Historical Timeline

Ritter Engineering Company was originally established in 1951 by Wayne G. Ritter and was a franchised distributor of Trabon centralized lubrication systems for the Western Pennsylvania area. Originally located in a small second floor office on West Liberty Avenue in Pittsburgh, the company quickly expanded into the locations surrounding the Great Lakes industrial region.

In 1957 the Chicago branch was opened, followed closely by a Milwaukee branch in 1958. To serve the automotive industry, a Detroit branch was opened in 1963 and an Erie, Pennsylvania branch was opened in 1965. As the branches grew, multiple Parker stores were opened in and around the branches. The company headquarters was moved to Zelienople, Pennsylvania in 1990.

Ritter’s association with Parker Hannifin began in 1953 and the company quickly became one of Parker’s largest distributors within the United States. Ritter is also a leading distributor of Graco lubrication products and Enerpac hydraulic tools and technology as well as more than 50 other industrial tool suppliers.

In 2000, Ritter Engineering changed its name to Ritter Technology LLC, a name more reflective of its diversified capabilities.

In 2018, the parent company Motion & Control Enterprises, LLC was formed, and Ritter Technology was abbreviated and rebranded as RitterTech and positioned as a division under MCE. That same year, MCE diversified its operations and purchased Primet Fluid Systems, Tri-State Hose, and Fluid Systems Engineering.

In 2020, FSE became a part of the RitterTech division and the Solutions Engineering Group was also formed. In 2021, MCE acquired SwansonFlo, Diversified Air Systems, Instrument Associates, and RSA. In 2022, Tri-State Hose became part of the RitterTech division.
