in research and development rather than cutting back as many U.S. companies had done. As a result, our sales since 1984 have been growing with the introduction of new products with superior features and benefits in the areas of efficiency, reduced water consumption, serviceability, quality, and much more.
In Europe, Siemens-Schuckert applied for the liquid ring patent in 1903 and started manufacturing liquid ring pumps as well. Under the "elmo" brand name, liquid ring pumps made by Siemens achieved an excellent reputation and became well known in many industries and applications. Siemens spun off the liquid ring pumps and compressor business in 2000 and founded elmo vacuum technology.
In 2002, Nash Engineering merged with elmo vacuum technology to become nash_elmo. A 2004 acquisition by Gardner Denver Inc. resulted in a division known as Gardner Denver Nash.
In 2012, Nash opened a new Divisional Headquarters and North American Operations Facility in Bentleyville, Pennsylvania.
For over a century, through many changes, our experience has always dramatized how much value we can offer to our customers beyond furnishing good vacuum pumps. It's a kind of value that yields continuing rewards.
