Grimm's Pump and Industrial Supply interior.

About Us

Providing quality customer service and reliable products to Rapid City and the surrounding area for over 65 years, Grimm's Pump & Industrial supply believes in continuing the pursuit of growth and expansion in the industrial and petroleum industry.

In 1958, brothers Bob and Don Grimm ventured into the service, sales and repair of petroleum handling equipment, along with the professional installation of underground storage tanks. After almost 30 years of successfully operating their business, the Grimm brothers sold the company in 1985.

Brian Wagner, the current owner and President, has since developed Grimm's to be the largest industrial supply company in the Black Hills region. With over 24,000 square feet of warehouse on 4 acres of land, we currently have over 20,000 industrial and petroleum parts in stock.
