He established a limestone quarry in 1886 at 18th and Main streets. When water seepage became a problem, he developed the first Rotary Internal Gear pump to drain the quarry. His first pump was built in 1904, and a patent application was submitted the same year. In 1911, Nielsen joined with P.C. Petersen (a machinist), W.L. Hearst (a doctor) and George Wyth (a shoe salesman) to form the Viking Pump Company. It was so named because three of the four were of Danish descent, and they likened the first internal gear pump to the notion that the Vikings were the first European explorers of North America. In that year they manufactured fifty pumps, which generated revenues of two thousand dollars. Starting out with two employees in space leased from a washing machine manufacturer, the new company built a 40’ x 60’ factory in 1912, and later expanded to forty employees and three buildings with a total of 12,000 square feet by 1919. The original building is incorporated into today’s 154,000 square foot downtown Cedar Falls headquarters.
