SPX Corporation is a Fortune 500 multi-industry manufacturing firm. SPX's business segments serve developing and emerging end markets, such as global infrastructure, process equipment, and diagnostic tool industries.[1] With corporate headquarters in Charlotte, North Carolina, they have operations in more than 35 countries around the world. Their products include pumps, valves, and other fluid handling devices; diagnostic tools, fare-collection, and cable/pipe locators; cooling, heating, and ventilation equipment; and compactors, power systems, broadcast antenna systems, dairy dryers, aerospace components, and pressure vessel closures.

SPX was founded in 1911 in Muskegon, Michigan as the Piston Ring Company.[3]
The company designed and manufactured original equipment components for Detroit’s largest car companies, and quickly earned a reputation for quality products serving the rapidly developing automobile industry.

After acquiring Accuralite Company in 1931, the company changed its name to "Sealed Power Corporation" and also started manufacturing piston rings, pistons and cylinder sleeves for various military applications. By the 1950s, the company had distributors in every state and in more than 40 countries. At the time, Sealed Power products were used as original equipment in more than 80 percent of American-made cars and trucks.

By 1988, and after a number of strategic acquisitions to further diversify the company into a replacement parts and specialty service tool manufacturer, the company changed its name to SPX Corporation. For the next 10 years, they remained a U.S.-centric automotive component manufacturer with nearly $1 billion in sales.

In 1998, a series of additional acquisitions and focused organic growth helped SPX diversify even further into flow technologies and thermal equipment and services.

Today, SPX is a global multi-industry manufacturing leader and supplier of engineered technologies that support the critical needs of modern societies, with a concentration in power and energy and food and beverage markets. With more than $5 billion in annual revenue, SPX has operations in more than 35 countries and employs more than 15,000 employees worldwide.
