About Us

General Irrigation & Dewatering of Oakes, ND is licensed in sales, design and installation of deep well and submersible pumps.  We have been selling and installing electric pumps, diesel driven pumps, and PTO pumps for irrigation and industrial applications for over 30 years.  We have extensive knowledge in handling water and a sub-surface and surface dewatering division.

Our company needed a pump for our rental operation.  A pump that could be towed easily, pump alot of water quickly and be affordable.  Drawing from 30 years of knowledge in the irrigation and pump business, Dana Rosendahl- President ⁄ Owner of General Irrigation, designed the Dyna-Flo pump.  He used technologies from deep well turbines, submersibles, centrifugal pumps, and from sewer and trash handling pumps.  Features like the neoprine lined turbine bearings will assure a long life.  Each of the bearings are backed up with a sand collar, which prevents debre and grit from flowing into the bearings.

General Irrigation - manufacturer of the Dyna-Flo pump has been serving the midwest since 1967.
