Union Pump, founded in 1884 in Michigan, USA, began in the basement of Adams & Smith, a wagon and blacksmith shop. A.E. Preston, John Heyser, Edward Keet, and James Gridley started a small machine shop there, manufacturing woodworking and ironworking machinery.

The company was incorporated on May 22, 1885, when D.W. Lovell joined the founders. By 1892, the company began manufacturing pumps and moved to 87 Capital Ave., S.W. in 1893. The name changed to Union Steam Pump Co. in 1894, and by then, it was fully engaged in manufacturing steam pumps.

Leadership and World War II Contribution

Earl P. Ordway joined the company as an engineer in 1907 and was elected president in 1938. His son, Philip, joined the business in 1939. During World War II, the company employed over 700 people, producing pumps for the Navy. In 1959, the company dropped “Steam” from its name, becoming Union Pump Co. Renowned for manufacturing steam pumps and engines for trains and maritime vessels, the company played a significant role in supplying equipment for various applications, including U.S. government orders during World War II, as meticulously documented in historical logbooks.

Relocation and Ownership Evolution

In 1987, the manufacturing facility had relocated to a purpose-built site in an industrial park, following a strategic move encouraged by the city of Battle Creek. This facility featured an optimized layout for efficient service operations.

In 1997, the company was purchased by Textron and merged with the David Brown Pumps Division. Initially focused on reciprocating pumps, Union Pump expanded to include a wide range of centrifugal pumps, becoming known for its engineering expertise and innovative solutions. The company underwent further changes in ownership, in 2008, Union Pump merged with Clyde Pumps to form ClydeUnion Pumps, combining their extensive histories and product lines. Each transition brought new capabilities and opportunities. Today, under Celeros Flow Technology, the company continues to honour the rich legacy of Union Steam Company while embracing modern advancements.
