About Us

As a 100% employee-owned distribution company, everyone at Cummins-Wagner Co., Inc. is personally invested to ensure your equipment reaches its full potential. We view ourselves as an extension of your team, offering engineered solutions, industry-leading brands, and comprehensive aftermarket services.

Our commitment to you is twofold:
Dedication to solutions – We will find the best solution for your application needs
Dedication to service – We will work with you after the initial sale to install, maintain, and repair any of the products we carry as well as some we don’t.


At Cummins-Wagner, our mission is to provide efficient and effective solutions to mechanical equipment applications by supplying quality products & services to the benefit of our customers, vendors and employees.

We strive to be the leading Manufacturer’s Distributor/Representative Company for sales & service of mechanical equipment in all the markets and trading areas we serve.


Founded in 1960 by “Charlie” Cummins and “Chub” Wagner, Cummins-Wagner serves Maryland, Virginia, Washington DC, Delaware, West Virginia, and Pennsylvania with leading brands of compressors, pumps, and heat transfer equipment, and offers exceptional customer service and support services such as system design, assembly, and aftermarket service and repair.

In 1985, Cummins and Wagner established an ESOP and sold the company to the employees, so now the 200 employee-owners are driven to deliver the best possible products and customer service.

Cummins-Wagner acquired Siewert Equipment and Siewert Classic in 2008, expanding our reach to include markets in New York State and Florida.

In 2012, Cummins-Wagner established its Engineered Process Solutions (EPS) division in West Chester, PA, expanding on the already-growing demand for packaged systems for pressure boosting, heat transfer, fuel oil transfer, and other industrial applications.

More recent acquisitions include Siewert Equipment acquiring J.L. Moore in 2014 for the NY territory. In 2017 Cummins-Wagner acquired EESCO Pump & Valve, which expanded our service capabilities in the Baltimore, Maryland area.

Employee Stock Ownership (ESOP)

As an “ESOP” company with 100% of the common stock universally and exclusively owned by the Employee Stock Ownership Trust (ESOT), employees are motivated to work for the long-term success of the company to a degree unmatched by those of our competitors. The successful ESOP business model typically outperforms non-ESOP companies.

Our company continually invests not only in physical assets such as inventory, tools, and facilities, but also in the latest communication and computer technology for the rapid collection, analysis, and transmission of data. The rapid exchange of information is vital to our success, whether such information is for the benefit of our customers, our sales force, or our trading partners. We strive to be on the cutting edge of technology and equipment that will allow us to better serve both our upstream and downstream trading partners.


Cummins-Wagner is committed to the safety of our employees and work facilities. Our service teams follow an established set of safety procedures and receive continuous and comprehensive training such as regularly scheduled safety meetings, which include pre-job briefings, hazard recognition and accident prevention discussions.

Additionally, Cummins-Wagner has partnered with American Compliance Systems (ACS) to strengthen the company’s commitment to safety in all of our units. Assessment of all the facilities and safety procedures are periodically cataloged by an independent party and procedure adjustments and trainings are formulated as part of ongoing continuous improvement.

In the Community

Cummins-Wagner Co., Inc. is committed to supporting organizations that improve the quality of life and address the needs of the communities represented by our employee-owners, customers, and vendors. Additionally, we are committed to supporting our employee-owners in their efforts to be well-rounded, socially responsible and caring individuals, who make a difference in their communities and the world around them.

Each year, Cummins-Wagner picks several charity organizations to donate to. For 2020, we have selected NAMI (National Alliance on Mental Illness); Operation Second Chance (serving & supporting Veterans and their families) and the Alzheimer’s Foundation of America.

Although we can’t be everything to everybody, it’s nice to share where we are making a difference. Please contact us if you have questions about our Community Impact initiatives.
