Company History
What we make has been making industries better since 1865.
The history of Marsh Bellofram provides a look into the history of American manufacturing in the 20th century, and how it adapted to prepare for the needs and challenges of the 21st and beyond. It’s a story of smaller companies coming together to combine strengths, vertically integrate where it made sense, be strategic in their growth, and better serve a similar customer base.

Marsh and Bellofram were sister companies of the Desco Corporation. They were combined into Marsh Bellofram in January 1995.
Prior to that, Bellofram was originally established in the Boston, Massachusetts, area in 1953 to manufacture elastomeric rolling diaphragms. John Taplin, the founder and original owner of Bellofram, designed air cylinders, air regulators, gauge protectors (diaphragm seals), and other pneumatic and hydraulic devices using his diaphragms. In the early 1980s, Rexnord purchased Bellofram, and then in 1986 sold Bellofram to the Desco Corporation of Columbus, Ohio.
Desco moved Bellofram from its plants in Pelham, New Hampshire, and Burlington, Massachusetts, to the Newell, West Virginia, facility — designed, constructed, and fully integrated specifically for the high-volume, high-precision manufacture of elastomer products.
Meanwhile, the instrumentation arm of the company was originally established in 1865 in Skokie, Illinois, as the James P. Marsh Company. Marsh was acquired in 1988 by Desco and relocated to Hastings, Nebraska, to share operations with Desco’s Marshalltown Instruments. Marshalltown had been founded in 1918 in Marshalltown, Iowa.
Since Marsh Bellofram became one entity in the 1990s, it has continued to grow with strategic acquisitions that play to its core strengths of process, automation, measurement, and control. It is built for continued growth through the highest product quality standards, critical manufacturing capabilities, innovative engineering, and an unparalleled dedication to customer service and support.
