In the mid-1950’s Dakota Pump Inc., under the name Sanders Inc., started manufacturing and marketing package pump stations in Sioux Falls, SD to meet a regional (North & South Dakota, Minnesota, Iowa, and Nebraska) demand. Located in Sioux Falls, SD, the company did well, considering its limited exposure.

In 1967, recognizing the company's potential, investors acquired the company from Sanders Inc. of Sioux Falls, SD and renamed it Dakota Pump Inc., which later moved to its current location in Mitchell, SD. The management philosophy changed from a factory direct regional sales effort to promoting and expanding a representation network, which would eventually cover the entire USA.

In 1971, local businessman, Louis Sebert, was announced as the general manager. As the years passed, Louis Sebert acquired the business. Currently, DPI is owned and operated by Louis’ three sons, Bob, Bill and Jim, who strive to maintain the “family business” atmosphere. DPI is an active provider in the local community, and takes pride in the “family oriented” approach to large water and waste water pumping solutions.
