Many North Dakotans know that living here is not always glamorous. It's full of hard-working experts that solve everyday problems and keep moving forward to get the job done. Dana Rosendahl, owner and designer of Dyna Flo Inc. in Oakes, ND, has that same drive to survive. General Irrigation and Dewatering is Rosendahl's primary business, with more than forty years of water systems experience. Out of the increased need for pumping water away from ditches, fields, and construction sites, Rosendahl thought he could build a more powerful, more portable, and versatile pump to serve a variety of purposes.

Dyna Flo, short for Dynamic Flow, was born in 2009. The pump
was just as described – easy to use, portable, and highway legal. The pump was
initially used as a piece of rental equipment for General Irrigation during the
wet seasons, but as farmers and construction sites saw the need for the DynaFlo
pump, it became more and more popular. 

Updates and improvements have been made to the original pump
over the years, such as increased usability, variable speeds, and increased
durability. Additional exterior stationary pumps and portable float pump
products have been added to the DynaFlo product line. Each iteration is built
out of need, and with their extensive knowledge in pumps, water, and a good
sensibility, the products are made to last. Because they are made the right
way, Rosendahl says, they have persevered. "Field drainage is our most
popular. It's our niche market," says Rosendahl, "the pumps can use
the same impeller from 5 to 20 hours power, and it can push water in many cases
as far as 3000 feet." That impresses a lot of people, he says with pride.

Dyna Flo has increased its reach globally, with dealerships
in Canada, and more recently, Australia. They learned a lot from their
Australian sales trip, funded through STEP ND. Rosendahl and his wife put on
more than 2000 miles across the Australian countryside, meeting with five
dealerships, a few site visits, and connecting with some business partners
along the way. Unfortunately, their visit to establish dealerships for their
pumps was followed by a significant drought, a series of devastating wildfires,
and a global pandemic. Demand for their pumps has been lower than anticipated
due to the needs and priorities of recent global events.

Rosendahl shared some lessons learned from his trip to Australia
and what he would do differently in the future. "I would have engaged more
government. We thought with the contacts we had. We would be all set." He
goes on to explain that involving the government officials may have made the
trip more meaningful. "There would have been more of a media splash,"
he says, hoping to get a few more eyes on the pumps, which can also be used in
many government projects. Shipping to Australia was different from shipping
overland to Canada, with many more rules and regulations to follow. Rosendahl
also recommended not to be afraid to reach out to the media, "let everyone
you can know what you are doing. You never know who could show up."

Speaking with both Dana and son, Ryan Rosendahl, they
explained their ability to pivot and keep busy throughout every season. With
their experience in both irrigation and draining, wet or dry, the Rosendahl's have
a balance to their business that keeps them operating for the long-run.

The future for DynaFlo includes establishing a more stable
dealer network and continued improvement on the pump systems. For more
