In 1905 The Nash Engineering Company was founded by Lewis H. Nash 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.
